A Survey of Power Control in Ad Hoc Wireless Networks
Qing Wang · 2004
With the development of wireless communications,mobile ad hoe networks without any established infrastructure or centralized administration are spreading from military areas to lots of civilian areas, for example wireless office local area networks,home device networks,sensor networks and so on. With the nature of flexibility and convenience,wireless communications are supported by batteries,but battery technology is not likely to progress as fast as computing. Hence,battery power becomes a constrained resource. It is easy to know power control is an important issue. Power control can be categorized as follows: transmission power control ,power aware routing, and low power mode. First,with emphasis,this paper compares the similarities and differences of some typical algorithms of different layers about transmission power control. Moreover,it analyzes some unsolved problems that are believed to be of great interest.
