Mobile Element Scheduling for Efficient Data Collection in Wireless Sensor Networks: A Survey

Free registration required

Executive Summary

A typical Wireless Sensor Network (WSN) consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion, at different locations. The development of WSNs was motivated by military applications. However, WSNs are now used in civilian applications, including environment, traffic and habitat monitoring, healthcare and home automation. The main challenges in the sensor networks are limited battery power and buffer overflow. An analysis of performance of the various existing methods for data collection in sensor networks has been performed.
