Improvement of Less Packet Loss S-MAC Protocol for Wireless Sensor Networks
Lun Yu · 2011
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 enhances the network throughput.
