Abstract
An adaptive opportunistic routing algorithm based on utility called URD was proposed
and then the effectiveness of this algorithm was analyzed.At last
this algorithm was implemented using Java by ONE simulation tool and its performance was verified with the classical algorithms:Epidemic
PRoPHET and SprayAndWait.Simulation results show that URD algorithm can increase the probability of encountering opportunity between nodes
improve the efficiency of forwarding packets and reduce the delay overhead of network.
