Title
Energy-Efficient Transmission Strategy with Cluster Organization Phase to improve Energy Saving in WSNs.
Abstract
Recently, Wireless Sensor Network (WSN) has drawn serious attention to the researchers. The most important challenge of WSN is how to extend its lifetime. In this paper, we propose an energy-efficient multihop transmission strategy with organization cluster phase. During this phase, we try to choose the cluster head node which allows communicating with the other nodes with possible minimum energy and classify the remaining nodes into two groups. We consider a WSN organized into clusters, each cluster is composed of N sensor nodes classified as follows: source node, elected CH node as the destination, group of active nodes and group of sleeping nodes. When a source node detects relevant information in the network, it tries to transmit it to the cluster head via a cooperative or non-cooperative transmission. The transmission is supposed to be correct only if the Signal-to-Noise Ratio (SNR) at the receiver is above a threshold ath. The main objective of our work is to define a new transmission technique minimizing the power consumption. It is a multihop transmission technique where the selected relays which cooperate in the transmission are those offering the least transmit power while maintaining SNR equal to the threshold ath. Therefore the proposed transmission technique can reduce enormously the power consumption compared with direct transmission and the transmission where the CH node is chosen randomly within the cluster. Simulations results demonstrate that adding an organization cluster phase before transmitting data significantly increases the energy savings.
