Research On Cooperative Routing With Energy-saving Technology For Wireless Networks

Cooperative routing technology is an important innovation, but also the recent research focus in wireless networks. Compared with the traditional routing technology, cooperative routing technology can be used to saving energy. This paper mainly focus on energy balance and network lifetime in node energy constrained wireless network.Firstly,the paper propose a power allocation algorithm to maximize the network life cycle, the algorithm fully take the residual energy and channel state information into account during cooperative nodes transmit power control, optimized to achieve energy saving transport, and extend the network lifetime.Based on this scheme,a cooperative routing algorithm to maximize the network lifetime is proposed. The simulation results show that the cooperative routing algorithm can effectively save energy transmission network to extend the network lifetime.Then, the paper take power distribution and collaboration node selection strategy into consideration, and propose a cooperative routing technology based on minimization of network transmission energy consumption. The algorithm mainly consider the remaining energy, channel status, energy consumption and other factors, by choosing the candidate node residual energy and more focus and channel status node as a good cooperative nodes, these nodes relative to other nodes collaborate effectively balance node energy consumption.The simulation results show that the energy consumption of the junction cooperative routing algorithm can effectively balance the network transmission nodes, to extend the network lifetime.
