Because of limited energy of nodes, an important issue for sensor network is efficient use of the energy. The clustering technique reduces energy consumption as cluster head sends sensed information to a sink node. Because of such character of clustering technique, electing cluster head is an important element for networks. This paper proposes RCFT(Re-Clustering Formation Technique) that recons...

The wireless sensor networks combines sensing, computation, and communication into a single small device. These devices depend on battery power and may be placed in hostile environments replacing them becomes a tedious task. Thus improving the energy of these networks becomes important. Clustering in wireless sensor network looks several challenges such as selection of an optimal group of senso...

Secure data transmission and data aggregation are critical in designing cluster-based sensor networks. This paper presents an Energy-efficient and Secure Pattern-based Data Aggregation protocol (ESPDA) for wireless sensor networks. ESPDA is energy and bandwidth efficient because cluster-heads prevent the transmission of redundant data from sensor nodes. ESPDA is also secure because it does not ...

Clustering in Mobile Ad-hoc Networks (MANETs) has become a crucial research issue in modern days, because clustering can improve system performance of MANETs. As MANETs have limited battery power supply, cluster formation is costly in terms of power depletion of nodes in the cluster. This is due to the huge amount of messages transmission required during cluster formation and further data trans...

The work proposed a three-layer framework is proposed for mobile data collection in wireless sensor networks, which contains sensor layer, cluster head layer, and mobile collector (called SenCar) layer. The framework employ distributed load balanced clustering and dual data uploading, which is referred to as LBC-DDU. The objective is to achieve good scalability, and low data collection latency....

The wired mode of communication will no longer serve the purpose of our present scenario network where the expectations in communications system have been skyrocketed. Thus, wireless network with ad hoc nature will suit the present and forthcoming real world applications. This ad hoc wireless network will bind the entire globe and will reign the communication system tomorrow. But, ad hoc networ...

Underwater Wireless Sensor Network (UWSN) is a particular kind of sensor networks which is characterized by using acoustic channels for communication. UWSN is challenged by great issues specially the energy supply of sensor node which can be wasted rapidly by several factors. The most proposed routing protocols for terrestrial sensor networks are not adequate for UWSN, thus new design of routin...

This paper presents a grid-based distributed event detection scheme for wireless sensor networks. The network is divided into square-shaped grids of predefined grid size, where sensor nodes in each grid form a cluster with a cluster head. Event detection at each grid alone based on the readings of its member nodes is limited in event detection performance, especially for a small event region co...

Aiming at the issue of moving multi-target tracking (MMTT) in double wireless video sensor network, this paper proposes a dynamic node cooperative program and a tracking forecasting association program. Particle multi-Bernoulli filtering algorithm is applied to perform the sensor cooperative scheme proposed, including cluster head node selecting scheme and cluster members selecting scheme. At e...

Several MANET characteristics that distinguish MANET from other wireless networks and makes routing a challenging task. This paper presents a novel clustering algorithm, which uses both internal and external factors of node in mobile ad hoc network. In Cluster based MANET routing scheme, various mobile nodes are formed as clusters. Each cluster has its own cluster head, which is having more res...
