Abstract
Two economic factors are essential for the success of wireless sensor networks as new key technology: low-cost hardware and strong prototype applications. Although not perfect, Bluetooth can be a driving technology in this domain. We present a new 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 hardware. DCP is scalable, robust, and not limited to piconet or scatternet structures.
