Step-by-step approach for energy-efficient wireless sensor network

Abstract

Energy minimization has become a key factor for efficient data transfer in wireless sensor network (WSN). IEEE 1451.5 standard explores the wireless communication schemes between multiple sensors and a data gathering node (DGN) emphasizing the multiple input single output (MISO) structure. In this paper, an energy-efficient cooperative technique which is done using distributed computing is proposed for a WSN. Selected numbers of sensors are used here to form a MISO structure wirelessly connected with a DGN. The selection of nodes is based on a step-by-step selection procedure where residual energy and channel gain parameter play the key role in selection. Data are sent by the sensors to a DGN using a multihop transmission. Energy models are evaluated for both correlated and uncorrelated scenarios while energy efficiencies are compared for different combination of cluster size and selected number of sensors. Delay difference is also derived. (IUT) as a faculty on 1999 and is currently serving as a full professor.

An Efficient Data Collection Protocol Based on Multihop Routing and Single-Node Cooperation in Wireless Sensor Networks

“…It adopts the cross-layer method with the combination of cooperative MIMO, multihop routing, and hop-by-hop data recovery mechanism. In order to further reduce the control overhead and the protocol complexity, a method implementing the communication between remote cluster heads nodes through MISO technology has been mentioned in [14]. A plurality of transmitting nodes at the sending end is used to achieve cooperative transmission, but, at the receiving end, there is only one node for receiving.…”
