一个简化的无线传感器网络管理编码规则

Reduced Encoding Rule for Wireless Sensor Network Management

为降低无线传感器网络(WSN)节点能耗并延长网络寿命,基于网络管理操作原语,设计一种简化的WSN管理编码规则。根据网络管理报文的长度,选择一个或多个字节表示网络管理中协议数据单元的长度。理论分析和实验结果表明,该编码规则能降低报文的编码长度及节点的通信能耗,并提高编码效率。

In order to reduce the energy consumption for communication come from network management and prolong the lifetime of the network, this paper designs a Reduced Encoding Rule（RER） based on Wireless Sensor Network（WSN） management primitives. In RER, one byte or more bytes can be used to indicate the length of the Protocol Data Unit（PDU） according to the length of the management message. Theoretical analysis and experimental results show that the encode rule can effectively reduce the datagram length and the communication energy, increase the encoding efficiency.
