An Efficient Ad-Hoc Routing Using a Hybrid Clustering Method in a Wireless Sensor Network

The routing methods which used in the wireless sensor network deal with the clustering method to diminish the amount of data transmission from the energy efficiency view. However, the clustering methods cause several problems in energy consumption at the cluster head node. Dynamic clustering is a method which used to supplement a high energy consumption problem by distributing energy consumption through the re-selection of the cluster head node. But, this method changes cluster structure every time the cluster head node is re-selected, which causes energy consumption. Namely, the dynamic clustering method approaches examined in previous researches involve the repetitive processes of cluster head node selection. This consumes a high amount of energy during the set-up process of cluster generation. Consequently, this paper proposes the hybrid clustering method that fixes the cluster and selects the head node in a round-robin method. The hybrid clustering approach is an energy-efficient method that realizes consistent and balanced energy consumption in each node of a generated cluster to prevent repetitious set-up processes as in the LEACH method. The propriety of the proposed method is substantiated with a simulation experiment.
