The Design And Simulation About Routing Protocols Of Wireless Sensornet Work

Wireless sensor network integration of multiple techniques,widely used in military, traffic management, environment monitoring, industrial automation production areas, The development of it more and more people pay attention to, has a very broad application prospects. It is different from the traditional wireless network, It has network node with multiple, single node limited resources and other characteristics, the routing protocol is suitable for traditional wireless networks are not suitable for WSN routing protocol, Routing protocol design must be dedicated to its characteristics.This paper is to address the problem, in-depth analysis of the routing protocol of WSN existing, especially the analysis of position based routing protocols and energy aware and hierarchical routing protocol. According to the application needs of the project of WSN, the network is mainly used for field monitoring, network involves the region scope is big, very many nodes within the network, analysis and comparison of a variety of existing WSN routing protocol, and assimilated excellence idea among them, routing protocols for WSN is proposed in this project, study the method of the protocol design. The main content:1、We study the WSN of this project, analyze the network architecture, use hierarchical structure design of wireless sensor network, including perceptual information collection layer(referred to as the acquisition layer) and distribution of information access layer(referred to as the access layer) of two layers, according to the network structure presents a layered large-scale routing protocol for WSN.2、We study the characteristic collection layer network, summarize the routing demand, refer to the existing routing protocols position and energy aware(GEAR), designe collect layer network ICNRP(Information Collection Network Routing Protocol) routing protocol, it is through the establishment of optimal path of energy efficient, transfer data from the sensor nodes to the sink node reliably.3、we study the characteristics of the network access layer, according to the characteristics of the access layer network data flow, designe the network access layer GAR(Gateway Access Routing) routing protocol. The routing protocol solve the routing problem converge to the access point, network transmission path for the rendezvous point to the access point to transmit data information.4、We study simulation on how to carry out the routing protocol in the simulation environment, design routing protocol model and the network model, simulation platform, validation in a large number of node in the case of the routing protocol.The research work of this paper is mainly based on practical application, According to the application requirements of the project and the network characteristics and requirements, reference many existing routing protocols, we design the hierarchical large-scale WSN routing protocol.It has certain innovation.
