In Wireless Sensor Networks (WSN), the clustering protocol requires the nodes local information like energy level, distance between to BS and node density, link quality and load while estimating the cluster heads to handle network lifetime. In this study, we propose fuzzy based optimal clustering protocol for maximizing lifetime in WSN. Initially, several provisional cluster heads are elected i...

Wireless Sensor Networks (WSN) have gained wide popularity and have increased tremendously in recent time due to growth in Micro-Electro-Mechanical Systems (MEMS) technology. WSN has the potentiality to connect the physical world with the virtual world by forming a network of sensor nodes. Energy saving of sensor nodes is a major design issue since sensor nodes are usually battery-operated devi...

In VANETs, a clustering algorithm can be used to partition the network into smaller segments.Therefore, the clustering algorithms provide not only limited channel contention but also fair channel access within the cluster. In addition, they also increase spatial reuse in VANETs and efficient control for the network topology.Themain concern in the clustering algorithm is the cluster stability. T...

Objective: The main objective of this paper is to construct a distributed clustering algorithm based upon spatial data correlation among sensor nodes and perform data accuracy for each distributed cluster at their respective cluster head node. Design Procedure/Approach: We investigate that due to deployment of high density of sensor nodes in the sensor field, spatial data are highly correlated ...

One critical issue in wireless sensor networks is how to gather sensed information in an energy-efficient way since the energy is a scarce resource in a sensor node. Cluster-based architecture is an effective architecture for data-gathering in wireless sensor networks. However, in a mobile environment, the dynamic topology poses the challenge to design an energy-efficient data-gathering protoco...

In wireless sensor networks (WSNs) energy is the main thing of sensor network, Energy is the irreplaceable part of the sensor node, To reduce the energy consumption researchers gives a lot of ideas to increase the life period of the sensor node, Researchers used a cluster head and a gateway to reduce the work load of the sensor network , but we know all the sensor node, gateway and cluster head...

Because of the energy load imbalance of cluster nodes in wireless sensor networks, this causes cluster heads tend to die earlier in the case of more tasks and routing problem such as larger energy loss, so an adaptive energy optimization clustering routing algorithm is proposed. The node residual energy and distance are taken into full consideration by the measure coefficient on the cluster-hea...
