Impact of Selfish Node Concentration in MANETs

Abstract

The communication in Mobile Ad hoc Network (MANET) is multi-hop in nature wherein each node relays data packets of other nodes thereby spending its resources such as battery power, CPU time and memory. In an ideal environment, each node in MANET is supposed to perform this community service truthfully. However this is not the case and existence of selfish nodes is a very common feature in MANETs. A selfish node is one that tries to utilize the network resources for its own profit but is reluctant to spend its own for others. If such behaviour prevails among large number of the nodes in the network, it may eventually lead to disruption of network. This paper studies the impact of selfish nodes concentration on the quality of service in MANETs.

The Impact of Node Misbehavior on the Performance of Routing Protocols in MANET

“…Gupta S. et. al studied the effect of selfish nodes concentration on the quality of service in MANET networks [12]. The experimental results showed that up to a concentration level of 10%, selfish nodes do not have remarkable negative effect on the network performance.…”

Auction-based bandwidth allocation and scheduling in noncooperative wireless networks

“…Such networks are called non-cooperative networks. The network performance and availability may be adversely affected by the non-cooperative users [5].…”

False Alarm Method for Detecting Selfish Node in Manet

“…By momentarily modifying the direction of information flow, the benefits of selfish sending as well as the sturdiness brought about by opportunistic redirecting can still be obtained when managing interaction voids. Traditional gap managing method works badly in cellular surroundings while VDVH works quite well [2].…”
