窄带自组网(AdHoc)的高度动态性、低速传输与不稳定传输特征,导致其路由协议的设计尤其困难,尤其是如何减少路由协议的带宽占用一直都是业界的难题。首先分析了窄带无线自组网动态路由协议的减少带宽占用量的方法及其基本工作原理,然后在一种典型的应用场景下,综合采用多种优化方法对OLSRv2路由协议进行了改进设计,并通过仿真验证确认改进后的路由协议性能有较大的提升,尤其是路由协议带宽占用量有实质性的减少,可有效提升窄带无线自组网的综合性能。

The highly dynamic,low-speed transmission and unstable transmission characteristics of the narrow-band Ad Hoc network would usually lead to extremely difficult design of its routing protocol.In particular,how to reduce the bandwidth consumption of routing protocols is always a problem for the industry.Firstly,the method and its basic working principle of reducing the bandwidth consumption of the narrowband wireless ad hoc network dynamic routing protocol are analyzed.Then,in a typical application scenario,a variety of optimization methods are used to improve the design of OLSRv2 routing protocol.Finally,the simulation indicates that the performance of the modified routing protocol is greatly improved;especially the bandwidth consumption of the routing protocol is substantially reduced,which can effectively improve the comprehensive performance of the narrowband wireless ad hoc network.
