In the lossy wireless sensor network (WSN), packets loss can severely degrade the performance of data gathering algorithm based on compressive sensing (CS). Due to the limited retransmission cannot ensure the high reliability of the wireless link, the CS data gathering algorithm based on retransmission and temporal sequence correlation prediction (CS-RTSC) is proposed in this paper. When packets loss...

Wireless Sensor Networks (WSN) consists of independent sensors distributed across different locations, which are used to continuously record the environmental or physical conditions. The recorded data will be passed through the network from a sensor to a main location. Sensors life time is based on the battery power. Lower the battery power leads to decrease in lifetime for a sensor. It is important...
Wireless sensors are used to acquire the data from different environments such civilian applications, military, tracking, seismic measurements and monitoring applications in order to take necessary actions or to prevent the disasters, to do so all sensors consumes more energy. Since, the sensor is a battery operated device the lifetime of each sensor is reduced. Therefore effective cluster formation...
Battery durability is often the major constraint in low power wireless sensor networks. Hence in most low power scheduling methods, nodes switch between the active mode and sleep mode periodically.
