Privacy-preserving location-based services for mobile users using directional service fetching algorithm in wireless networks

摘要

The wireless network has been utilized for several purposes in modern information world. Among them, the data collection and service access has been identified as key issue. As the services in wireless networks accessed through different intermediate nodes, it is necessary to consider various factors like route, traffic condition, throughput, latency and so on. Also, the location based service selection (LSS) has been identified as keen challenge in accessing any service. According to this, number of methods discussed earlier but no such method exists which achieve expected performance. To improve the performance, an efficient mobility aware directional service fetching algorithm (MADSF) is presented in this paper. The algorithm performs lookup about different services available around the user location. By fetching the trust are relation on verified route selection represents the directional approach based on the services identified, services present in the direction of user and estimates data pickup rate (DPR) for each service based on different properties of the route and service. Finally, user selected the current meet by the point single service selection and produces result to the user. The proposed MADSF-DPR algorithm improves service selection by the point of location aided service selection process and throughput in wireless networks.
