We investigate the benefits of a heterogeneous architecture for wireless sensor networks
(WSNs) composed of a few resource rich mobile relay nodes and a large number of simple …

Sensors are used to monitor and control the physical environment. In mobile sensor
networks, nodes can self-propel via springs, wheels, or they can be attached to transporters …

The longevity of wireless sensor networks (WSNs) is a major issue that impacts the
application of such networks. While communication protocols are striving to save energy by …

Although many energy efficient/conserving routing protocols have been proposed for
wireless sensor networks, the concentration of data traffic towards a small number of base …

A critical issue for data gathering in wireless sensor networks is the formation of energy
holes near the sinks. Sensors near the sinks have to participate in relaying data on behalf of …

Unlike traditional multihop forwarding among homogeneous static sensor nodes, use of
mobile devices for data collection in wireless sensor networks has recently been gathering …

A critical issue for data gathering in wireless sensor networks is the formation of energy
holes near the sinks. Sensors near the sinks have to participate in relaying data on behalf of …

Improving network lifetime is a fundamental challenge of wireless sensor networks. One
possible solution consists in making use of mobile sinks. Whereas theoretical analysis …

We consider a mobile ad hoc sensor network. The mobility of the sensor nodes is designed
with the cost of communication and mobility in mind along with consideration of the possible …
