一种适合太赫兹纳米传感网的多跳路由协议
无线纳米传感器网络是一种新型的传感网，网络中的纳米节点可以在太赫兹带通信。目前对太赫兹纳米传感网的研究主要集中在物理层，而对路由协议方面的研究较少，因此提出一种基于网络状况的多跳路由协议。该协议限制了候选节点的区域，保证多跳转发的方向；考虑了太赫兹信道的特性，建立链路代价函数以权衡传输能耗、信道容量和传输距离；以一定的概率在多个代价最优的节点中选择下一跳节点，从而延长网络的生存期。仿真结果表明，所提出的路由协议具有吞吐量大和能耗低的特点，适合作为太赫兹纳米传感器网络的路由协议。...

| Bibliography: | nanosensor networks ; Terahertz ; muhi-hop routing ; molecular absorption ; channel capacity Wang Zhiyu, Xu Juan （College of Electronics and Information engineering, Tongji University, Shanghai 200092, China） 11-2305/TN Wireless nanosensor networks are novel networks and nanonodes in the networks can work in Terahertz band. Researches are mainly focused on physical layer; however, study of routing protocol in this field is still in an initial stage. Consequently, a novel multi-hop routing protocol based on network conditions is proposed. In our routing protocol, the area of candidate nodes is narrowed in order to control the direction of multi-hop forwarding. A link cost function is established to trade off energy consump- tion, capacity and distance, taking the peculiarities of Terahertz channel into consideration. Several nodes with low link cost have the probability to be selected as a next hop, which prolongs the lifetime of nanosensor networks. Simulation results show that the protocol we proposed can achie |
