摘要
在地理位置信息的基础上,提出一种双信道功率退避的AdHoc网络节能方案。基本思想是控制信道功率由大到小退避,数据信道功率由小到大"退避"。并利用地理位置提供的便利,较好地解决了链路的不对称问题。此外,介绍了功率退避算法,简要分析了成功传输的概率。仿真结果表明,该协议能够满足AdHoc网络近距离节点优先通信的设计需求。
In this paper,an energy optimization with dual channel power controlled backoff based on geographic location is proposed. The basic idea is control channel backoff from low power to high power, data channel ＂backoff＂ from high to low. And using the benefit of geographic information,the problem of asymmetric links is solved better. In addition backoff algorithm is introduced and the successful transmission probability is analyzed briefly in this paper. The simulations result shows it can meet the design of Ad Hoc networks of short distance priority.
