A mobile ad hoc network (MANET) is dynamic in nature and is composed of wirelessly connected nodes that perform hop-by-hop routing without the help of any fixed infrastructure. One of the important requirements of aMANET is the efficiency of energy, which increases the lifetime of the network. Several techniques have been proposed by researchers to achieve this goal and one of them is clusterin...

In this paper, we propose Regional Energy Efficient Cluster Heads based on Maximum Energy (REECH-ME) Routing Protocol for Wireless Sensor Networks (WSNs). The main purpose of this protocol is to improve the network lifetime and particularly the stability period of the network. In REECH-ME, the node with the maximum energy in a region becomes Cluster Head (CH) of that region for that particular ...

Wireless sensor network (WSN) consists of a large number nodes distributed over certain target area. The WSN plays vital role in surveillance, advanced healthcare, and commercialized industrial automation. Enhancing energy-efficiency the is prime concern because higher energy consumption restricts lifetime (LT) network. Clustering powerful technique widely adopted to increase LT reduce transmis...

The network lifetime of the Wireless Sensor Networks (WSNs) is a critical factor for relevant applications due to limited energy supply.

A Wireless Sensor Network (WSN) contains a large number of sensor nodes equipped with limited energy supplies. In most applications, sensor nodes are deployed in a random fashion. Therefore, battery replacement or charging is considered not practical. As a result, routing protocols must be energy-efficient to prolong the network’s lifetime.

Clustering is one of the popular topology management approaches that can positively influence the performance of networks. It plays significant role in VANETs. However, VANETs having highly mobile nodes lead to dynamic topology and hence, it is very difficult to construct stable clusters. More homogeneous environment produces more stable clusters. Homogeneous neighborhood for a vehicle is stron...

Wireless distributed sensor network consists of randomly deployed wireless sensors having low energy assets. These networks can be used for monitoring in a variety of environments.

We propose Distributed Regional Energy Eff...

Wireless sensor networks (WSNs) can facilitate continuous monitoring of patients and increase early detection of emergency conditions and diseases. High density WSNs helps us to accurately monitor a remote environment by intelligently combining the data from the individual nodes.

Using a mobile sink is a type of promising application in wireless sensor networks (WSNs). To minimize the number of static nodes that are awake while the mobile sink is gathering data, it is beneficial to use cluster heads (CHs) for network management and operation, thereby saving energy in communication. During the network design, deciding an appropriate number of CHs is an important thing to...

Technological advancements have led to increased confidence in the design of large-scale wireless networks that comprise small energy constraint devices.
