In wireless ad hoc networks, nodes are energy constrained. As they communicate far off destinations using intermediate relays, it may not be in interest of a node to expend its energy in relaying and consequently reducing its own lifetime. On the other hand, if all nodes decide not to always accept relay requests, the network throughput will drop dramatically i.e., the lifetime of the whole network...
