摘要
在无线传感器网络节点上设计了一种简单有效的改进的S-MAC协议,实现了MAC协议功能模块,主要功能是建立和维护节点的激活/休眠周期,控制节点接入信道,完成数据分组的收发。测试结果表明MAC层模块能够按照设计标准正常运行,且性能良好。
In this paper a simple and effective improved S-MAC protocol was implemented on WSN node and a MAC protocol function module was built. Its main work is to establish and maintain the cycle of node activation/sleeping, control the node access channel and finish the transmitting and receiving of data package. The testing result demonstrated that the MAC layer module could run smoothly followed by the designed standard and the performance was excellent.
