Service availability routing mechanism for mobile ad hoc networks

Most location service approaches for mobile ad hoc network rely on one static server or number of mobile servers distributed over the network area. These approaches suffer from servers´ failures which cause out-of-date information and hence, using expired location information of the service. In this paper, a solution of such failures is presented through an adaptive server availability mechanism. Some nodes consider themselves as servers according to their locations and situations in the network. Each mobile node periodically updates the servers with its geographical information. Results have shown that the proposed location of service approach is scalable with the number of nodes, and speed.
