摘要:

无线纳米传感器网络是当前纳米技术相关的研究热点之一.纳米传感器可存储的能量极为有限,能量有效性是无线纳米传感器网络中必须优先考虑的重要问题.针对无线纳米传感器网络,综合考虑传输能耗和接收能耗,建立能耗模型;提出通信能耗最小化编码(EMC)方法.使用EMC,可以最小化传输能耗,可以满足码字长度和码率约束要求,可以确定最小化通信能耗的优化码长.通过实验对比分析,EMC方法在能耗方面具有较好的性能.

关键词: 无线纳米传感器网络, 通信能耗, 码长, 开关键控调制

Abstract:

For the time being,wireless nanosensor networks(WNSNs) is a research focus of nanotechnology.Because the nanosensors' energy is extremely limited,the energy efficiency is an important issue in WNSNs.By jointly taking into account the energy consumption of transmission and reception,the energy consumption model and energy minimization coding(EMC) are proposed for WNSNs.In this way,the transmission energy minimization can be achieved,the codeword length and code rate constraints can be met,and the optimum codeword length for the communication energy minimization can be determined.Through comparative analysis,the energy efficiency of EMC is better.

Key words: wireless nanosensor networks, communication energy consumption, codeword length, on-off keying modulation
