In a wireless sensor network where sensors are arranged into a flat topology, sensors near
the sink consume much more energy than sensors at the boundary of the network. Sensors …

In this paper, the energy hole problem in wireless sensor networks is modeled, and a novel
transmission range adjustment method is proposed to solve the problem. The goal of our …

The Energy hole problem, a common phenomenon in wireless sensor networks, significantly
decreases the lifetime of any deployed network. Some of the popular techniques to minimize …

The many-to-one communication nature of wireless sensor networks (WSNs) leads to an
unbalanced traffic distribution, and, accordingly, sensor nodes closer to the base station …

In wireless sensor networks, energy balancing and energy efficiency are the key
requirements to prolong the network lifetime. In this paper, we investigate the problem of …
