Research Of Topology Control Algorithm In Ad Hoc Network Based On Energy Balance

With the proposal of green computing, more and more researchers begin to pay attention to the green network communication, and strive to create a green and energy-efficient network environment.Ad hoc network as a private network, its energy demand has been more widespread attention with the development.Since the energy of Ad hoc network is limited, the effectiveness of the energy is a very important work in Ad hoc network.Under the premise of network connectivity and coverage,topology control is a control technology which selects the routing node,removes redundant communication links between the nodes and optimizes the network structure through the power control.Topology Control in Ad hoc networks have a great impact on Ad hoc network performance,"good" topology can save the energy of the network nodes to extend the life cycle of the node, thereby prolonging the survival time of the entire network.In the field of topology control study,technology strategy based on energy-efficiency energy mainly concentrated on how to effectively reduce energy consumption of the node data in the process of transmission.The majority of topology control algorithm is mainly concerned about scheduling scheme of the node communication power dissipation, and ignores residual energy which impact on the network lifetime. Residual energy reflects the node energy level of supply.In Ad hoc networks,because the size of the volume of business in data forwarding traffic is different, the speed of the node energy consumption is also different.Therefore, in order to avoid producing death node early,we you need a balanced energy consumption rate of each node as much as possible.To solve this problem, we propose a energy-balanced-based toplogy control algorithm(EBBTC).To balance the energy consumption rate,the algorithm consider the inter-node communication energy consumption and residual energy of nodes in the building topology.In addition, EBBTC algorithm set up a balancing factor which reflect weight ratio of the transmission power and residual energy during the node link task. In addition, the balance factor can control the power of the node energy consumption rate and assigned to evenly distributed the entire energy consumption to each node in Ad hoc network which makes the life cycle of the node close to the entire network life cycle and reduce network energy consumption, improve the overall network lifetime.Compared by Maxpower and LMST algorithm,simulation results show that EBBTC has certain advantages extend the network life cycle and improve throughput performance. Meanwhile,the experiment simplely estimates the balance factor.Prove that when=0.5,energy consumption level of different nodes in the network is less which balances the energy of all nodes of the network speed and extends the network lifetime.
