| 摘 要： | 针对S-MAC协议的层间丢包问题,利用缓存队列原理提出了一种简化通信数据分组格式的S-MAC协议优化改进方案。结合TinyOS的主动消息机制在Mica2节点上实现了改进的S-MAC协议,并对MAC层的丢包率进行了测试。实验测试结果表明,优化改进后S-MAC协议较标准S-MAC协议在MAC层的丢包率上有明显的降低,提高了网络性能。

| Abstract: | According to the packet loss problem in S-MAC protocol,this paper proposed an optimized scheme which based on the cache queue principle and simplified the format of group data for S-MAC protocol.Combined with the Active Message(AM) mechanism of TinyOS,the S-MAC protocol has been implemented on the Mica2 motes,and it has tested the packet loss ratio of MAC layer.The result demonstrates that the improved S-MAC protocol has significantly reduced than the original S-MAC protocol in the packet loss ratio and enh... |
