Inter- and intra-cluster movement of mobile sink algorithms for cluster-based networks to enhance the network lifetime

Ad hoc networks, 2019
Due to limited resources of the sensor nodes energy efficiency is an important performance metric to evaluate the wireless sensor networks (WSN). In cluster-based WSNs, the cluster heads (CH) located around base station (BS) consume more energy and ...

Lifetime Extension Approach Based on the Levenberg–Marquardt Neural Network and Power Routing of DC–DC Converters

IEEE transactions on power electronics, 2023
The power conversion system based on the modular connection has widespread applications in various power electronic systems. To accurately estimate the state of health without recognizing the systematic mathematical model and to extend the lifetime, this

On enhancing network-lifetime in opportunistic Wireless Sensor Networks

2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014
Network lifetime has become the key characteristic for evaluating sensor networks in an application-specific way. In this paper, we focus on Mobile Wireless Sensor Networks, which are specific opportunistic networks because of their poor connectivity among the mobile sensors, and thus it is difficult to form a well connected mesh network for ...

On the lifetime of large scale sensor networks

Computer Communications, 2006
Network lifetime is an important metric for battery operated sensor networks. In this paper, we study the lifetime of a large scale sensor network with n randomly deployed sensors communicating with a base station (BS), where each sensor node has the same probability to sense and report its data to the BS.

On sensor network lifetime and data distortion

Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005
Fidelity is one of the key considerations in data collection schemes for sensor networks. A second important consideration is the energy expense of achieving that fidelity. Data from multiple correlated sensors is collected over multi-hop routes and fused to reproduce the phenomenon.

A new genetic-based approach for maximizing network lifetime in directional sensor networks with adjustable sensing ranges

Pervasive and Mobile Computing, 2019
In recent years, the directional sensor networks have been attractive to researchers due to their wide and different applications. These networks normally contain a number of self-configurable directional sensors holding adjustable spherical sectors with

Revisiting the lifetime of wireless sensor networks

Proceedings of the 2nd international conference on Embedded networked sensor systems, 2004
Prolonging the lifetime of wireless sensor networks (WSN) is one of the most important goals in the sensor network research. A lot of work has been done to achieve this goal; however, current definition of lifetime is either superficial or impractical.

Data censoring with network lifetime constraint in wireless sensor networks

Digit. Signal Process., 2019
In wireless sensor networks (WSNs), senor nodes are usually battery-powered with limited energy budget. The network lifetime is directly related to the energy consumption of each node.
