Abstract: The design of routing protocol in mobile Ad Hoc network is a challenging subject because of its limited node energy and bandwidth.Therefore，multipath routing scheme is considered to balance overload.Two multipath routing algorithms are proposed in this paper.The simple nondisjoint multipath algorithm defines that alternate path is established only by nodes which are those on the primary path or their neighbors.And then the mean length of alternate path decreases.Simulation results show that simple nondisjoint multipath has better performance than node disjoint multipath.It will provide an effective solution for energy efficient and reliable data transportation in wireless network.

摘要： 移动Ad Hoc网络中有限的节点能量和带宽给路由协议设计带来了困难，对此考虑使用多路径机制来平衡负载，并提出了两种多路路由算法。其中，简单相关多路路由算法规定替换路径只能由主路径节点或其相邻节点构成，从而减小了替换路径的平均长度。仿真结果显示简单相关多路路由算法比节点不相关多路路由算法具有更好的性能，它将为无线网络中实现节能及可靠传输提供一种有效的途径。
