Energy Saving Strategy In The Wireless Body Area Network

Facing with the WBAN (wireless body area network) restricts energy scene, a strategies isput forward to help to reduce the energy consumption, which contains the two points of the view:one is the opening source, the other is reducing consumption. Opening source means to find thesource of the energy around the WBAN ambient, the cutting consumption means to find a properway to reducing the energy consumption without reducing the WBAN network performance.Firstly, aiming at the energy restricts scene has become the prominent problem, we analysisthe researching state in the whole word and point out the strengths and weakness, then find out themain factors that contributes to the energy consumption in the WBAN. A concludes is drawingthat energy saving can be considered from the two aspects: Opening source and cuttingconsumption.Then combined with the real body area network application ambient, we consider finding animplementation of energy strategies to achieve good energy saving effects. Compared with all theenergy collecting technology, we analysis the energy source’s power, energy source and efficientparameters, then choosing the solar energy source as the energy source. After that we analysis thekey technology in the solar energy collection system, then we design the schematic drawing,simulate the designing schematic to see whether it fit our required, after that design the PCBlayout and test it in the real environment.From the previous studying that cutting the consumption to save the energy is also a goodchoice. By compared to the routing protocol that used in the wireless sensor network, we proposeda new routing protocol to arrive the energy balanced performance, which based on the LEACH(Low Energy Adaptive Clustering Hierarchy) protocol. In order to verify the protocol that weproposed, we simulate the routing protocol in the Matlab platform, the result is the improvedclustering routing protocol can balance the energy consumption between nodes and achieve abetter energy saving effect.Finally, combined the LEACH protocol with the energy implementation, we proposed a newprotocol that combined the LEACH and energy implementation. According to the energy consumption, we divide the node’s energy state in three states: the storage period, the stable periodand the consuming period. For different period has different feature, we have designed differentalgorithm to fit the different characteristic. We also simulate the algorithm to verify the protocoland the result shows that the protocol also is a better way to solve the energy implementation inthe WBAN.
