Wireless sensor networks are energy constraint networks. Energy efficiency, to prolong the network for a longer time is critical issue for wireless sensor network protocols. Clustering protocols are energy efficient approaches to extend the lifetime of network. Intra-cluster communication is the main driving factor for energy efficiency of clustering protocols. Intra-cluster energy consumption ...

Clustering is an effective approach for managing nodes in Wireless Sensor Network (WSN). A new method of clustering mechanism with using Binary Gravitational Search Algorithm (BGSA) in WSN, is proposed in this paper to improve the energy consumption of the sensor nodes. Reducing the energy consumption of sensors in WSNs is the objective of this paper that is through selecting the sub optimum se...

In recent years there has been a growing interest in Wireless Sensor Networks (WSN). Recent advancements in the field of sensing, computing and communications have attracted research efforts and huge investments from various quarters in the field of WSN. Also sensing networks will reveal previously unobserved phenomena. Network’s lifetime depends on energy efficiency and load balancing of wirel...

Technological developments on wireless communication systems and sensors productivity-enhancing wireless sensor networks have led the development of new algorithms. Wireless sensor devices (nodes) were developed along with the use of these two cases, and data collected has been achieved forwarded to a central location. Studies in the literature were shown that, WSN (wireless sensor networks) sy...

Enhancing lifetime of sensor nodes should be considered as the key design objective in Wireless Sensor Networks (WSN). A sensor node can only be equipped with a limited energy supply and it loses its energy during data communication. In some application scenarios, replenishment of energy resources might be impossible since the sensor nodes are distributed in remote environment. Hence, the nodes...

In this paper, we present a unique approach that provides cluster level data-reliability with low energy consumption. Prior to presenting the algorithm, we present a cluster-head selection algorithm which would ensure prolonged lifetime of the cluster as well as the health of the chosen cluster-head during its elected period. Our scheme not only ensures reliability of data aggregated at the clu...

Hierarchical Clustering is a procedure of cluster analysis which aims to construct a hierarchy of clusters. There are two kinds of hierarchical clustering i.e. Agglomerative, which is a bottom – up approach, where all the observations start in its own cluster, and pairs of clusters are merged moving up the hierarchy, and the other one is divisive, which is a top down approach, where each observ...

In wireless sensor networks (WSN), the current cluster based routing techniques may result in increased network workload, energy consumption and re-transmissions. In order to overcome these issues, in this paper, we propose an energy efficient double cluster head selection algorithm for wireless sensor network. In this technique, two cluster heads namely main and sub-ordinate cluster heads are ...
