Unbalanced energy consumption in heterogeneous wireless sensor networks (HWSNs) results in the “energy-hole” problem. In this paper, a novel Energy-Balanced Unequal Clustering Protocol (EBUCP) is proposed to address the energy-hole problem. In EBUCP, three kinds of sensor nodes named normal nodes, advanced nodes and super nodes are deployed in a circular region which is divided into multilayer rings...
For single sink multi-hop wireless sensor networks, the nodes close to the sink node forward the total network traffic to the sink. Hence, they exhaust their energy faster and energy-holes are formed near the sink node that reduces the lifetime of the network. To enhance the network lifetime and to reduce the packet delay, multiple sink node deployment strategies are proposed for better load balancing,...
The application areas of wireless sensor network often suffered from the threat of limited energy resources. The potentiality of the applications is directly dependent on the number of active sensor nodes are available within the sensor network. Maximizing the lifetime of the sensor nodes is the ultimate way to improve the lifetime of the entire sensor network. Considering mobile sink node raises...
The demand for maximum network lifetime in many mission-critical applications of wireless sensor networks motivates the great significance to deploy as few sensors as possible to achieve the expected network performance. In this paper, we first characterize the energy consumption of wireless sensor networks with adjustable transmission ranges through theoretical analysis. Based on this result, we...
