UWB技术在DT-MSNs中的应用

Application of UWB technology in DT-MSNs

容延迟移动传感器网络(DT-MSNs)是将容延迟技术引入到无线传感器网络(W SNs)而产生的新兴网络模型。它具有节点移动,网络密度稀疏、非持续连接等特点。针对DT-MSNs方法这些特点,分析了其底层基于传统窄带通信所面临的问题,提出了将超宽带(UWB)技术应用到DT-MSNs中的想法,利用UWB的高传输速率、低能耗、高抗干扰能力,提高DT-MSN中的数据传输能力,改善网络性能。采用DCC-MAC协议到已有的DT-MSNs仿真实验平台,通过仿真实验证明:将UWB技术应用在DT-MSNs中是可行的。

Delay-tolerant mobile sensor networks （DT-MSNs）is a new network model by introducing delay tolerant netwoks（ DTN ）into wireless sensor networks. Nodal mobility, sparse network density and intermittent connectivity are its main features. Through analyzing the problem of the DT-MSNs＇s bottom protocol based on traditional narrowband communication, an idea of using ultra wide-band （UWB） technology into DT-MSNs is proposed. UWB has the features of high transmission rate, low energy consumption, high anti-interference capability which can improve data delivery ability and network performance in DT-MSNs. In order to verify the correctness of the idea, DCC-MAC protocol is added to the existing DT-MSNs simulation platform. The simulation experimental result proved that using UWB technology in DT-MSNs is feasible.
