Hey All, In this post we discuss about selfish nodes and how to simulate selfish node scenario using ns2. MANET is self-constrained network, each node should collaborate with each other to perform functions of the network but sometimes node may behave selfishly to conserve their resource like batter power, bandwidth etc. Such nodes are called selfish node and selfishness disturb the network and take away the network from their regular mission. The term selfish node mainly comes from a specific class of AdHoc Networks known as cooperative networks, where different autonomous and as well as heterogeneous nodes (possibly owned by different individuals) form a network and agree to forward each others packet in cooperative manner. The biggest problem in this type of network is "selfish node problem", where some may start dropping the packets of others just for its own benefit (to save the power) There are two commonly known techniques to with t...
