Managing scarce resources in wireless sensor networks
The efficient management of scarce network resources such as energy and bandwidth is a key challenge in wireless sensor networks, and is typically addressed through the introduction of control mechanisms at the MAC and network layers. However these control mechanisms incur communication and processing overhead that does not scale well for large or dense networks. Instead, we propose a simple combination of directed broadcast and neighbour message overhearing which is more suitable for such networks. This work is published in the December 2009 issue of the journal ACM Transactions on Sensor Networks.
