Lifetime optimization for Wireless Sensor Networks

2009 IEEE/ACS International Conference on Computer Systems and Applications, 2009
In a Wireless Sensor Network (WSN), nodes are battery powered, therefore, there are energy constrained. Network lifetime is one of the most important characteristics of performance for wireless sensor networks. A number of routing schemes, energy efficient and energy-aware, have been proposed to maximize the network lifetime.

Upper bounds on the lifetime of sensor networks

ICC 2001. IEEE International Conference on Communications. Conference Record (Cat. No.01CH37240), 2002
We ask a fundamental question concerning the limits of energy efficiency of sensor networks-what is the upper bound on the lifetime of a sensor network that collects data from a specified region using a certain number of energy-constrained nodes? The answer to this question is valuable for two main reasons.

Node Lifetime - Network Lifetime Tradeoff for Data Gathering Trees in Wireless Sensor Networks

Proceedings of the International Conference on Intelligent Information Processing, Security and Advanced Communication, 2015
We study the performance of the bottleneck node weight-based data gathering trees (BNW-DG) and bottleneck link weight-based data gathering (BLW-DG) trees in wireless sensor networks (WSNs) through extensive simulations. The BNW-DG trees incur a smaller diameter and a significantly larger fraction of nodes as leaf nodes; whereas the BLW-DG trees incur a

Lifetime Maximization in Wireless Sensor Networks

International Journal of Wireless Networks and Broadband Technologies, 2011
One of the fundamental requirements in wireless sensor networks (WSNs) is to prolong the lifetime of sensor nodes by minimizing the energy consumption. The information about the energy status of sensor nodes can be used to notify the base station about energy depletion in any part of the network.

Lifetime Analysis in Heterogeneous Sensor Networks

9th EUROMICRO Conference on Digital System Design (DSD'06), 2006
Wireless sensor networks (WSN) are composed of battery-driven communication entities performing multiple, usually different tasks. In order to complete a given task, all sensor nodes, which are deployed in an ad-hoc fashion, have to collaborate by exchanging and forwarding measurement data.

Evaluation of lifetime in wireless sensor networks

2011 IEEE 36th Conference on Local Computer Networks, 2011
In this paper, we propose methods to derive from original model, bounding models family for computation of lifetime in Wireless sensor networks. These models allow to find trade-off between accuracy of the bounds and the computation complexity.

Predicting route lifetime for maximizing network lifetime in MANET

2012 International Conference on Computing, Electronics and Electrical Technologies (ICCEET), 2012
In wireless networks, generally nodes operate with batteries for its own normal operation like mobility, packet forwarding. These nodes tend to drain their energy even when it remains in idle mode. In MANETs, this exhaustion of energy will be more due to its infrastructureless nature and mobility.

Improving network lifetime with mobile wireless sensor networks

Computer Communications, 2010
Sensors are used to monitor and control the physical environment. In mobile sensor networks, nodes can self-propel via springs, wheels, or they can be attached to transporters, such as vehicles. Sensors have limited energy supply and the sensor network is expected to be functional for a long time, so optimizing the energy consumption to prolong the ...

Limiting the lifetime of packets in computer networks

Computer Networks (1976), 1979
Abstract The assurance mechanisms of end-to-end protocols used in packet-switching computer networks rely on implicit or explicit assumptions about the maximum lifetime of packets being transported from origin to destination. However, some parts of networks may hold packets for arbitrary periods but not report how long they are held.
