Energy-efficient data collection for Bluetooth-based sensor networks

A wide range of sensor network applications deals with an issue often referred to as data collection: sensor nodes periodically transmit data to a base station. The base station analyzes incoming data for interesting events. In this paper, we introduce a novel data collection protocol (DCP) for wireless sensor networks. DCP is tailored to Bluetooth-based sensor nodes and therefore enables sensor network applications based on inexpensive COTS-hardware. DCP is scalable, robust and not limited to piconet or scatternet structures. As a potential application of DCP, we describe a wireless sensor network deployed as flood prevention system.
