InstructionMobile commerce (m-commerce)Aset of business activities conducted over mobile and wireless networks using applications on handheld devices. Mobile phones and  provide features such ashigh mobilitypersonalisation (through location, proximity, contextualisation, or feature evolution)large user demographic3
Instruction   cont.Providing location information for the servicesrequiring significant change in the software and hardware and/or the handsetLocation information is essentially a two-stage processprovide geographical position of the mobile user provide the information on a particular product or service related to that location4
Instruction   cont.The problem of locating the geographical position of the mobile phone usersall mobile phone systems effectively track a users whereabouts at the cellular levelEach cell site has a unique Cell-IDThis Cell-ID can be used as a filter for localised information although the accuracy is relatively crude, between 100 m and 12 km5
Instruction   cont.The framework which enable higher degrees of accuracy, between 1 and 50 m, could be elements such asthe locations of the base stations of a mobile phone networksatellites of the global positioning system (GPS)enhanced observed time difference (EOTD)6
Instruction   cont.These measured solutions achieve high degrees of positional accuracy. The  disadvantageThe calculations can be performed at the handset In the infrastructure requiring the system software to be upgraded to facilitate this processthey suffer inaccuracies7
Instruction   cont.They suffer inaccuracies when the line of site between the mobile user and the infrastructure is obscured. GPS based systems in urban environments buildings can obscure a direct view of three satellites preventing measurements being made creating the so-called urban canyon effect.8
Instruction   cont.An alternative approach is to ascertain location from the users interaction with objects of known location.The interaction could be proximity within a physical area using communication technologies such asWiFi, Bluetooth, or two dimensional (2D) bar codes (QR codes, radio frequency identification (RFID) tags)9
Instruction   cont.2D barcodes and RFIDThe advantage is that they can be passive solutions in that they do not require a power source in the object itself.use a phone with an on-board camerathrough interaction with an online database whilst the RFID systemsAnother advantage is that they avoid measurement problems and thus can readily be deployed in indoor and urban environments. 10
Instruction   cont.The second part of the location process is the spatial informationrepresent data may be as a symbol on a mapmore sophisticated services will need to interpret the raw positional data and proximity to other mobile usersa number of data formats and standards have emerged such as spatial data bases supported by positional forms of XML11
Instruction   cont.We present an implied location advertising solution using Bluetooth. The system provides location based information/advertisements at an accuracy of around 10 m requires no software to be installed on the phone allows users to instantaneously opt-in to the service.12
Bluetooth location based systemThe obvious choice is Bluetooth which is in fact increasing its growth. Nokia is predicting a year-on year increase of 65% in 2006. Bluetooth is currently present in 65% of all mobile phone handsets. Bluetooth is a very practical and worthwhile scenario.13
Bluetooth location based system   cont.Bluetooth is used as a means of targeting users with specialized content in a specific area at a given time.Figure 1 shows the basic layout of a system for transmitting messages to all the devices in a given area.14Fig. 1  Basic Bluetooth message system
System implementationsWe  will present two particular use case scenarios: Supermarket adverts/couponsGuide system15
Supermarket adverts/couponsA system is implemented in a supermarket to supply customers with the latest information on products or highlight particular special offers. We will require a number of message centers scattered throughout the storeCustomers tend to browse the environment rather than find the optimal route. 16
Supermarket adverts/coupons   cont.One of the major concerns is how to ensure that the same message is never sent twice to one device. To facilitate the fact that devices will roam between different locations, and to prevent duplicate messages, an integrated backend information system is required.17
Supermarket adverts/coupons   cont.Figure 2 shows the layout for two sites, each of them pushing messages (adverts/coupons) to the potential customers.18Fig. 2  Roaming device between different Bluetooth sites
Supermarket adverts/coupons   cont.The messages can be tagged to expire in the database after a certain amount of time.To improve and better target potential customers, the information system can be altered to remember the devices that take advantage of the coupon.19
Guide systemA system is implemented at a tourist attraction providing users with key information about the location.They will be sending out different messages depending upon their location within a particular tourist spot.20
Guide system   cont.The message could beInformation about the current location.Information about other points of interest in the same location.This particular tourist spot will close in certain amount of time.other tourist attractions in the vicinity21
Guide system   cont.For example, the system implemented at the historic site of Lancaster Castle.entry to the castle receive a brief history of the castleits current use as a working gaol and courtgets within the range of another Bluetooth sitelocated near the castle courtyardanother message giving details of the site were the Pendle witches were hung on 16 November 181222
Guide system   cont.Different Bluetooth sites within the castle provide different messages to the user. The information system will keep track of the devices discovered by each site and the messages sent to them. 23
Application designFigure 3 illustrates the different processes involved, within the entire system, to discover and send messages to users.24
Application design   cont.The specific details of the system operation are shown in Fig. 425Fig. 4  Message sites Interacting with database
Application design   cont.This example is of a message received on a Bluetooth enabled handset as part of an information system implemented in the Informatics Group of Infolab21 at Lancaster University, UK.26Fig. 5  Bluetooth news alert at InfoLab21
ConclusionsAccording to Barwise and Strong, in SMS m-advertising, 81% of the test subjects viewed all the messages before deleting them and 77% of them did that as soon as they received the advertisement.users are more likely to take advantage of the offers that could accompany the advertisements further increasing the likelihood of use.27
Conclusions   cont.the system presented in this paper allows users to choose  whether  they  want  to  receive  information  or not   turning   on   or   off   their   Bluetooth receptionOne of the great benefits of this system is it can be deployed  without  requiring  the  users  to  do  anything more   complicated  than   switch  on   their   Bluetooth capability  and  accept  the  message.28
