DSMANET: Defensive Strategy of Routing Using Game Theory Approach for Mobile Adhoc Network

Abstract

The Ad hoc technology enables a unique network namely mobile Ad hoc Network (MANET), where the establishment of the routing is a challenging task because of various characteristics such as mobility of the node and resource constraints of individual nodes. The self-configurability of the nodes makes the network vulnerable to initiate different forms of attacks in a very easy way. The malicious activities by the nodes are identified by its behavior of deceiving the other nodes data using participating into routing then dropping the packets, at the same time similar activities of packet drop could happen by non-malicious nodes due to some fault in the nodes. It is a challenging task to distinguish these two categories of nodes. Most of the current approaches focus on the trust building by the previous behavior of the nodes and black listing it, this approach leads to minimize the size of the network and sometimes permanent clustered network partition which leads to network failure. This paper introduces a novel strategy of defensive approach by the regular nodes as opposed to the malicious node and the method is named as “Defensive Strategy in MANET (DSMANET).” The performance parameters like throughput and routing overhead is compared with one of state of the art secure routing method DSMANET and found exhibiting better performance.
