On Distributed Time-Dependent Shortest Paths over Duty-Cycled Wireless Sensor Networks
Abstract—We revisit the shortest path problem in asynchronous duty-cycled wireless sensor networks, which exhibit time-dependent features. We model the time-varying link cost and...

On Multihop Broadcast over Adaptively Duty-Cycled Wireless Sensor Networks
Abstract. We consider the problem of multihop broadcast over adaptively duty-cycled wireless sensor networks (WSNs) where neighborhood nodes are not simultaneously awake. We presen...

Completely Distributed Low Duty Cycle Communication for Long-Living Sensor Networks
A lifetime of several years for wireless sensor nodes can be achieved if their activity period is minimized. This can be done by using low duty cycle protocols. One of the challeng...

Approximation Algorithms for Power-Aware Scheduling of Wireless Sensor Networks with Rate and Duty-Cycle Constraints
We develop algorithms for finding the minimum energy transmission schedule for duty-cycle and rate constrained wireless sensor nodes transmitting over an interference channel. Sinc...
