Deterministic cluster head selection for wireless sensor networks

Abstract

The applications and adoption of wireless sensor networks (WSNs) in social and environmental purposes are increasing because of monitoring different infrastructures such as military, scientific, environmental, and domestic infrastructures. Low energy adaptive clustering hierarchy (LEACH) and its variants use some intermediate nodes, known as cluster heads, for relaying the communications made between the sensor nodes and the base station. These schemes, however, lack of a deterministic cluster head selection technique to form a certain number of required clusters. In this paper, we propose a deterministic cluster head selection technique to select expected number of clusters. Simulations justify the mathematical modeling of such a cluster head selection scheme which can be applied directly in realistic systems.
