AB  - Clustering is considered as one of the life increasing approaches in wireless sensor networks. The
size of cluster head, cluster number and cluster selection is of the most important factors in clustering.
Increment in cluster size leads to distance enhancementand early discharging. The decrement of cluster size
leads to increase in overhead of controller data transport. Unsuitable selection of cluster heads results in
increase of distance to cluster members and other clusters heads. In this research, we investigate the increase
in life time of angular clustering by using dual-head cluster in wireless sensor networks in mobile sink mode.
The selection of cluster head in this approach is a function of remained energy, mean distance to members and
the gap between current cluster head and the previous one and also the distance it has with current sink. In this
method, new cluster head is not substituted by previous cluster head until performance of the current cluster
head is not less than optimum limit. Also once the optimal mean energy of the neighbor clusters of the current
sink reaches to the threshold; it is the time to displacement of the sink to another position. The results show
that this proposed approach leads to life increment.
