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...

Optimally Mapping an Iterative Channel Decoding Algorithm to a Wireless Sensor Network
–Retransmission based schemes are not suitable for energy constrained wireless sensor networks. Hence, there is an interest in including parity bits in each packet for error cont...
