[Abstract]:The hybrid routing optimization design of opportunistic networks can effectively reduce redundant overhead and improve the success rate of data transmission. The traditional method uses link cost evaluation and energy-saving delay tolerance algorithm to realize the routing design of opportunistic networks. When node sparse scheduling occurs in mobile ad hoc networks the link has asymmetry and reduces the quality of routing assignment. A hybrid routing optimization algorithm based on improved OLSRv2 algorithm for link asymmetric predictive control opportunistic networks is proposed. The concept of mixed confidence factor in opportunistic networks is defined, and the determination of route optimization test statistics and the design of discriminant system are studied. The probabilistic routing is introduced by OLSRv2 algorithm and the routing information in the current connected domain is compressed to obtain the optimal transmission probability. The simulation results show that the opportunistic network routing designed by this algorithm can achieve less control overhead, improve the communication success rate, and reduce the network load significantly.
