Exploiting multi-channel clustering for power efficiency in sensor networks

Sensor networks typically comprise of a number of inexpensive small devices with processing, communication and sensing abilities that collaborate to perform a common task. Sensor devices use batteries as their sole power supply. The operational lifetime of a sensor network, therefore, depends entirely on the better utilization of the devices. Typically a sensor network is divided into clusters to optimize power utilization by performing division of labor and data aggregation within a cluster. This paper introduces a novel approach to naturally distributed clustering of sensor nodes in a sensor net using multi channel data planes. Our technique incorporates a virtual sense mechanism that reduces energy spent in sampling and transmission. It also decreases network traffic, thereby decreasing contention, potential collisions and retransmissions. This approach inherently implements a sleep-awake mechanism based on virtual sensing that contributes towards increasing the network lifetime by ...
