| Abstract: | Aimed at the character of energy limitation of wireless sensor networks,to solve this problem,an improved AODV protocol based on power control is proposed.The position of current node and next hope node is added to the route requesting message,the right transmission power level in the microchip is selected to send the packet through calculating the optimum transmission power,energy mini-mization is used in packet transmitted.The simulation shows that the improved AODV protocol effectively improve energy uti... |
