Zusammenfassung
In recent years, wireless sensor networks (WSNs) have gained increasing attention from researchers and
scholars. One of the major issues in wireless sensor network is developing an energy-efficient clustering
protocol. Hierarchical clustering algorithms are very important in increasing the network’s life time. Each
clustering algorithm is composed of two stages, the setup stage and steady stage. The most important point
in this algorithm is cluster head selection. Cluster head selection is important because, a good clustering
guarantees energy efficiency and load balancing in the network. For load balancing in WSNs, network
overload should be removed from the weak nodes (nodes with lower residual energy) and transmitted to the
more powerful nodes. In this paper weak nodes decide which node become cluster head. Weak node choice
cluster head based on node’s weight. This weight is combined of residual energy and distance. Finally, the
simulation results demonstrate that our proposed distributed clustering approach is more effective in
prolonging the network life-time compared with LEACH.
