Energy-Efficient Routing in Wireless Sensor Networks Based on Data Reduction.
Vasu Jolly, Shahram Latifi, Naoto Kimura · 2006
A simple technique is presented to reduce power consumption in wireless sensor networks. This technique is based on reducing data size and sending smaller size packets which will in turn result in power savings. Target applications are assumed to involve environments where variations in data are typically continuous in time. Experimental analyses show that the energy saving can be up to 50 % if the proposed technique is employed. Further, energy saving grows linearly with the number of hops between the source and sink nodes. In a sensor network tiny sensor nodes have a capability to sense and process sensed data, and perform communication among them [1, 2]. Typically these nodes are deployed in a large sensor field. Each node in a sensor network plays the dual role of a data originator and data router. Sensor nodes are prone to failure, and therefore the sensor network topology changes frequently. If a few nodes die, this may cause
