Wireless sensor networks due to real-time processing complex environment within the specified range target detection and tracking , with rapid deployment , survivability , and other characteristics and attention, but the most important for wireless sensor network node carries power limitation is limited , this causes some nodes due to environmental or energy depletion and failure, which can seriously affect the lifetime of the entire network and data transmission effectiveness , so how limited energy in wireless sensor networks under the premise of efficient use of energy and prolong the network lifetime is particularly important . Based on the above issues, in order to extend the lifetime of wireless sensor networks , and maximize the effectiveness of transmission , is designed based on wireless sensor network energy balance model , and the model structure , transport mechanisms and organizations multipath routing algorithm for a more in-depth research, the main research work and achievements in the following areas : ( 1 ) analysis of the impact of wireless sensor network energy balance of the main factors in the definition of entropy energy balance , based on the use of two-tier structure designed based on wireless sensor network energy balance model, which is simple in structure , easy to implement, has a balanced network node energy self-control . ( 2 ) For the energy balance based wireless sensor network model, centralized control from the Sink node self-organizing maintenance and reconstruction of three aspects of network design based on energy balance of the transport mechanism for wireless sensor networks and organizational processes. ( 3 ) In considering the energy balance in wireless sensor network routing uneven energy transmission factor present in the premise of the AODV protocol has been optimized , thus avoiding hot spots exist AODV protocol and network separation problems , and easy to restore broken links . ( 4 ) the design of a double-layer energy balance in wireless sensor network topology under the multi-path routing algorithm , and from the energy balance, network lifetime , the average routing overhead and packet delivery ratio and other aspects of the availability and effectiveness of the algorithm conducted a simulation and analysis.
