Optimized algorithm of energy for reducing indoor electromagnetic radiation from wireless network

Conventional indoor wireless networks always adopted increasing power of sending nodes to gain better communication effect no matter horc the channel status,which augmented electromagnetic radiating and power consuming of the networks in a way.The problem about the optimum sending power of its nodes were discussed.A controling model to power of the nodes was first proposed for to minimize the sending power on the basis of ensuring effective communication.And then an energy optimization algorithm was derived for to reduce the transmitted power of wireless network nodes.Based on the clustering technology and COST-231 model of wireless sensor networks,the path loss model and minimum transmission power model of indoor wireless networks has been constructed.And,the energy optimization of network nodes has been came true.Theoretical analysis and simulation results show that the algorithm not only guarantees the effect of the original communication,but also reduces electromagnetic radiation and energy cost.
