Clustering schemes offer a practical way of providing scalability when dealing with large and dense Mobile Ad hoc Networks (MANETs). The feasibility of a clustering method can be primarily determined by the complexity of the cluster head selection. Optimizing the cluster head selection allows for the network to be more efficient by minimizing the signaling overhead while ensuring that the netwo...

This article focused on the energy limit property of Wireless Sensor Network, and proposed a residual energy based algorithm WRECS, which is improved on classical routing algorithm LEACH. The algorithm took the normalized residual energy and the cumulative number of the normal nodes supported by the cluster heads as clusterheads selection parameters. In order to balance the energy consumption o...

Wireless sensor networks require energy-efficient data transmission because the sensor nodes have limited power. A cluster-based routing method is more energy-efficient than a flat routing method as it can only send specific data for user requirements and aggregate similar data by dividing a network into a local cluster. However, previous clustering algorithms have some problems in that the tra...

We propose an energy-efficient hierarchical cluster-based routing (HCR) protocol where nodes self-organize into clusters and each cluster is managed by a set of associates called head-set. Using round-robin technique, each head-set member acts a cluster head (CH). The sensor nodes transmit data to their cluster heads, which transmit the aggregated data to the base station. Moreover, the energy-...

Power conservation is important in sensor devices since battery life is usually one of the critical components in extending the life time of the sensor network. Cluster technology that enables a group of sensors working closely to form a single cluster head, has been a booming research field in sensor network. When cluster heads cooperate with each other to forward their data to the base statio...

Wireless Sensor Networks are often battery-powered, and hence extending the networking lifetime is one of the primary concerns in the ubiquitous deployment of wireless sensor networks. This paper introduces energy efficient MAC protocol used for wireless sensor networks. Energy consumption is the main problem in wireless sensor network. So minimize the energy consumption and make the life of se...

Clustering in Mobile Ad Hoc Networks (MANETs) has much better utilization compared to the conventional system. Other than the highly active and unbalanced nature of MANETs makes it hard for the cluster based routing protocols to split a mobile network into clusters and determination of cluster heads for each cluster. In this paper, we analyze and compare some of existing works on cluster based ...

Study on energy-efficient routing algorithms is one of the critical problems of wireless sensor networks. In this paper, we propose a Density-based Energy-efficient Game-theoretic Routing Algorithm (DEGRA). As a clustering algorithm, DEGRA adopts game theory and make cluster head determination based on nodes’ density, residual energy and average energy consumption of its neighboring nodes. We a...

The efficient use of energy source in a sensor node is most desirable criteria for prolong the life time of wireless sensor network. In this paper, we propose a two layer hierarchical routing protocol called Cluster Based Hierarchical Routing Protocol (CBHRP). We introduce a new concept called head-set, consists of one active cluster head and some other associate cluster heads within a cluster....

In order to prolong the network lifetime, energy-efficient protocols should be designed to adapt the characteristic of wireless sensor networks.
