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 …

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 …

In this paper we investigate the benefits of a heterogeneous architecture for wireless sensor
networks composed of a few resource rich mobile nodes and a large number of simple static …

We address the problem of maximizing the lifetime in a wireless sensor network with energy-
constrained sensor nodes and mobile data collection points (sinks). Information generated …

Data collection architectures for static sensor networks typically adopt a multipoint-to-point
routing model in which data from individual sensors is routed to strategically placed static …

Sažetak In this paper we address the problem of maximizing the lifetime in a wireless sensor
network with energy and power constrained sensor nodes and mobile data collection point …

Optimizing energy consumption in wireless sensor networks is of paramount importance.
There is a recent trend to deal with this problem by introducing mobile elements (sensors or …

Sink mobility has attracted much research interest in recent years because it can improve
network performance such as energy efficiency and throughput. An energy-unconscious …

In multihop wireless sensor networks that are often characterized by many-to-one
(convergecast) traffic patterns, problems related to energy imbalance among sensors often …

A major challenge affecting the lifetime of Wireless Sensor Networks (WSNs) comes from the
unbalanced energy consumption over different parts of the network. This unbalanced energy …
