基于ZRP的移动自组网服务发现模型研究

A research on service discovery model for mobile Ad Hoc networks based on ZRP

在节点移动性大、资源受限的移动自组网中,服务的自动发现至关重要.但现有的服务发现协议都缺少一种自适应机制,控制开销和服务请求时延等问题.为此,提出了一种基于混合区域路由协议ZRP的网络层服务发现模型ZSDMAN.该模型结合使用了路由区域半径调节机制,节点可自动调节区域半径的大小以适用网络拓扑结构变化.

As far as high mobility,resources constrained mobile Ad Hoc Networks is concerned,the service discovery protocol is so important.But the control overhead and query latency by the existed protocols issued are two serious problems.So we proposed a Service Discovery Model for Mobile Ad Hoc Networks based on ZRP(ZSDMAN).This model incorporates the zone radius determination algorithms,which enables the nodes to dynamically and automatically adjust their zone radii for adapting the change of network environment.
