A Study Of Multi-Path Routing Algorithm Of Wireless Sensor Networks Based On Energy Balance

Great attention is paid to the wireless sensor networks because they have such characteristics as rapid deployment and strong survivability, so they can handle the target detection, track in the specified range and complicated circumstances. But the main limitation of the sensor network is that the power carried by the nodes is limited, which results in the failure of some nodes because of their environment or energy depletion, so it can affect the survival of the entire network and the validity of the transmission. It is very important to efficiently use energy and prolong the network lifetime under the premise of limited energy of wireless sensor networks.Based on the above problem, in order to extend the lifetime of wireless sensor networks and enhance the efficiency of transmission as high as possible, a wireless sensor network model based on energy balance is designed. And a deeper research is done on its structure, transport mechanisms and organizations and multi-path routing algorithm. The main achievements of my research are as follows:(1)The paper analyses the main factors which affect energy balance of wireless sensor networks. Based on the definition of energy balance entropy, a model is made by using a double-layer topology structure. The structure is simple and easy to implement, and has the capacity to control itself in balancing the energy of network nodes.(2)As to wireless sensor network model based on energy balance, the transport mechanisms of wireless sensor networks and organizational processes is designed from three aspects:Sink centralized control, self-organizing maintenance of nodes and network reconstruction.(3)Under the premise of considering the imbalance of energy consumption in the transmission of wireless sensor networks, the AODV protocol is optimized, which avoids the hot issues and network separation problems, and broken links are easy to restore.(4)A multi-path routing algorithm is designed based on the double-layer topology of energy balanced wireless sensor network, A simulation verification and analysis are carried out in terms of availability and effectiveness of the algorithm from the aspect of energy balance, network lifetime, routing overhead and average packet delivery ratio.
