中文摘要: 节能是无线传感器网络的研究焦点之一,设计能量有效的MAC策略是达到节能目的的一种有效手段。本文结合无线传感器网络中一种节能MAC协议——BMA,引入协同分集技术,提出了一种新的协同MAC协议——CD-BMA。分析和仿真表明,所提协议能够显著提升系统的容量及能量效率等方面性能。
Abstract:In wireless sensor networks, energy efficiency mechanism is a key problem. One way to reduce power consumption is designing energy efficient MAC protocols. In this paper, we combine the BMA protocol with cooperative diversity techniques, and propose a new MAC protocol which is called CD-BMA. Simulation results show that the proposed protocol can obtain better performance in capacity and energy efficiency.
