Research On Multi-hop Wireless Sensor Network Routing Strategy Based On Zigbee

With the development of the physical network, wireless sensor network has been a hot topic in physical network technology research, which supported by Zigbee technology. With the main characters of self organization and high network capacity, wireless sensor network based on Zigbee has applied widely, such as industrial control, intelligent household and other fields. What’s more, with the perfection of Zigbee technology and propulsion of physical network,it would be used in more and more application. But the wireless sensor network generally is powered by battery, so battery life determines the network life, therefore the energy saving of wireless sensor network based on Zigbee research becomes important research subject.This paper improves Zigbee wireless sensor network layer routing algorithm to minimize energy consumption below the premise of delivery ratio, which made it possible to achieve better energy-saving effect.Firstly, this paper introduces the wireless sensor network routing algorithms, the advantages and disadvantages to the actual application environment.But the algorithm is more complex, it is not suitable for Zigbee network.algorithm has problem of broadcast flood, energy consumption inequality,routing out still maintenance and so on. After proved repeatedly, this paper puts forward the improved AODVjr algorithm. By setting parameters of the radio broadcast to avoid flood inundation, using the minimum battery energy consumption algorithm to balance node power and replying confirmation to ensuer delivery,the necessary routing was deleted. Through to the improvement of the AODVjr algorithm and AODVjr algorithm simulation contrast found that the improved algorithm effectively delays the network segmentation of the time delay in the network life.
