无线传感器网络节点MAC层的优化

Optimization of wireless sensor network nodes MAC layer

采用计算机网络协议中分组交换的时间片概念,根据网络规模和数据量大小,对网络设置具体的唤醒时间和休眠时间,从而优化了MAC协议.实验表明,优化后的网络具有固定的时延、较低的丢包率和较长的寿命.

Using packte switching time slice concept of computer network protocol,according to network scale and data and setting network specific wake-up time and resting time,the MAC protocol was optimized.Experimental results showed that optimized network had specific fixed delay,low packet loss rate and loger life.
