Enhanced shortest Path and Query Response Time for Users in Location Based Service
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2015, Vol 4, Issue 7
Abstract
The most important brave on answering live shortest paths is scalability, in terms of the number of clients and the amount of live traffic updates. An innovative and talented solution to the shortest path computation is to televise an air index over the wireless network called index transmission model. The most important advantages of this model are that the network overhead is self-determining of the number of clients and each client only downloads a portion of the entire roadmap according to the index information. For occurrence the proposed index comprises a set of pair wise smallest amount and maximum travelling costs between every two sub partitions of the road map. Though, these methods only resolve the scalability issue for the number of clients but not for the amount of live traffic updates. There-computation time of the index takes 2 hours for the San Francisco (CA) road map. It is prohibitively costly to update the index for OSP, in order to keep up with live traffic situation.
