Energy consumption represents a key element in the Wireless Sensor Networks (WSNs) design. Several factors can cause energy over consumption such as mobility, node position (relay or gateway), retransmissions... The network topology can also be a major cause of energy waste: a transmission in 1-hop requires a high energy, a transmission in K-hops requires a lower energy, even though, it can damage...

Wireless Sensor Network (WSN) is a network of portable and lightweight sensors used to monitor a specific field and report the data they detect wirelessly to a sink node responsible for the analysis and decision making. WSNs have limited power as well as resources. More advanced sensors known as "multimodal sensors" can report more than one feature, which requires even more efficient utilization...
Clustering is believed to be the solution to the needs of energy efficiency as well as scalability in Wireless Sensor Network (WSN) application. In traditional clustering, each node belongs to only one cluster. However, some applications need some nodes to affiliate to more than one cluster. We propose a clustering algorithm that has capability to control the overlapping between clusters with still...
In WSN, sensors near the sink have to relay the data of the nodes away from the sink and as a result they drain their energy very quickly. It result in network partitioning and can significantly limit the network lifetime. This problem is termed as hotspot problem. Recently, formation of hot spot or energy hole near the sink has emerged as a critical issue for data gathering in WSN. In this paper,...
