Failure Detection in MANETs based on geographical repartition of nodes

MANETs (Mobile Ad hoc NETworks) are characterized by a dynamic topology and generally deployed in a hostile environment with limited resources. Therefore, the design of fault tolerant applications in this environment is paramount as nodes are often subject to failures. We exploit in this paper a solution based on geographic area node repartition to provide a virtual centralization of the network to monitor the failure detection procedure. Hence, we define our protocol called, ARFAD (Area Repartition Failure Detection) that allows a fast detection of a failure while reducing significantly the traffic overhead. We report simulation results performed on NS2 platform that compare the performances of ARFAD with a recent protocol.
