Ad Hoc Network Of Independent Multi-path Routing And Improvement

Wireless network was becoming more and more important in the field of communication science since 1970s. It can be categorized into two: one is center-controlled network such as Wireless Local Area Network, the other is self-organized wireless network with no access points such as Ad hoc network. The Ad hoc mobile wireless network is receiving increasing attention and application due to its mobility and convenience it can provide to people.Wireless Ad Hoc Network owns some characteristics like self-organization, multi-hop and a frequently-changed topology. The uniqueness of Wireless Ad Hoc Network makes it impossible to adopt the technologies utilized in traditional networks. So some new protocols and technologies need to be developed specially for Ad Hoc network on channel access, network security and routing. Various routing protocols that are tailored to ad hoc networks have been put up in recent years by researchers around the world and related analysis are being down from different aspects. We focus on the routing protocols and algorithms of Ad Hoc network in this paper, and we chose the multi-path routing techniques as our main research point.This paper first introduces ad hoc network and it's routing protocols, especially explains the differences between single-path routing protocol and multi-path routing protocol, the defferences between independent multi-path routing algorithm and normal multi-path routing algorithm. Then the author proposes a simple independent routing algorithm based DSR protocol.Using a network simulation tool, the author realized the new proposed routing algorithm SIMR. This paper compares the performance of SIMR with that of ordinary DSR multipath protocol. In many scenarios we simulated, SIMR is more efficient than DSR.
