摘要

无线传感器网络MAC层协议低功耗侦听(LPL)使用较长的前导码

在密集部署的无线传感器网络中造成较大的"串音"开销。提出一种智能低功耗侦听协议(SLPL)

通过在前导码中嵌入目的地址和前导码长度索引

能有效降低非目的节点的串音开销

减少目的节点的接收开销。理论分析和部署测试表明SLPL的能效比LPL有显著提高

同时测试显示SLPL功耗小于X-MAC协议。

Abstract

As a representative MAC for wireless sensor networks

low power listening（LPL） used a long preamble in each transmission and caused significant overhearing cost in a dense deployment.To save such cost

a new MAC protocol-smart low power listening（SLPL） was proposed by embedding destination address and preamble index into the ordinary preamble.Both the theoretical analysis and the deployment test show that SLPL outperforms LPL in power efficiency.The test also shows that SLPL saves more power than X-MAC.
