Abstract:

Through studying the ways of forwarding information in opportunistic networks,the communication nodes in the neighbourbood can be traversed and the two nodes can be compared.Through the form of the intersection,the neighbor node with the largest XOR is chosen as the next hop to transfer the information so that a communication path with maximum effectiveness is formed. Based on this analysis process, an efficient forwarding strategy based on XOR operation in opportunistic networks (FSXO) is proposed.The proposal is compared with classical algorithms in opportunistic networks,and the simulation results show that the proposed FSXO strategy can reduce the presence of invalid copy data at high transmission rates,thus effectively reduce the routing overhead and resource consumption.
