Energy hole problem is a crucial issue in wireless sensor network (WSN). Nodes near the
sink region will die sooner from outer sub-regions because these nodes send their own data …

In wireless sensor network (WSN), there is a problem of energy hole, which means nodes
near the sink region will die sooner because these nodes send their own data to sink as well …

This paper theoretically proposes a more accurate analytical method for avoiding energy
hole in wireless sensor networks with nonuniform node distribution. Based on the typical …

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 …

In single-sink wireless sensor networks, the data traffic follows a many-to-one pattern. This
makes nodes around the sink exhaust their energy prematurely and leads to an energy hole …

In this paper, we investigate the theoretical aspects of the nonuniform node distribution
strategy in wireless sensor networks, which aims to avoid the energy hole around the sink …

The energy hole phenomenon has been a great hinderance in efficient performance of
Wireless Sensor Networks (WSNs). In this paper, energy hole problem is addressed with …

Prolonging the network lifetime is one of design challenges for data transmission in wireless
sensor networks (WSNs) which are affected by the energy sink-hole problem. Recent …

Wireless sensor networks are characterized by multihop network. Some nodes in network
are required to forward a disproportionately high amount of traffic and die early, leaving the …

In Wireless Sensor Networks (WSN), the lifetime of a uniformly deployed WSN is impaired by
the sensors that are close to the sink, by a phenomenon called energy hole problem. Those …
