We propose a power efficient system architecture that exploits the characteristics of sensor
networks in order to decrease the power consumption in the network. The primary …

Attempts to develop a ubiquitous health care monitoring system arisen from the need of
automatic real-time medical services for emergent diseases. Besides, the physiological …

This paper proposes a simple protocol for low-power sensor networks with battery-operated
sensing devices. The sensors are expected to become active only when certain events in …

In this paper, we investigate an energy-efficient data gathering scheme that prolongs the
lifetime of battery-powered sensor nodes. We consider two points in our scheme: turning off …

We propose a novel, cluster-based, energy-efficient scheme in this paper. A modified
LEACH algorithm is used to dynamically cluster the networks. It balances the energy …

A sensor network is a collection of wireless sensor nodes, each equipped with embedded
processor, memory, and a wireless transceiver, that may be designed to perform distributed …

Recent years have seen a burgeoning interest in embedded wireless sensor networks with
applications ranging from habitat monitoring to medical applications. Wireless sensor …

In a wireless sensor-actuator network (WSAN), sensors send sensed values to actuators in a
wireless channel. Messages sent by nodes might be lost due to collision and noise if …

It is challenging to design a sensor network if sensors are battery powered. Efficient
scheduling and budgeting battery power in sensor networks has become a critical issue in …

Due to the fact that sensor nodes are untethered and unattended, energy management is a
critical issue in communication mechanism of a wireless sensor network. In this paper, we …
