Keywords: Sensor networks, data aggregation, particle swarm optimisation, correlation coefficient, energy In this paper, we propose a routing scheme for data gathering and aggregation in wireless sensor networks. scheme utilises a heuristic algorithm to optimise data traffic and the transmission structure in terms of energy The particle swarm optimisation (PSO) algorithm stems from the simulation of a simplified society model, and it Given the set of source node S and the base station d in wireless sensor networks G(V, E), our objective is to find a advantage of data aggregation to reduce the transmission task, the SPT algorithm expends the most energy compared Fig.5(a) illustrates the average energy consumption of the four algorithms when the number of source node k=15.	./cache/work_qto5jhdf2nehzjcza67fh65wse.pdf	./txt/work_qto5jhdf2nehzjcza67fh65wse.txt
