Energy conservation is one of the most important design considerations for battery powered
wireless sensors networks (WSNET). Energy constraint in WSNETs limits the total amount of …

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

Network lifetime is a crucial performance metric to evaluate data-gathering wireless sensor
networks (WSNs) where battery-powered sensor nodes periodically sense the environment …

Static always-on wireless sensor networks (WSNs) are affected by the energy sink-hole
problem, where sensors nearer a central gathering node, called the sink, suffer from …

As many sensor network applications require deployment in remote and hard-to-reach
areas, it is critical to ensure that such networks are capable of operating unattended for long …

In this paper, we investigate the theoretical aspects of the nonuniform node distribution
strategy used to mitigate the energy hole problem in wireless sensor networks (WSNs). We …

In this paper we investigate the problem of uneven energy consumption in a large class of
many-to-one sensor networks. In a many-to-one sensor network, all sensor nodes generate …

Over the last decade a large number of routing protocols has been designed for achieving
energy efficiency in data collecting wireless sensor networks. The drawbacks of using a …

In this paper, we investigate the use of limited infrastructure, in the form of wires, for
improving the energy efficiency of a wireless sensor network. We call such a sensor network …
