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(More)
Energy efficiency is main design issue for protocols of wireless sensor networks. Node clustering is an energy efficient approach for sensor networks. In clustering algorithms, nodes are grouped into independent clusters and each cluster has a cluster head. Data units gathered at base station depends upon lifetime of network. Cluster head selection is an(More)
Clustering algorithms are considered as energy-efficient approach for resource-constraint wireless sensor networks. Traditional clustering algorithms have uneven clusters that make network load unbalanced. In this paper, a clustering approach is proposed to address this problem and it provides balanced clusters by considering thresholds for cluster(More)
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 is an efficient approach to capitalize the energy of sensor nodes in wireless sensor networks. LEACH is a fully distributed clustering scheme that chooses cluster head(More)
As wireless sensor networks are energy constraint networks so energy efficiency of sensor nodes is the main design issue. Clustering of nodes is an energy efficient approach. It prolongs the lifetime of wireless sensor networks by avoiding long distance communication. Clustering algorithms operate in rounds. Performance of clustering algorithm depends upon(More)
Clustering is an efficient approach to capitalize the energy of energy constraint sensor nodes in wireless sensor networks. Clustering schemes do not guarantee formation of clusters with equal number of nodes. So data frames transmitted by the nodes vary. TDMA schedule of nodes of smaller cluster is smaller than others that results more number of data(More)
In recent time, wireless sensor networks are gaining popularity among research persons. Wireless sensor networks are energy constraint networks because sensor nodes carry limited energy. Energy efficiency is the prime design issue for wireless sensor networks. Clustering algorithms increase performance of network with reduction in energy consumption of(More)
