Review on Different Techniques used in Selfish Node Detection

Abstract

In present days, mobile ad hoc networks have grown into an emerging research topic. One of the challenging problem in MANET is securing it in an unsafe environment. In MANET, Innumerable intermediate nodes interchange information without the need of infrastructure. To cooperate with each node all nodes participate in packet forwarding. Due to the inadequate energy of the nodes they do not participate in the routing process correctly. When a node tries to attempts the network reserves for its own gain, but unwilling to use its resources for other nodes in the MANET then these nodes are called selfish nodes. The destruction of basic action of the network can occur due to this selfish behavior of the node. These routing misbehaviors can misuse system resources such as power and bandwidth and it can also reduce the packet delivery ratio. Hence, it is necessary to identify and remove such nodes from the network. There are many methods for the identification of selfish nodes. In, this survey various methods for detecting selfish nodes are discussed with their major advantages.
