Energy-efficient distributed clustering in wireless sensor networks
(2010)The deployment of wireless sensor networks in many application areas requires self-organization of the network nodes into clusters. Clustering is a network management technique, since it creates a hierarchical structure ... -
Investigating Wireless Sensor Network lifetime under static routing with unequal energy distribution
(2012)In a Wireless Sensor Network (WSN) the sensed data must be gathered and transmitted to a base station where it is further processed by end users. Since that kind of network consists of low-power nodes with limited battery ... -
Lifetime maximization in wireless sensor networks with an estimation mission
(2009)We study the problem of maximum lifetime in wireless sensor networks that are entitled with the task of estimating an unknown parameter or process. Sensors take measurements and transfer them in multi-hop fashion to a ... -
Measurement aggregation and routing techniques for energy-efficient estimation in wireless sensor networks
(2010)Wireless sensor networks are fundamentally different from other wireless networks due to energy constraints and spatial correlation among sensor measurements. Mechanisms that efficiently compress and transport sensor data ... -
Minimum weighted clustering algorithm for wireless sensor networks
(2015)Extending network lifetime is a primary design objective for a wireless sensor network (WSN). Efficient clustering among sensor nodes seems a promising solution to evenly balance energy consumption and thus extend node and ... -
Sensor Placement for Lifetime Extension by Applying Neural Network Configuration under Coverage and Energy Constraints
(2022)In deployments of Wireless Sensor Networks (WSNs), sensor placement, coverage, connectivity and energy constraints determine the overall network lifetime. In large-size WSNs it is difficult to maintain a trade-off among ... -
Topology control with coverage and lifetime optimization of wireless sensor networks with unequal energy distribution
(2017)In this work, we use an unequal energy distribution algorithm, with which we succeed to extend network lifetime. In the sequel, we, we provide the best effort coverage by arranging the nodes using topology control principles. ... -
Transmit rate control for energy-efficient estimation in wireless sensor networks
(2010)We study the impact of physical layer (PHY) transmit rate control on energy efficient estimation in wireless sensor networks. A sensor network collects measurements and transmits them to a Fusion Center (FC) with controllable ...
