Vehicular Ad Hoc Networks (VANETs) have been envisioned with three types of applications in mind: safety, traffic management, and commercial applications. By using wireless interfaces to form an ad hoc network, vehicles will be able to inform other vehicles about traffic accidents, hazardous road conditions and traffic congestion. Commercial applications (e.g., data exchange, audio/video communication) are envisioned to provide incentive for faster adoption of the technology. To date, the majority of VANET research efforts have relied heavily on simulations, due to prohibitive costs of employing real world testbeds. Current VANET simulators have gone a long way from the early VANET simulation environments, which often assumed unrealistic models such as random waypoint mobility, circular transmission range, or interference-free environment (Kotz et al. (2004)). However, significant efforts still remain in order to enhance the realism of VANET simulators, at the same time providing a computationally inexpensive and efficient platform for performance evaluation of VANETs. In this work, we distinguish three key building blocks of VANET simulators: – Mobility models, – Networking (data exchange) models, – Signal propagation (radio) models. Mobility models deal with realistic representation of vehicular movement, including mobility patterns (i.e., constraining vehicular mobility to the actual roadway), interactions between the vehicles (e.g., speed adjustment based on the traffic conditions) and traffic rule enforcement (e.g., intersection control through traffic lights and/or road signs). Networking models are designed to provide realistic data exchange, including simulating the medium access control (MAC) mechanisms, routing, and upper layer protocols. Signal propagation models aim at realistically modeling the complex environment surrounding the communicating vehicles, including both static objects (e.g., buildings, overpasses, hills), as well as mobile objects (other vehicles on the road). We first present the state-of-the art in vehicular mobility models and networking models and describe the most important proponents for these two aspects of VANET simulators. Then, we describe the existing signal propagation models and motivate the need for more]]>

Recent advances in wireless networks have led to the introduction of a new type of networks called Vehicular Networks. Vehicular Ad Hoc Network (VANET) is a form of Mobile Ad Hoc Networks (MANET). VANETs provide us with the infrastructure for developing new systems to enhance drivers’ and passengers’ safety and comfort. VANETs are distributed self organizing networks formed between moving vehicles equipped with wireless communication devices. This type of networks is developed as part of the Intelligent Transportation Systems (ITS) to bring significant improvement to the transportation systems performance. One of the main goals of the ITS is to improve safety on the roads, and reduce traffic congestion, waiting times, and fuel consumptions. The integration of the embedded computers, sensing devices, navigation systems (GPS), digital maps, and the wireless communication devices along with intelligent algorithms will help to develop numerous types of applications for the ITS to improve safety on the roads. The up to date information provided by the integration of all these systems helps drivers to acquire real-time information about road conditions allowing them to react on time. For example, warning messages sent by vehicles involved in an accident enhances traffic safety by helping the approaching drivers to take proper decisions before entering the crash dangerous zone (ElBatt et al., 2006) (Xu et al., 2007). And Information about the current transportation conditions facilitate driving by taking new routes in case of congestion, thus saving time and adjusting fuel consumption (Dashtinezhad et al., 2004) (Nadeem et al., 2004). In addition to safety concerns, VANET can also support other non-safety applications that require a Quality of Service (QoS) guarantee. This includes Multimedia (e.g., audio/video) and data (e.g., toll collection, internet access, weather/maps/ information) applications. Vehicular networks are composed of mobile nodes, vehicles equipped with On Board Units (OBU), and stationary nodes called Road Side Units (RSU) attached to infrastructure that will be deployed along the roads.]]>

3. What is a register variable? Register variables are stored in the CPU registers. Its default value is a garbage value. Scope of a register variable is local to the block in which it is defined. Lifetime is till control remains within the block in which the register variable is defined. Variable stored in a CPU register can always be accessed faster than the one that is stored in memory. Therefore, if a variable is used at many places in a program, it is better to declare its storage class as register Example: register int x=5; Variables for loop counters can be declared as register. Note that register keyword may be ignored by some compilers. 4. Where is an auto variables stored? Main memory and CPU registers are the two memory locations where auto variables are stored. Auto variables are defined under automatic storage class. They are stored in main memory. Memory is allocated to an automatic variable when the block which contains it is called and it is de-allocated at the completion of its block execution. Auto variables: Storage : main memory. Default value : garbage value. Scope : local to the block in which the variable is defined. Lifetime : till the control remains within the block in which the variable is defined. 5. What is scope & storage allocation of extern and global variables? Extern variables: belong to the External storage class and are stored in the main memory. extern is used when we have to refer a function or variable that is implemented in another file in the same project. The scope of the extern variables is Global.]]>

Q: Is it possible to have Virtual Constructor? If yes, how? If not, Why not possible? A: There is nothing like Virtual Constructor. The Constructor can‟t be virtual as the constructor is a code which is responsible for creating an instance of a class and it can‟t be delegated to any other object by virtual keyword means. Q: What is constructor or ctor? A: Constructor creates an object and initializes it. It also creates vtable for virtual functions. It is different from other methods in a class. Q: What about Virtual Destructor? A: Yes there is a Virtual Destructor. A destructor can be virtual as it is possible as at runtime depending on the type of object caller is calling to, proper destructor will be called. Q: What is the difference between a copy constructor and an overloaded assignment operator? A: A copy constructor constructs a new object by using the content of the argument object. An overloaded assignment operator assigns the contents of an existing object to another existing object of the same class. Q: Can a constructor throws an exception? How to handle the error when the constructor fails? A:The constructor never throws an error. Q: What is default constructor? A: Constructor with no arguments or all the arguments has default values.]]>

A computer network consists of nodes and communication links which implement its protocols. It interconnects a set of hosts which conform to the network protocols.  A network may be classified as a LAN, MAN, or WAN, depending on its geographic spread, and as private or public, depending on its access restrictions. It may employ a point-to-point or a broadcast communication www.ThesisScientist.com Chapter 1: Introduction 15 model. A point-to-point model may be based on circuit switching or packet switching. The OSI model proposes a seven-layer architecture for networks. Each layer is characterized by a set of protocols. The network nodes implement only the bottom three layers, while the hosts implement all the layers.  The physical layer controls the transmission of raw data bits over communication lines. The data link layer facilitates the reliable transfer of data over communication channels. The network layer controls the end-to-end routing of data across the network. The transport layer manages the efficient and cost-effective transportation of data across the network. The session layer manages the negotiation of the establishment and termination of connections (sessions). The presentation layer provides a mutually-agreeable binary representation of application data (syntax). The application layer provides a mutually-agreeable meaning of application data (semantics).  A service primitive is an abstract representation of the interaction between a service provider and a service user, and may be of one of four types: request, indication, response, and confirmation.  A sequence diagram defines a service protocol by specifying the permissible sequence of service primitives that may be exchanged between service users and service providers.  A state transition diagram describes the various execution states a station can assume and how service primitives cause it to transit from one state to another.  Communication standards are essential in order to achieve interoperability between different equipment and networks.]]>

J2EE (Java 2 Enterprise Edition) is an environment for developing and deploying enterprise applications. The J2EE platform consists of J2EE components, services, Application Programming Interfaces (APIs) and protocols that provide the functionality for developing multi-tiered and distributed Web based applications.that can be used remotely through a remote interface either synchronously or asynchronously (e.g. Web service, messaging system, sockets, RPC etc). Containers (Web & EJB containers) are the interface between a J2EE component and the low level platform specific functionality that supports J2EE components. Before a Web, enterprise bean (EJB), or application client component can be executed, it must be assembled into a J2EE module (jar, war, and/or ear) and deployed into its container. A J2EE server provides system level support services such us security, transaction management, JNDI (Java Naming and Directory Interface) lookups, remote access etc. J2EE architecture provides configurable and non-configurable services. The configurable service enables the J2EE components within the same J2EE application to behave differently based on where they are deployed. For example the security settings can be different for the same J2EE application in two different production environments. The non-configurable services include enterprise bean (EJB) and servlet life cycle management, resource pooling etc. Protocols are used for access to Internet services. J2EE platform supports HTTP (HyperText Transfer Protocol), TCP/IP (Transmission Control Protocol / Internet Protocol), RMI (Remote Method Invocation), SOAP (Simple Object Access Protocol) and SSL (Secured Socket Layer) protocol.]]>

Java is a fun language. Let’s look at some of the reasons: Built-in support for multi-threading, socket communication, and memory management (automatic garbage collection). Object Oriented (OO). Better portability than other languages across operating systems. Supports Web-based applications (Applet, Servlet, and JSP), distributed applications (sockets, RMI. EJB etc) and network protocols (HTTP, JRMP etc) with the help of extensive standardized APIs (Application Program Interfaces). Java does not support pointers. Pointers are inherently tricky to use and troublesome. Java does not support multiple inheritances because it causes more problems than it solves. Instead Java supports multiple interface inheritance, which allows an object to inherit many method signatures from different interfaces with the condition that the inheriting object must implement those inherited methods. The multiple interface inheritance also allows an object to behave polymorphically on those methods. [Refer Q 8 and Q 10 in Java section.] Java does not support destructors but rather adds a finalize() method. Finalize methods are invoked by the garbage collector prior to reclaiming the memory occupied by the object, which has the finalize() method. This means you do not know when the objects are going to be finalized. Avoid using finalize() method to release non-memory resources like file handles, sockets, database connections etc because Java has only a finite number of these resources and you do not know when the garbage collection is going to kick in to release these resources through the finalize() method. ]]>
