In-network data aggregation is often pursued to remove redundancy and correlate the data en-route to the base-station in order to save energy in wireless sensor networks (WSNs). In this paper, we present a novel cross-layer ...

Wearable computing is becoming a more and more attracting field in the last years thanks to the miniaturisation of electronic devices. Wearable healthcare monitoring systems (WHMS) as an important client of wearable computing ...

This paper deals with power-efficient coverage in wireless sensor networks (WSN) by taking advantage of energyharvesting capabilities. A general scenario is considered for deployed networks with two types of sensor nodes, ...

Microsecond-level time synchronization is needed in realtime applications of wireless sensor networks. While several synchronization protocols have been proposed, most performance evaluations have been limited to ...

This paper considers a variant of the connected dominating set (CDS) problem in a graph G = (V;E). The considered problem consists in minimizing the number of CDS vertices that belong to a subset V ′ in V . As far as ...

This paper studies the problem of data aggregation scheduling in wireless sensor networks (WSNs) to minimize time latency. In prior work on this problem, a node is assigned a parent from the set of unscheduled nodes in ...
