A Position-Based DSR Algorithm for Ad Hoc Networks
Guanghui Zhu · Computer Technology and Development · 2007
Traditional DSR routing protocol always transmits information to all consecutive nodes,so when much routing requests occur,it is easy to induce that some nodes with inadequate energy and even the network breaks down.Otherwise when selecting final routing,it doesn't consider fully mobility of the whole link circuit,therefore it mustn't be the optimum.This paper presents a Position-Based-DSR Algorithm(PBDSR) improved on DSR routing protocol.PBDSR makes up a zone with the node's position information for selecting router,and replaces the greedy transmit mechanism of DSR,uses the collectivity distance of the chain and mobile parameter as the weight of router selecting.Ultimately it can help to select a best router for saving energy thereby improving the survival period and stability of the Ad Hoc net effectively.
