Load Balancing And Congestion Trends Of The AODV Protocol Improvements

MANET (Mobile Ad Hoc Network) is composed of wireless mobile nodes, without relying on existing fixed network infrastructure and can quickly be put into use, each network node to collaborate, communicate via a wireless link, sharing information and services, network nodes dynamically and randomly join the network and exit the network.In MANET, nodes frequently move, join and exit the network must lead to dynamic changes of network topology, routing problems become critical and difficult in MANET research and applications. AODV protocol is a relatively good agreement, there are fewer routing overhead and better performance than other Ad hoc network routing protocols. But this agreement in the larger network load conditions, the effect is not very satisfactory, its network performance decreases rapidly. So for this paper, proposed a improvements protocol LBCT-AODV based on load balancing and congestion trends degree.First, the article introduces the significance of the topic, research background, as well as research in motion and abroad, and describes the arrangement of sections of this article.Second, it introduces the concept of Ad hoc network, the mainstream routing protocol and AODV protocols.Again, propose a new improved protocol LBCT-AODV based on AODV protocol, load balancing and congestion trends degree.Finally, Comparison and analysis of the experimental results by NS2network simulation software.This article implemented and simulated LBCT-AODV protocol on NS2network simulation software, by analyzing and comparing the simulation results of LBCT-AODV and AODV prove when the network load increases, LBCT-AODV protocol can effectively improve the packet transmission rate, reduce end-to-end delay, increase network throughput, thereby improving the overall performance of the network.
