摘　　要：针对传统OLSR协议应用于无人机自组网中时可能会选取与源节点间链路连接易断开并且剩余能量低的节点作为MPR的不足,对传统的MPR选取算法进行改进,改进后的LEC-OLSR协议中MPR选取算法综合考虑了节点间链路生存时间、节点剩余能量和节点深度这3种影响因素,利用层次分析法构建判断矩阵精确地计算各影响因素的权重因子,并将它们的加权和作为MPR节点的选取标准.利用OMNeT++软件在节点个数递增场景下对OLSR协议和LEC-OLSR协议进行仿真.仿真结果表明,LEC-OLSR协议虽然带来了更大的路由开销,但在节点存活率、分组投递率和平均端到端时延上都有一定程度的提升.Aiming at the shortcomings of the traditional OLSR protocol used in the FANET,the node with the link connection with the source node that was easily disconnected and the remaining energy was low may be selected as the MPR.The traditional MPR selection algorithm was improved.The MPR selection algorithm in improved LEC-OLSR protocol comprehensively considered the three influencing factors of the link lifetime between nodes,the remaining energy of the node and the degree of the node,and used the AHP to construct a judgment matrix to accurately calculate the weight factors of each influencing factor,and calculate their weights.The weighted sum was used as the selection criterion for MPR nodes.Finally,OMNeT++software was used to simulate the OLSR protocol and the LEC-OLSR protocol under the scenario of increasing the number of nodes.The simulation results showed that although the LEC-OLSR protocol brought greater routing overhead,it had a certain degree of improvement in node survival rate,packet delivery rate and average end-to-end delay.
