摘要： 针对MAC协议无法解决节点能耗和网络性能之间矛盾的问题，在AS-MAC协议的基础上，基于跨层的方法提出CLR-MAC协议。该协议利用路由层的路由表信息改变AS-MAC协议的控制帧格式，解决AS-MAC协议中因“强迫唤醒”造成的能量浪费问题，以延长网络寿命。理论分析和仿真实验证明，该协议随网络密度的增加，节能增益呈线性增加。

Abstract: In order to eliminate the conflict between node energy consumption and network performance for Medium Access Control(MAC) protocol in single-layer network, this paper designs an energy efficient protocol named CLR-MAC based on AS-MAC. It uses the information of routing layer for MAC layer and modifies the control frame of AS-MAC to solve the compulsory wake-up problem. Through performance analysis and simulation, CLR-MAC protocol is linearity elevation along with the increasing sensor density.
