In Mobile Ad hoc NETworks (MANETs), a set of interacting nodes should cooperatively implement the routing functions to enable end-to-end communication along dynamic paths composed by multi-hop wireless links. Several multi-hop routing protocols have been proposed for ad hoc networks and most popular ones include: Dynamic Source Routing (DSR), Optimized Link-State Routing (OLSR), Ad hoc On-demand Distance Vector (AODV) and Destination-Sequenced Distance-Vector (DSDV). Most of these protocols rely on the assumption of a trustworthy cooperation among all participating nodes; unfortunately, this may not be a realistic assumption in real hosts. Malicious hosts could exploit the weakness of MANET to launch various kinds of attacks. Node mobility on ad hoc network cannot be restricted.
