Energy-based Probabilistic Routing Protocol Using History of Encounters and Transitivity in Opportunistic Network

In the opportunistic network, it might mot exist an end-to-end path during the nodes.In order to reduce the network overhead, based on the characteristic of probabilistic routing algorithm, we proposes an energy-based probabilistic routing protocol using history of encouters and transitivity.Firstly, the communication overhead should be computed when two nodes encounters.Sendly, this algorithm take node′s rest energy as parameter into methed, and choose the node which has the maximun rest energy as forwarding node.Finally, the message is send to other node.The simulation shows that EBPROPHET has good routing performance.It also extends the network′s lifetime.
