通过对机会网络中节点传递信息的方式进行研究分析,遍历可以通信的邻居节点,将两节点的信息作比较。通过交集的形式,选择节点中携带信息异或程度最大的邻居节点作为下一跳进行信息传递,从而形成一条有效性最大的通信路径。基于这样的分析过程,提出了一种基于异或运算的机会网络高效转发策略FSXO。通过与机会网络中的经典算法对比,仿真结果表明,FSXO策略能够在高传输成功率的情况下,减少网络中无效数据副本的存在,从而有效地降低路由开销,减少资源的消耗。
Through the research and analysis of the ways in which the nodes in the opportunistic networks transmit information, the neighbors that can communicate are traversed, and the information of the two nodes is compared. In the form of intersection, the neighbor node with the largest degree of information XOR in the selected node is selected as the next hop to transmit the information, so as to form a communication path with maximum effectiveness. Based on this analysis process, an opportunistic network efficient forwarding strategy FSXO based on XOR is proposed. Compared with classical algorithms in opportunistic networks, the simulation results show that FSXO can reduce the existence of invalid data copies in the network under the condition of high transmission success rate, so as to effectively reduce the routing overhead and reduce the resource consumption.
