Ad Hoc网络中实现定位的OLSR协议研究

OLSR protocol for positioning in Ad Hoc networks

针对Ad Hoc网络中的节点位置估计和路由控制问题,在基于OLSR(最优链路状态路由)协议的基础上提出了一种能够同时实现路由和定位的综合协议OLSR-P(最优链路状态路由和定位)。该协议对OLSR协议进行了改进,能够将路由开销和定位有效结合,并对数据包结构进行改良,利用原协议的路由开销实现定位。仿真实验结果表明:OLSR-P协议不仅能够同时实现路由和定位,还能有效地控制开销。

In connection with the node position estimation and routing control in Ad Hoc networks, this paper proposes an Opti- mized Link State Routing （OLSR） protocol-based integrated protocol, i.e. OLSR-Positioning （OLSR-P） protocol, which can implement routing and positioning simultaneously. This improved protocol effectively integrates routing overheads and positio- ning procedures and modifies the data packet structure so as to implements positioning hy using the routing overheads of the o- riginal protocol. The simulation results show that the OLSR-P protocol can realize routing and positioning simultaneously and effectively control the routing overhead.
