Abstract-- Wireless sensor networks (WSNs) require energyef cient protocols to improve the network lifetime. In this work, we adopt a cross-layer strategy that considers routing an...
A critical issue in the design of routing protocols for wireless sensor networks is the efficient utilization of resources such as scarce bandwidth and limited energy supply. Many ...
We study the multicast problem in wireless sensor networks, where the source can send data to a fixed number of destinations (actuators) at a different rate (multiratecast). A typi...
Geographic routing is of interest for sensor networks because a point-to-point primitive is an important building block for data-centric applications. While there is a significant...

Besides energy constraint, wireless sensor networks should also be able to provide bounded communication delay when they are used to support real-time applications. In this paper,...
