Optimal stochastic routing in low duty-cycled wireless sensor networks
We study a routing problem in wireless sensor networks where sensors are duty-cycled. When sensors alternate between on and off modes, delay encountered in packet delivery due to ...

DHV: A Code Consistency Maintenance Protocol for Multi-hop Wireless Sensor Networks
Ensuring that every sensor node has the same code version is challenging in dynamic, unreliable multi-hop sensor networks. When nodes have different code versions, the network may...
