针对Ad Hoc网络中的消息传输问题,结合反应式路由算法AODV和社会性路由算法SimBet基本思想,提出一种改进的路由算法——IC-AODV(基于兴趣因子和中心性的AODV路由算法)。在选择转发节点时,综合跳数等物理因素和节点兴趣差异、中心性这两种社会性因素。随后用NS2对协议进行仿真,结果表明IC-AODV路由协议相比I-AODV(基于兴趣差异的AODV路由协议)等,在较低带宽开销的同时,获得更高可靠性与传输比。
Aiming at the problem of message transmission in Ad Hoc networks, an improved routing algorithm, IC-AODV (AODV routing algorithm based on interest factor and centroid), is proposed by combining reactive routing algorithm AODV and social routing algorithm SimBet. When selecting the forwarding nodes, the two social factors are the physical factors such as hops and the differences in interest of the nodes and the centrality. Then NS2 is used to simulate the protocol. The results show that the IC-AODV routing protocol achieves higher reliability and transmission ratio with lower bandwidth overhead than I-AODV (AODV routing protocol with different interest).
