Many consumer products in the home environment are managed by the Wireless Sensor
Networks (WSNs). However, the energy hole problem in the WSNs which with logical ring
topology and uniformly distributed sensors is usually caused by the energy exhaustion of the
sensors which distributed in the first radius range of the sink. This paper firstly analyzed the
energy consumption model of the sensor, the data transmission model of the sensor, and the
energy consumption distribution model of the WSNs. Then, a WSN Energy Hole Alleviating …

Illegal nodes can send malicious data to WSN continuously, which will accelerate the
energy consumption rate. Even if the cluster heads in the inner regions have been
exhausted simultaneously, the ones in the outer regions may still hold sufficient energy
resource. This situation is defined as energy-hole problem in WSN. To investigate the
principle of such problem and design corresponding defense strategies, it is critical to
analyze the configuration and distribution of cluster heads. According to the balance …
