Optimal Cluster Head Rotation for Heterogeneous WSNs

2020
Heterogeneous Wireless Sensor Networks (WSNs) are an essential part of the Internet of Things (IoT). WSNs are composed of battery powered devices with limited processing capabilities in terms of CPU, memory and transmission range. As opposed to homogeneous WSNs where nodes are all equal, heterogeneous ones are composed of nodes that can have different ...

Optimal Cluster Head Selection in the LEACH Architecture

2007 IEEE International Performance, Computing, and Communications Conference, 2007
LEACH (low energy adaptive clustering hierarchy) (W. Heinzelman et al., 2000) is one of the popular cluster-based structures, which has been widely proposed in wireless sensor networks. LEACH uses a TDMA based MAC protocol, and in order to maintain a balanced energy consumption, suggests that each node probabilistically become a cluster head. To reduce

Genetic Algorithm-based Optimized Cluster Head selection for single and multiple data sinks in Heterogeneous Wireless Sensor Network

Applied Soft Computing, 2019
The constraints on the battery resources of sensor nodes have been the major stumbling block in achieving the network longevity and in exploring the potential of Wireless Sensor Network (WSN) to the maximum level.

Clustering and load balancing in hybrid sensor networks with mobile cluster heads

Proceedings of the 3rd international conference on Quality of service in heterogeneous wired/wireless networks - QShine '06, 2006
In this paper, we consider the problem of positioning mobile cluster heads and balancing traffic load in a hybrid sensor network, which consists of two types of nodes: basic static sensor nodes and mobile cluster heads. In such a network, sensor nodes are organized into clusters and form the lower layer of the network.

Content Aided Clustering and Cluster Head Selection Algorithms in Vehicular Networks

2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017
Relying on clustering and the cluster head selection algorithms, vehicle-to-vehicle (V2V) and vehicle-to- infrastructure (V2I) based vehicular ad hoc networks (VANETs) play a critical role in intelligent transport system (ITS). However, the existing clustering and cluster head selection algorithms did not consider the influence of the vehicles ...

RCH-LEACH: Residual Energy based Cluster Head Selection in LEACH for Wireless Sensor Networks

International Conference on Electrical and Electronics Engineering, 2020
Information sensing in an energy-efficient manner is the prime object of Wireless Sensor Networks (WSNs). WSN consist of randomly deployed sensor nodes, which are distributed into different clusters using different techniques of clustering.

Improvement on Cluster Based Routing Protocol by Using Vice Cluster Head

2010 Fourth International Conference on Next Generation Mobile Applications, Services and Technologies, 2010
The main objective of routing protocol is to transfer data more efficiently from the source to the destination. All routing protocols have the same in this goal, but the method that adopts to achieve this is different. This paper propose a new modification of CBRP protocol called Vice Cluster Head Cluster Based Routing Protocol (VCH-CBRP) that elect ...

An efficiency of broadcast mechanisms based on Cluster Heads in clusterized radio network

2015 International Conference on Military Communications and Information Systems (ICMCIS), 2015
Efficiency of broadcast transmission based on Cluster Heads in clusterized wireless network has been assessed in this paper. The proposed algorithm uses MPR (Multi Point Relay) method based on Cluster Heads (CH-MPR-BC). Most results were compared with classical solution which uses GateWay nodes at the edge of clusters as retransmitters.

DECH: Equally Distributed Cluster Heads Technique for Clustering Protocols in WSNs

Wireless Personal Communications, 2015
Recent research works focus on the development of wireless sensor networks, leading to the arrival of new protocols. One of the goals of a routing protocol is reducing the power consumption. Clustering techniques are used in routing protocols to increase network lifetime and reduce network overhead. Major clustering protocols like LEACH, TEEN, DEEC and

Low energy adaptive clustering hierarchy with deterministic cluster-head selection

4th International Workshop on Mobile and Wireless Communications Network, 2003
This paper focuses on reducing the power consumption of wireless microsensor networks. Therefore, a communication protocol named LEACH (low-energy adaptive clustering hierarchy) is modified. We extend LEACH's stochastic cluster-head selection algorithm by a deterministic component.
