Opportunistic network realizes the communication between nodes by "storage-carry-forward" mode, the traditional routing algorithms can not be applied to the opportunistic network, to address the problems in opportunistic networks that nodes employing routing algorithms based on epidemic mechanism can't sense their neighboring nodes timely and many redundant data packets permeate through the network. This article proposes network routing algorithm based on an efficient opportunistic network. The algorithm is based on network coding method to solve routing problems, compared with existing routing method. NCRA method can handle dynamic route to improve the transmission success rate and reduce the transmission delay, reduce the routing overhead and short the buffer time, decrease the hops of overall opportunistic network.
