Smart Messages (SMs) are dynamic collections of code and data that migrate to nodes of interest in the network and execute on these nodes. A key challenge in programming pervasive...
Abstract—In contrast to existing work on the connected coverage problem in wireless sensor networks which assumes omnidirectional sensors with disk-like sensing range, this paper...

Unlike traditional multihop forwarding among homogeneous static sensor nodes, use of mobile devices for data collection in wireless sensor networks has recently been gathering more...
Abstract: We present PERT, a power-efficient scheme to deliver real-time data packets in sensor networks. Time-sensitive sensor data is common in applications such as hazard monito...
