Aiming at the problem of the frequently changes of topology and limited energy of nodes in Ad Hoc networks

a load balancing routing protocol based on ODMRP called LB-ODMRP is proposed

in which the path is constructed based on a greedy forwarding mechanism

and in the consideration of the link lifetime and residual energy of nodes and energy balance of nodes

the model of routing quality is introduced to establish backup path

which enhances the robustness

energy consumption in the network can be fairer and extends the whole networks survive time.Simulation result prove the validity of the protocol.
