A Systematic Execution of Collaborative Tracking and Position Sensing for Non-GPS Mobile Using WPAN and GPS Mobiles

Disruption tolerant networks (DTNs) are sparse mobile ad hoc networks where nodes connect with each other intermittently. Since DTNs allow people to communicate without network infrastructure, they are widely used in battlefields, wildlife tracking, and vehicular communications. Location information is extremely important to enable context-aware and location-based applications. However, due to the lack of fixed infrastructure and continuous network connection in DTNs, identifying the location of mobile users and tracking their movement trajectories are challenging. With the increasing number of location dependent applications, positioning and tracking a mobile device becomes more and more important, but the positioning and tracking techniques in a sparse disruption tolerant network have not been well addressed. To overcome this approach proposed a decentralized cooperative method to track exactly the Non GPS mobile users. A simulation result shows that the proposed approach performs better than other existing approaches because here time and end to end delay decreasing while network balancing increasing level.
