Active node determination for correlated data gathering in wireless sensor networks
(Elsevier BV, 2013-04-07)In wireless sensor network applications where data gathered by different sensor nodes is correlated, not all sensor nodes need to be active for the wireless sensor network to be functional. Given that the sensor nodes that ... -
An adaptive, energy-aware and distributed fault-tolerant topology-control algorithm for heterogeneous wireless sensor networks
(Elsevier BV, 2016)This paper introduces an adaptive, energy-aware and distributed fault-tolerant topology-control algorithm, namely the Adaptive Disjoint Path Vector (ADPV) algorithm, for heterogeneous wireless sensor networks. In this ... -
A comparison of epidemic algorithms in wireless sensor networks
(Elsevier BV, 2006-08-21)We consider the problem of reliable data dissemination in the context of wireless sensor networks. For some application scenarios, reliable data dissemination to all nodes is necessary for propagating code updates, queries, ... -
Computing localized power-efficient data aggregation trees for sensor networks
(Institute of Electrical and Electronics Engineers, 2011)We propose localized, self organizing, robust, and energy-efficient data aggregation tree approaches for sensor networks, which we call Localized Power-Efficient Data Aggregation Protocols (L-PEDAPs). They are based on ... -
Coordinated movement of multiple mobile sinks in a wireless sensor network for improved lifetime
(SpringerOpen, 2015)Sink mobility is one of the most effective solutions for improving lifetime and has been widely investigated for the last decade. Algorithms for single-sink mobility are not directly applied to the multiple-sink case due ... -
Distributed and location-based multicast routing algorithms for wireless sensor networks
(SpringerOpen, 2009-01)Multicast routing protocols in wireless sensor networks are required for sending the same message to multiple different destinations. In this paper, we propose two different distributed algorithms for multicast routing in ... -
Distributed construction and maintenance of bandwidth and energy efficient bluetooth scatternets
(Institute of Electrical and Electronics Engineers, 2006-09)Bluetooth networks can be constructed as piconets or scatternets depending on the number of nodes in the network. Although piconet construction is a well-defined process specified in Bluetooth standards, scatternet formation ... -
Distributed interactive video system design and analysis
(Institute of Electrical and Electronics Engineers, 1997)The interactive video (IV) market has been expected to capture a significant share of the huge potential revenues to be generated by the business and residential markets. The level of revenues generated depends on the ... -
Distributed joint flow-radio and channel assignment using partially overlapping channels in multi-radio wireless mesh networks
(Springer, 2016)Equipping mesh nodes with multiple radios that support multiple wireless channels is considered a promising solution to overcome the capacity limitation of single-radio wireless mesh networks. However, careful and intelligent ... -
Distributed k-Core view materialization and maintenance for large dynamic graphs
(Institute of Electrical and Electronics Engineers, 2014-10)In graph theory, k-core is a key metric used to identify subgraphs of high cohesion, also known as the ‘dense’ regions of a graph. As the real world graphs such as social network graphs grow in size, the contents get ... -
Distributed power-source-aware routing in wireless sensor networks
(Springer New York LLC, 2016)Although many applications use battery-powered sensor nodes, in some applications battery- and mains-powered nodes coexist. In this paper, we present a distributed algorithm that considers using mains-powered devices to ... -
A distributed tault-tolerant topology control algorithm for heterogeneous wireless sensor networks
(Institute of Electrical and Electronics Engineers, 2015-04)This paper introduces a distributed fault-tolerant topology control algorithm, called the Disjoint Path Vector (DPV), for heterogeneous wireless sensor networks composed of a large number of sensor nodes with limited energy ... -
Effects of physical channel separation on application flows in a multi-radio multi-hop wireless mesh network: an experimental study on BilMesh testbed
(Academic Press, 2014)In this paper, we introduce BilMesh, an indoor 802.11 b/g mesh networking testbed we established, and we report about our performance experiments conducted on multi-hop topologies with single-radio and multi-radio relay ... -
Efficient community identification and maintenance at multiple resolutions on distributed datastores
(Elsevier BV, 2015)The topic of network community identification at multiple resolutions is of great interest in practice to learn high cohesive subnetworks about different subjects in a network. For instance, one might examine the ... -
Energy efficient IP-connectivity with IEEE 802.11 for home M2M networks
(Oxford University Press, 2017)Machine-to-machine communication (M2M) technology enables large-scale device communication and networking, including home devices and appliances. A critical issue for home M2M networks is how to efficiently integrate ... -
A framework for use of wireless sensor networks in forest fire detection and monitoring
(Elsevier Ltd., 2012)Forest fires are one of the main causes of environmental degradation nowadays. Current surveillance systems for forest fires lack in supporting real-time monitoring of every point of a region at all times and early detection ... -
Free riding in peer-to-peer networks
(Institute of Electrical and Electronics Engineers, 2009)Free riding in peer-to-peer (P2P) networks poses a serious threat to their proper operation. Here, the authors present a variety of approaches developed to overcome this problem. They introduce several unique aspects of ... -
Network-aware virtual machine placement in cloud data centers with multiple traffic-intensive components
(Elsevier BV, 2015)Following a shift from computing as a purchasable product to computing as a deliverable service to consumers over the Internet, cloud computing has emerged as a novel paradigm with an unprecedented success in turning utility ... -
A novel measurement-based approach for modeling and computing interference factors for wireless channels
(SpringerOpen, 2013)Wireless communication technologies divide their available spectrum into pre-defined channels. Some wireless technologies, such as the IEEE 802.11b/g, define their channels in such a way that adjacent channels share the ... -
