摘要
当前无线传感器网络的MAC层编址技术利用哈夫曼编码的方案缩短了平均地址长度,但需要几轮协商过程。基于网络分簇结构的方案结构清晰,但地址分配不公。基于地理位置信息的方案有助路由,但高精度的位置信息难以获得。针对上述问题,在分析无线环境下地址复用原理的基础上,给出几种典型方案,比较其性能差异和适用范围,给出动态编址需要解决的问题。
In Wireless Sensor Networks（WSN） MAC addressing technologies currently,the schemes using Huffman code short the average address length while in need of several negotiation.The schemes based on cluster structure of networks have clear frames but with unfair address assignment,and that based on geographical location information can provide assistant to routing while the precise location information is hard to achieve.Based on the analysis of address reuse principle,this paper enumerates several representative schemes and compares their performance diversities and application area.
