With the HaversinFormula this is being calculated and the result can either be that a subscriber is found in an advertising zoneor not. If there is no match then nothing happens but if the subscriber is in an advertising zone then the systemneeds to deliver an advert via SMS.4. RESULTSThe main aim of this paper was to create a system that is able to send advertisements based on the location ofits subscribers. The system was divided into three main parts: Website, Application and SMS messaging system.Each on of these three main modules had a list of specifications that had to be designed, developed andintegrated with the rest of the system.Different testing strategies were adopted to ensure that the implementation was in line at every progressivestage. Unit testing was carried out after every subtask was completed to check that each componentworked well. Integration testing was performed when components were integrated together, to ensure thatcomponents worked well in conjunction with each other. System testing ensured the end-to-end quality ofthe entire system.4.1 Application Testing ResultsIn order to verify that the application works correctly, a series of tests were carried out. The results obtainedfrom these tests enabled us to understand the weaknesses of the system and thus help us correct and improvethe application. We made sure that the application worked in different scenarios and also verifying that theapplication does what it needs to do. The outcome from the results obtained shows that the application createdis robust.The targets set in the beginning of this paper have been accomplished and the system has all the featuresmentioned in the aims implemented. From the results obtained it can also be said that the system is quite robustand has good error handling capabilities.5. CONCLUSIONA location-based service has been created to allow advertisements to be sent to subscribers based on theirlocation. The expectations set in the beginning seemed impossible but yet in the end the implementation waseffectively tackled step by step and all the required tasks were accomplished. The system was divided intomodules which were easier to handle in the various stages outlined. The end result was precisely that whichwas initially described as the ultimate goal: a location-based mobile advertising platform.REFERENCESAG, YellowMap. 2002. Business Models for LBA.
