Executive Summary

Micro Electro-Mechanical Systems (MEMS) have made in-situ sensing with Wireless Sensor Networks (WSNs) a promising technique. As wireless integrated network sensors are powered with a small battery and they usually work in an unattended manner, the main constraint of a sensor node is that its energy resource is limited. To enable in-situ sensing, sensor nodes and WSNs should function in an energy-efficient manner. Energy optimization techniques must be performed in every level of the design of a sensor network system. The work described various aspects of power saving approaches to achieve energy-efficient and reliable WSNs. PORT, a Price-Oriented Reliable Transport protocol for wireless sensor networks to reliably and energy-efficiently convey sensor information to the sink.
