Connection Oriented Sensor Networks

This dissertation is about sensor networks, and connection oriented communication. We present an overview of the field of sensor networks, and advocate the use of connection oriented communication technologies, such as spread spectrum radios. We claim that low duty sensor networks should use frequency synchronized radios. We additionally claim that low duty operation on a single channel is actually connection based, and requires a discovery phase. We claim that the area of discovery is underdeveloped and needs attention. We present a novel approach to discovery on a shared network channel: Increased Beacon Frequency Discovery. Finally, we claim that the need to support nodes in joining a sensor network, cost substantial energy. We support our claims through analysis, and a prototype of a Bluetooth based sensor network.
