服务通告和发现在MANET(Mobile Adhoc Networks)网络中,是一个十分重要的组成部分。现有的服务通告和发现协议不是为MANET网络设计的。文章提出了一个适合MANET、基于ZRP(Zone Routing Protocol)的服务通告及发现协议。服务的通告与发现存在于ZRP路由控制分组中,避免了周期性的通告给MANET网络带来的负载,节约了有限的带宽和设备的能耗。
Service advertisement and discovery is an important component for MANET (Mobile Ad hoc Networks). The existing protocols are not designed for mobile ad hoc networks. Service advertisement and discovery protocol for MANET based on ZRP (Zone Routing Protocol) is presented in this paper.Its service advertisement and discovery information exists in the ZRP control packets, thus avoiding excessive traffic overhead of periodic advertisements, and saving precious bandwidth and energy consumption.
