Mobile Ad Hoc Networks (MANET), Routing Misbehavior, Node Misbehavior, Network Security, Dynamic Source Routing


A mobile ad hoc network consists of nodes that move arbitrarily and form dynamic topologies. Individual mobile nodes communicate with each other directly or indirectly via wireless link. The nodes may attempt to benefit from other nodes, but some nodes refuse to share its own resources. Such nodes are called selfish or misbehaving nodes. The nodes in MANET move freely and may change topology rapidly. These selfish nodes may severely affect the performance of network. Due to such type of node's structure and scarcely available battery-based energy, node misbehaviors may exist. One such routing misbehavior is that some selfish nodes will participate in the route discovery and maintenance processes but refuse to forward data packets. In this paper, the 2ACK scheme is used. The 2ACK scheme serves a technique for routing schemes to detect routing misbehavior and to mitigate their adverse effect. The main idea of the 2ACK scheme is to send two-hop acknowledgment packets in the opposite direction of the routing path. In order to reduce additional routing overhead, only a fraction of the received data packets are acknowledged in the 2ACK scheme. The evaluation of the 2ACK scheme uses the Dynamic Source Routing (DSR) protocol.
