Abstract:
With the growing popularity of outdoor locating devices it is both technically and economically feasible for a mobile device to know its physical location. In location-based protocols for multihop wireless networks, routing packets and selecting the correct interface and next hop for a packet being forwarded relies on geographical information of nodes. This requires availability of one static server or number of mobile servers distributed over the network area to provide the destination location. These types of servers suffer from different type of failures due to mobility and single point of failure, which leads to the whole network to go down and heavy load at a single server. In addition, the periods of time spent on looking for a server, and the length of path from a node in the network to the server are other problems. The main objective of this paper is to present a mechanism that overcomes these failures and problems. Results have shown that the proposed mechanism is scalable with the number of nodes, speed and mobility, as well as reducing the time spent on looking for the server, and reducing the path length from a requester node to the server node.
