—Code dissemination in wireless sensor networks refers to the process of disseminating a new code image via wireless links to all sensor nodes after they are deployed. It is desi...
It is well known that optimal server placement is NP-hard. We present an approximate model for the case when both clients and servers are dense, and propose a simple server alloca...
In this paper we consider a distributed and efficient information dissemination and retrieval system for wireless sensor networks. In such a system each sensor node operates auton...
Wireless sensor networks (WSNs) deployed for missioncritical applications face the fundamental challenge of meeting stringent spatiotemporal performance requirements using nodes w...

— We propose a distributed algorithm to detect “cuts” in sensor networks, i.e., the failure of a set of nodes that separates the networks into two or more components. The alg...
