“…That is, the CH should have both high residual energy and reasonably low intra-cluster communication cost. In our previous work, we proposed an energyefficient cluster-head selection protocol (ECHS) to find out these suitable CHs [17]. In ECHS, the temporary clusters (TCLs) to calculate and compare the thresholds in different TCLs, as shown in (2), which evaluates the lifetime of the cluster.…”

As one of the most dominant factors in clustered wireless sensor networks (WSNs), the selection of cluster-head (CH) can impact the network performance. The selection shall be subject to at least two factors. (i) The number of CHs may vary in different periods of the WSN lifetime. And (ii) this number can determine on the performance, in terms of energy consumption and WSN lifetime, etc. In this paper, we draw attention to the randomly deployed WSNs based on the independent homogeneous Poisson process, and propose an Improved Cluster-head Selection (ICS) approach. Firstly, we optimize the dynamic number of CHs. Then we obtain the suitable CHs via the improved selection procedures based on three selection phases by introducing the temporary clusters. Meanwhile, CECCbased (Common Energy Consumption Cycle) synchronization is used to coordinate the intra-/inter-cluster communication. ICS saves the energy consumption and prolongs the network lifetime.Simulation demonstrates the enhanced network performance.
