Design for Power Control in Wireless Ad Hoc Networks

Abstract:

Analysised and researched for the power control problem in Ad Hoc network, and Proposed an improved power control protocol based on 802.11MAC layer of CSMA /CA mechanism . The algorithm increased the transmission power value and the received power threshold in the RTS/CTS control packets, the node and its adjacent node can determined the data packet transmission power and received power accorded it, Thus effectively reduced the nodes between the hidden terminal and exposed terminal interference, and can reduced the power consumption of wireless nodes. It is compared with the IEEE 802.11 MAC protocol by simulation. The results show that the power control protocol can improve the system end to end throughput performance, and minimize the power consumption of wireless nodes, so as to saved the network power consumption .
