摘要: 分析了传统无线网络系统模型中的能耗.利用最小能量编码(ME-Coding)作为信源编码的On/Off Keying(OOK)调制方法,对节点间传输的信号序列进行了优化,结果提高了信噪比,降低了误码率.但实验模拟仿真结果表明,当将链路能耗考虑进总体能量消耗中后,若使用传统系统模型,其总能耗并未得到优化. 因此提出并验证了更加适合最小能量法的系统模型,以便降低系统能耗和延长传感器网络节点的寿命.

Abstract: The energy consumption of an OOK transmitter was analyzed. A simple and energy efficient source coded ME-Coding On/Off Keying modulation scheme for wireless application was presented. The SNR performance of ME-Coding OOK was better than other modulation methods in a bit low rate. However, when the circuit energy consumption is taken into account, the simulation results demonstrate that the total energy consumption of the classical system model can not be reduced. It proposes a new system model which matches the ME-coding OOK communication to get the total energy optimization. 
