Online algorithms for maximizing quality of link transmissions over a jammed wireless channel
Found in: Pervasive Computing and Communications, IEEE International Conference on
By Rajgopal Kannan, Shuangqing Wei, Costas Busch, Athanasios Vasilakos
Issue Date:March 2009
pp. 1-6
We consider the problem of a transmitter transmitting to its receiver over a wireless link subject to jamming and develop two online power control algorithms for maximizing wireless link quality (transmission rate). We assume that the transmitter transmits...
A Measurement Study of Unstructured P2P Overlay
Found in: Computer Science and Software Engineering, International Conference on
By Jiaqi Liu, Zhigang Chen, Deng Li, Athanasios Vasilakos
Issue Date:December 2008
pp. 121-124
One of the most challenging problems in P2P computing is the difficulty of locating content in an efficient and scalable way. The structured P2P overlay is unsuitable for dynamic environments because users come from non-cooperating organizations with highl...
Local Area Prediction-Based Mobile Target Tracking in Wireless Sensor Networks
Found in: IEEE Transactions on Computers
By Md Zakirul Alam Bhuiyan,Guojun Wang,Athanasios Vasilakos
Issue Date:August 2014
pp. 1
Tracking mobile targets in wireless sensor networks (WSNs) has many important applications. As it is often the case in prior work that the quality of tracking (QoT) heavily depends on high accuracy in localization or distance estimation, which is never per...
Interference-based Topology Control Algorithm for Delay-constrained Mobile Ad hoc Networks
Found in: IEEE Transactions on Mobile Computing
By xinming zhang,Yue Zhang,Fan Yan,Athanasios Vasilakos
Issue Date:June 2014
pp. 1
As the foundation of routing, topology control should minimize the interference among nodes, and increase the network capacity. With the development of mobile ad hoc networks (MANETs), there is a growing requirement of quality of service (QoS) in terms of ...
Multiobjective Communication Optimization for Cloud-Integrated Body Sensor Networks
Found in: 2014 14th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing (CCGrid)
By Dung H. Phan,Junichi Suzuki,Shingo Omura,Katsuya Oba,Athanasios Vasilakos
Issue Date:May 2014
pp. 685-693
This paper focuses on push-pull hybrid communication in a cloud-integrated sensor networking architecture, called Sensor-Cloud Integration Platform as a Service (SC-iPaaS). SC-iPaaS consists of three layers: sensor, edge and cloud layers. The sensor layer ...
ACE: An Accurate and Efficient Multi-Entity Device-Free WLAN Localization System
Found in: IEEE Transactions on Mobile Computing
By Ibrahim Sabek,Moustafa Youssef,Athanasios Vasilakos
Issue Date:May 2014
pp. 1
Device-free (DF) localization in WLANs has been introduced as a value-added service that allows tracking of indoor entities that do not carry any devices. Previous work in DF WLAN localization focused on the tracking of a single entity due to the intractab...
Reliable Multicast with Pipelined Network Coding using Opportunistic Feeding and Routing
Found in: IEEE Transactions on Parallel and Distributed Systems
By Peng Li,Song Guo,Shui Yu,Athanasios Vasilakos
Issue Date:March 2014
pp. 1
Multicast is an important mechanism in modern wireless networks and has attracted significant efforts to improve its performance with different metrics including throughput, delay, energy efficiency, etc. Traditionally, an ideal loss-free channel model is ...
Information sharing in bee colony for detecting multiple niches in non-stationary environments
Found in: Proceeding of the fifteenth annual conference companion on Genetic and evolutionary computation conference companion (GECCO '13 Companion)
By Athanasios Vasilakos, Souvik Kundu, Subhodip Biswas, Swagatam Das
Issue Date:July 2013
pp. 1-2
This paper proposes an information sharing model of artificial bee colony for locating multiple peaks in dynamic environments. The concept of niching is implemented by using a hybridized approach that combines a modified variant of the fitness sharing tech...
