Proposing an Effective Retransmission Using the Relaying Nodes for Multihop Networks
Coop MAC has been recently proposed as a possible implementation of cooperation protocols in the Medium Access Control (MAC) layer of a wireless network. However, some nodes may refrain from cooperation for selfish purposes, e.g. in order to save energy, in what is called selfish behavior or misbehavior. This protocol violation worsens other nodes' performance and can be avoided if other nodes detect and punish (e.g. banning from the network) misbehaving nodes. However, fading and interference may prevent nodes from cooperating even if they are willing; therefore it is not trivial to identify misbehaving nodes.
