） Abstract： Through the analysis of the advantages and disadvantages of traditional clustering algorithm LEACH, this paper proposes an Weight and Fitness-based Energy-Efficient Clustering routing Algorithm for WSN(WF-EECA)
In the cluster-heads selection mechanism , weight factor W is introduced as adjusting parameter to choose cluster-heads,and AHP (Analytic Hierarchy Process, the AHP) is also citied to work out weight coefficients; In the attribution mechanism of non cluster-head node ,the clustering clustering factor F is introduced, considering cluster-head's factors of remaining energy, distance between cluster-head and base station and nodes; Meanwhile, weight is also used in the data transmission between cluster-head and base station, by the way of multi-hop and single-hop instead of single-hop
The simulation result shows that this algorithm effectively reduces the communication energy consumption and achives an obvious improvement on the network lifetime
