Location information based data aggregation routing algorithm in WSN

Under the applications background of wireless sensor network(WSN) in the construction environment,and according to the characteristics of wireless data transmission network in building energy consumption monitoring system,the nodes in the designed network are clustered based on location information,and a two-tier architecture model of this network is established.Then the location information based data aggregation routing algorithm in WSN which is appropriate for this model is designed.It ensures that the cluster head node can select the best next hop cluster head node from the neighbor list,and achieve data communication with the Sink node.The simulation results show that the designed routing algorithm has advantages of low delay,high reliability and energy saving.
