The Research Of Link State Routing Algorithm In Ad Hoc Network

Mobile Ad Hoc Network is a new wireless network which is not based on solid infrastructure, itis flexible and quite different from traditional wired network and wireless LAN, it is easy to creatand convenient to move, so it can cover the shortage of honeycomb network and traditional wirelessLAN.There are two major class of route protocol in Ad Hoc network, one is pro-active route protocol,and the other one is re-active route protocol. We always use OSPF as the primary route protocolin our traditional wired network.OLSR which is the abbreviation of open shortest path priority belong to link-state route protocoland pro-active route protocol as well. It derive from the algorithm of traditional wired link stateroute protocol, this protocol release its route message by broadcast periodically and maintain anroute table for the path to other nodes.This paper abstract the architecture of Ad Hoc network, study the route protocol which can beapplied to this special network, analysis exist problems of link state route protocol in Ad Hocnetwork, emphasis OLSR route protocol. Base on OLSR, modify its cost by only hops, consider theenergy the node have, and then finish the final route table. Finally, to a certain degree, we find thatthis method can improve the performance of Ad Hoc Network through imitation by NS2software.
