Abstract
One of the major constraints of wireless sensor networks is limited energy available to sensor nodes because of the small size of the batteries they use as source of power. Clustering is one of the routing techniques that have been using to minimize sensor nodesโ energy consumption during operation. In this paper, A Novel Clustering Algorithm for Energy Efficiency in Wireless Sensor Networks (ANCAEE) has been proposed. The algorithm achieves good performance in terms of minimizing energy consumption during data transmission and energy consumptions are distributed uniformly among all nodes. ANCAEE uses a new method of clusters formation and election of cluster heads. The algorithm ensures that a node transmits its data to the cluster head with a single hop transmission and cluster heads forward their data to the base station with multi-hop transmissions. Simulation results show that our approach consumes less energy and effectively extends network utilization.
Highlights
Recent advances in communication technology have led to the development of intelligent, lightweight, low cost sensor nodes that cooperatively collect data from the place of deployment [1]
During the set-up phase, sensor nodes are organized into different clusters based on the received signal strength and cluster heads are selected for each cluster as routers to the base station
In order to evaluate the performance of our new clustering algorithm (ANCAEE), we simulated Low Energy Adaptive Clustering Hierarchy (LEACH), TL-LEACH protocol and ANCAEE using MATLAB
Summary
Recent advances in communication technology have led to the development of intelligent, lightweight, low cost sensor nodes that cooperatively collect data from the place of deployment [1]. There is a need to minimize energy consumption in WSNs. In recent time, many clustering algorithms have been proposed with different protocols. During the set-up phase, sensor nodes are organized into different clusters based on the received signal strength and cluster heads are selected for each cluster as routers to the base station This algorithm saves energy, since only CHs are allowed to transmit data to the base station rather than all nodes. The main goal of the protocol is to use non-homogenous sensor nodes to distribute energy uniformly in WSNs. The protocol operation is similar to LEACH protocol, apart from method of cluster head selection is based on two different levels of energy. Subsequent CHs are elected using this process This approach ensures that CHs are randomly selected and energy consumption is uniformly distributed among sensor nodes. The main objective of our research work is to develop an algorithm that will minimize communication distance among sensor nodes and prolong network utility
