本文的动机是，观察到传统的临时路由协议不是移动临时网络中的消息传递应用程序的适当解决方案（例如，电子邮件）。快速移动速度，不良路线的比例越大，无限的消息可容忍传统延迟以外的延迟，我们主张一种基于中继的方法与传统的临时路由协议相连。到达目的地的路线不可用，节点在其直接邻居的网络中执行受控的本地广播（继电器）。很可能是不存在的或破坏的 - 很有可能将中继的数据包的继电器节点之一会遇到一个有效的，短（常规的）通往最终目的地的节点，从而增加了可能性的可能性在各种节点运动模型下，我们的模拟结果将成功传递。
This paper is motivated by the observation that traditional ad hoc routing protocols are not an adequate solution for messaging applications (e.g., e-mail) in mobile ad hoc networks. Routing in ad hoc mobile networks is challenging mainly because of node mobility – the more rapid the rate of movement, the greater the fraction of bad routes and undelivered messages. For applications that can tolerate delays beyond conventional forwarding delays, we advocate a relay-based approach to be used in conjunction with traditional ad hoc routing protocols. This approach takes advantage of node mobility to disseminate messages to mobile nodes. The result is the Mobile Relay Protocol (MRP), which integrates message routing and storage in the network; the basic idea is that if a route to a destination is unavailable, a node performs a controlled local broadcast (a relay) to its immediate neighbors. In a network with sufficient mobility – precisely the situation when conventional routes are likely to be non-existent or broken – it is quite likely that one of the relay nodes to which the packet has been relayed will encounter a node that has a valid, short (conventional) route to the eventual destination, thereby increasing the likelihood that the message will be successfully delivered. Our simulation results under a variety of node movement models demonstrate that this idea can work well for applications that prefer reliability over latency.
