This paper contributes to recent improvements in energy-efficient clustering algorithms for static and homogeneous wireless sensor networks. We propose a modified algorithm, called NREC, which considers information on the locally normalized residual energy of sensor nodes. This information is weighted with the probabilistic threshold used in standard algorithms for periodic election of cluster heads...
Collecting data from a large wireless sensor network (WSN) is a challenging issue and there are mainly two approaches to increase the efficiency: by hierarchical routing based on node clustering and by mobile elements (MEs). Since either method has pros and cons, this paper presents a hybrid approach, called Node Density based Clustering and Multiple Mobile Collection (NDCMMC), to combine the hierarchical...
A wireless sensor network (WSN) is a collection of spatially distributed autonomous sensor nodes that can be used to monitor, among other things, environmental conditions. WSN sensor nodes are constrained by their limited energy supply, communication range and local computational capabilities. Data routing is an area that can be optimized to allow nodes to conserve energy, improving the network's...
To perform some operation there is a need of some amount of energy over the node is same to the sending the single bit of data in the network. Data transportation reduces the network lifetime when sending data in sensor network. So the need to reduce the energy consumption for improving the network lifetime. As cluster head is aggregator node of the cluster it can take part in communication many times...
