Title
Multihop Transmission Strategy to Improve Energy Efficiency in WSNs
Abstract
Many researches have shown interest in the development of energy efficient transmission technique to reduce the power consumption and to extend the network lifetime. In this paper we propose an energy-efficient multihop transmission strategy in Wireless Sensor Networks (WSN). We consider a clustered WSN where each cluster is composed of N sensor nodes. These last detect information and try to transmit it to the cluster head which is responsible for transmitting received data to a center of maintenance in order to take the appropriate intervention. We suppose that the transmitting symbol is correctly received only if the Signal-to-Noise Ratio (SNR) at the receiver is above a threshold γ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sub> . The main objective of our work is to define a new transmission technique minimizing the power consumption using multihop communication. The selected relays which participate in this transmission are those offering the least transmit power while maintaining SNR equal to the threshold γ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sub> . Therefore the proposed transmission technique can reduce enormously the power consumption compared with direct transmission and the transmission with a single relay. Simulations results demonstrate that our proposed strategy significantly reduces the energy consumption, thus confirm significant energy relative to direct transmission.
