Abstract In this paper, a novel cooperative routing protocol is proposed in Ad hoc networks. A minimal energy multinodes cooperative path is built with the cooperative transmission of neighbor nodes and comparison of total power consumption. Under the assumption that nodes can know the relative location of neighboring nodes, the distributive routing scheme can be implemented by carrying information about power consumption of route and cooperative cluster in Router Requirements (RREQ) packet. Simulation results show that the energy-saving performance can be significantly improved compared with traditional non-cooperative routing. Meanwhile, using the selection strategy of cooperative nodes, the control expense and complexity of computation can be reduced, trading off a little decline in energy-efficiency.
