An effective approach for energy conservation in wireless sensor networks is scheduling sleep intervals for extraneous nodes, while the remaining nodes stay active to provide cont...
Exploiting directional antenna technology in wireless networks has become an attractive option because of the potential capacity increase through spatial reuse. Such development a...
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 ...
Abstract—We study the ubiquitous data collection for mobile users in wireless sensor networks. People with handheld devices can easily interact with the network and collect data....
—The majority of the existing ad hoc wireless network routing protocols has a tendency to use the shortest single path from the source to the destination. However, in constantly ...
