A new centralized clustering protocol for periodic traffic wireless sensor networks is proposed in this paper. The proposed protocol uses one-step off-line cluster computation algorithm, where all the clustering schemes and their respective durations are calculated by the base station (BS) once at the network initialization. This provides the BS a global vision and enables it to reach better clustering...
Topology control in wireless sensor networks (WSNs) balances the communication load on sensor devices and increases the network lifetime and scalability. Hierarchical or cluster-based design is one of the approaches to conserve the energy of the sensor networks in which the nodes with the higher residual energy could be used to gather data and route the information. However, most of the previous work...

To select fair and balanced cluster head for cross layer protocol in wireless sensor network, a novel scheme is proposed in this paper. Because LEACH-C and its most of the variants select cluster head by considering energy and distance as a crucial parameter, it can reduce energy consumption of nodes but fail to create balanced cluster. According to the requirement of fair CH selection, we consider...
Applicability of Wireless Sensor Networks is found in fields manifold. Energy issues proved to be a continuous setback to the performance of these networks. Data aggregation and the use of local base stations is seen as a promising solution to the problem. Clustering is a simple technique to achieve this. The local base stations or the cluster heads aggregate data from nearby nodes, process it and...
Clustering is an important technique that helps in reducing the network energy consumption. The Cluster Head (CH) usually performs data fusion, aggregation and communication of the aggregated data to the Base Station. As the CHs communicate with the Base Stations located at larger distances than the member nodes, they generally consume more energy. This leads to energy drainage of CHs at a faster...
The need for energy-efficient routing and data gathering protocols in large-scale environments becomes very challenging. Hierarchical routing in WSNs is a very important topic.
