Research WSN's Dynamic Routing Algorithm Based On Beacons

WSN can collect monitoring area of all kinds of information by sensor nodes,sensor nodes deal with initial information,and through the wireless communication transmission to the user.Due to the sensor node is small,so computing power,communication skills,and carrying energy is limited,each node can only obtain the local network topology information,its running on the network protocol is not too much complicated.The paper designs a kind of dynamic routing protocol of wireless sensor based on beacon frames,make sensor nodes lower energy consumption,and energy consumption uniform,in order to prolong the life cycle of the whole network,and through the OMNeT++ simulation.The main work and results are as follows:(1)To know the status of WSN at home and abroad,putting forward a dynamic routing algorithm of WSN based on beacons and its meaning.(2)Analyzing the theory of several kinds of wireless sensor network routing protocol system,to explore the characteristics of different routing protocols.(3)According to the characteristics of the wireless sensor network routing protocol,to design based on the beacon frame of on-demand routing algorithm,and the simulation model set up,using OMNeT++ software simulat experiment.(4)According to the simulation model gets data,linear fitting to get empirical formula,and put forward the theoretical guidance for the application of the scene.(5)With CC2530 platform that made by TI,developing the routing protocols of wireless sensor network node and its system,and through debugging to run.
