A Survey on Selfishness Handling in Mobile Ad Hoc Network
In MANETs some of the nodes do not take part in forwarding packets to other nodes to conserve their resources such as energy, bandwidth and power. The nodes which act selfishly to conserve their resources are called selfish nodes. The selfish nodes are engaged to reduce data availability and produce high communication cost in terms of query processing. Many selfish node detection methods are found to detect the nodes which do not participate in packet forwarding but they fail to detect the selfish nodes which does not allocate replica for the purpose of other nodes. This paper provides methods to detect selfish nodes in terms of allocating replica to other nodes.
