2ACK-Scheme: Routing Misbehavior Detection in MANETs Using OLSR
Shalini V. Wankhade · 2012
A Mobile Ad Hoc Network (MANET) is a collection of mobile nodes (hosts) which communicate with each other via wireless links either directly or relying on other nodes such as routers. Due to the dynamic change in topology finding route is very difficult. Some nodes misbehaves as they participate in route establishment phase but refuse to forward the data packets to conserve their own energy. For detecting routing misbehavior in MANETs lot of techniques are there such as watchdog, pathrater, TWOACK, SACK, End to End ACK scheme. But due to the disadvantages of the above scheme we propose a new scheme called 2ACK and the routing protocol used is Optimized Link State Routing (OLSR). The fundamental concept of the 2ACK scheme is to send two hop acknowledgment in opposite direction to routing path, we simulate the results in NS-2.
