无线异构Mesh网络搭建与负载均衡路由研究
Study on Wireless Heterogeneous Mesh Network Construction and Load Balanced Routing
摘要
Abstract
In application scenarios such as smart cities,a single wireless communication technology cannot cover complex network environments,while different communication technologies cannot communicate with each other,making it impossible to take full advantage of different wireless communication technologies.Therefore,we design a device that can communicate with multiple wireless communication nodes,which is called wireless heterogeneous communication modules(WHCM).WHCM is used as a hub to build a communication heterogeneous mesh network(CHMN).CHMN consists of nodes with multiple wireless communication protocols.We propose an AD HOC on-demand multi-path distance vector(AOMDV)routing protocol based on CHMN networks,named CH-AOMDV.CH-AOMDV is able to identify different types of communication protocols during the route initiation and path establishment process.It can also identify the communication distance,data transmission rate,energy and the load capacity of each node in CHMN.Simulations with NS-2 show that the performance of the CHMN is better than that of the traditional network when the distribution density between nodes is higher in terms of packet delivery rate,average end-to-end delay,throughput rate and routing overhead.This work proposes a new method of implementing CHMN and the corresponding routing protocol CH-AOMDV.The proposed protocol is superior to the other three protocols,improves network lifecycle,throughput and packet delivery rate,and reduces node overhead and average end-to-end delay.The protocol is useful for CHMN.关键词
