机会网络的路由性能影响因素研究

Study of Effect Factors on Routing Performance in Opportunistic Networks

影响机会网络路由性能的因素较多,为进一步研究机会网络中路由算法对路由性能的影响,从提高机会网络路由性能的角度出发,研究了如何在路由算法中加入控制消息复制和删除冗余消息对机会网络路由的影响。仿真结果表明,这两种机制的加入能有较改进路由的综合性能,显著提高交付率,减少路由开销,降低传输延迟。

There are many factors influence the performance of the opportunistic networks. To the further study the impact on the routing performance of routing algorithms in opportunistic networks,from the point of increasing routing perform- ance for opportunistic networks, the effect of routine algorithms on the routing performance for opportunistic networks was studied, and the mechanism of control massage copy and delete redundant messages was add in algorithms. The simulation results show that add the two mechanism can improve the performance of the routing and significantly improve the delivery rate ,reduce the routing overhead and reduce the transmission delay.
