Extending Network Lifetime of Wireless Sensor Networks
One critical issue in designing and managing a wireless sensor network is how to save the energy consumption of the sensors in order to maximize network lifetime under the constraint of full coverage of the monitored targets. In this paper, we adopt the common approach of creating disjoint sensor covers to prolong network lifetime. The typical goal used in the literature is to maximize the numb...
متن کاملExtending the Lifetime of Wireless Sensor Networks
The electricity of sensor nodes in wireless sensor networks is very limited, so it is an important research topic to deploy the sensor nodes and cooperate with an efficient routing algorithm for extending the network lifetime. In the related research, LEACH routing algorithm randomly selects cluster heads in each round to form a cluster network, which may cause additional power consumption and ...
متن کاملPredicting and Extending of Sensor Lifetime in Wireless Sensor Networks using Fuzzy Logic
Wireless sensor networks are specially distributed autonomous sensor, WSN communicates with signals, the lifetime of a sensor mainly depends on the energy or battery of a sensor nodes. Cluster is a set of sensor nodes which communicates with each other in a range. Cluster formation and cluster head selection are important problems in Wireless Sensor Networks (WSNs). They can drastically affect ...
متن کاملLocal Repair for Extending Lifetime of Wireless Sensor Networks
188 Abstract-The lifetime of battery operated wireless sensor networks can be prolonged by energy aware maintenance of the virtual backbone. The energy of a node is depleted quickly during communication and network failure is most likely to occur when the energy of a Minimum Connected Dominating Set (MCDS) node is exhausted. The reconstruction of an alternate backbone without the depleted node ...
متن کاملAn Approach to Extending the Lifetime of Wireless Sensor Networks
Wireless Sensor Networks (WSNs) are energy constrained. Every operation, particularly the use of radio, reduces the energy reserves of nodes. The aim of this work is to improve the useful network lifetime of a WSN, which we define as being from the time when the network is activated to the time at which it is no longer able to carry out its assigned task. Routing protocols try to preserve lifet...
