Research On Routing Technologies In Heterogeneous Network

In recent years, development of computer networks and communication technology advances, colorful variety of wireless network technology has been applied to all areas of social life.Many new heterogeneous networks appears which using different networking technologies,such as WLAN, WiMAX, WMN, WSN, Ad Hoc networks,3G networks and LTE networks,,and the appearing of Wireless and wired heterogeneous network convergence technologies,they all have brought profound changes to people’s ordinary social life. Ad Hoc network is composed of a set of movable nodes,these nodes come with a wireless communication transceiver,constructed by these mobile nodes into a wireless network who has features of multi-hop, no center, self-organizing, self-healing. As the Ad Hoc network has a great advantage in the field of heterogeneous network convergence, the study of it will have a very important academic significance and application prospects.Heterogeneous networks is coupling the different network together with the configuration of a heterogeneous network will become a homogeneous network. Heterogeneous network research focus on how is that different network coupling,how to achieve in heterogeneous network routing lookup optimization,this will be a very important research topic, but also the focus of this study.This paper outlines a heterogeneous Ad Hoc network routing protocol’s production, characteristics and key technologies, detailed study and analysis several typical Ad Hoc network routing protocols,and at last emphasis our energy on the AODV protocol. Second, on the basis of research AODV routing protocol, discuss the integration of heterogeneous networks technology, research in-depth on heterogeneous network topology,and divide a heterogeneous network topologies into two pieces,one is simple heterogeneous network mode,the other is complex heterogeneous network mode. Finally, based on their inherent characteristics of the network topology,we propose two routing protocol based on relay models,there name are ARSHN and ARCHN, at lastdo testing and simulationforrouting procedures.The main advantage of ARSHN routing protocol:1. The protocol path selection process is based on relay patterns.each network is independent, low coupling, only the gateway nodes interact. And gateway routing node relay can speed up the routing process and effectively reduce the delay.2. The single network itself is equivalent to an Independent system, different network choose the best routing path according to their own characteristics.The main advantage of ARCHN routing protocol:1. In the complex heterogeneous networks,a Independent network may have multiple network export destination network node, and choose the best path to a gateway work status using anycast routing function.2. Complex Independent network supports automatic routing parameters adjustment.
