| 摘 要： | 提出了一种新颖的分析模型来计算无线ad hoc网络中多路径情况下的负载。该模型考虑到多路径的数目、路由的选取方法以及网络中节点的密度等条件，能够对不同网络条件下的负载进行较好的分析与理论计算。仿真结果与理论计算有良好的一致性，结果表明在无线ad hoc网络中简单地使用多路径路由并不能有效地平衡网络负载。这一结论与目前普遍认定的结论（在无线ad hoc网络中使用多路径路由和在有线网络中使用多路径路由一样，可以很好地平衡网络负载、增加网络的吞吐量）是不一致的。

| Abstract: | A novel analysis model for computing the load of wireless ad hoc network that uses multipath routing was proposed. This model took the number of paths, the way of route selecting and the density of the network nodes into account and could analyse or compute the load in different network conditions. The result of the simulation fits the theory perfectly and give the conclusion that using multipath routing alone in wireless ad hoc network can not balance the load of network effectively. This is not the same as we always accept (using multipath routing in wireless ad hoc network can balance the load of network and increase throughput just as in the normal network). |
