摘要
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 message transmission on Ad Hoc network and combined with the basic ideas oi re- active routing algorithm AODV and social routing algorithm SimBet, an improved routing algorithm IC -AODV（Interest Difference And Node Centrality based AODV） is proposed. In selecting the node for messages delivery, the physical factors and social factors such as interest difference and node centrality are considered. The simulation with NS2 indicates that compared with I-AODV etc. , IC-AODV could a- chieve fairly high reliability while has fairly low bandwidth overhead.
