Area-partitioned clustering and cluster head rotation for wireless sensor networks

2017 International Conference on Machine Learning and Cybernetics (ICMLC), 2017
A wireless sensor network (WSN) is composed of power-limited devices with constraints of size and condition etc. Due to impossibility to recharge or to replace the batteries of sensors, power control becomes a challenging issue in a WSN. To prolong the network lifetime, clustering is one of viable approaches.

Cluster Head Selection Using Modified ACO

2014
WSNs have limited computation power, battery life, and memory resources. In this paper, an approach is introduced to selection cluster head by using swarm intelligence. This proposed approach is based on LEACH clustering algorithm. Modified version of ant colony optimization by using residual energy as a parameter is employed over LEACH algorithm for ...

Hybrid model for security-aware cluster head selection in wireless sensor networks

IET Wireless Sensor Systems, 2019
Wireless sensor network (WSN) is considered as the resource constraint network, in which the entire nodes have limited resources. In WSN, prolonging the lifetime of the network remains as the unsolved point.

Block Division for 3D Head Shape Clustering

2009
In our previous Three Dimensional (3D) anthropometric shape clustering study, block-division technique is adopted. The objective of this study was to examine the sensitivity of clustering results on block-division. Such a block-division technique means to divide each 3D surface into a predefined number of blocks. Then by using a block-distance measure,

Cluster Algorithm for Electing Cluster Heads Based on Threshold Energy

2010 International Conference on Electrical and Control Engineering, 2010
One of important requirements for many Wireless sensor network applications is to prolong network lifetime. The cluster head consumes more energy than other member nodes, because it gathers data from its member nodes, processes it (e.g. data fusion), and transfers data to the sink node or to the base station that maybe located remotely.

optimization of Cluster Head Selection in Hierarchical Clustered Sensor Networks

2018 7th International Conference on Reliability, Infocom Technologies and Optimization (Trends and Future Directions) (ICRITO), 2018
Wireless Sensor Networks as a field in wireless communication is thriving and it comprises of a collection of spatially distributed autonomous sensors that are employed for monitoring the physical and environmental changes. But, these sensor nodes have energy limitations and to overcome this limitation, there is a need for energy efficient techniques ...

An improved energy efficient cluster head selection protocol using the double cluster heads and data fusion methods for IoT applications

Cognitive Systems Research, 2019
The more energy consumption is the major issue for wireless sensor network. In wireless sensor network (WSN), sensor nodes are fixed in various routing algorithms. In the same networks, mobile sensor and fixed sensor nodes are combine and its used in few

Adaptive cluster heads selection for fan-shaped clusters in WSNs

2018 IEEE Workshop on Environmental, Energy, and Structural Monitoring Systems (EESMS), 2018
Cluster-based routing schemes have attracted a great deal of interests due to the high data forwarding efficiency in large scale sensor networks. In this paper, we propose a fan shaped cluster scheme with an adaptive cluster heads (CHs) selection mechanism for large scale wireless sensor networks (WSNs).
