说明：  一个EPI路由协议的实现，基于TORA算法，在NS2仿真平台编译通过，主要用于稀疏环境的MANET路由，仿真显示性能优于AODV，DSDV等原有AD HOC路由，思想在于引入基于节点遇见概率下的泛洪路由，适合开放MANET路由协议者参考。
(A routing protocol EPI realize, based on the TORA algorithm, in the NS2 simulation platform compiler passed, mainly used in sparse environment, MANET routing, simulation shows better performance than AODV, DSDV, such as the original AD HOC Routing, thought is the introduction of node-based met under the probability of flooding routing, MANET routing protocols suitable for open reference.)
