  • Base Station Location -Aware Optimization Model of the Lifetime of Wireless Sensor Networks.pdf.jpg
  • Article


  • Authors: Nguyen, Thanh Tung; Huynh, Thi Thanh Binh (2015)

  • Recently, wireless sensor networks (WSNs) have been progressively applied in various fields and areas. However, its limited energy resources is indisputably one of the weakest point that strongly affects the network’s lifetime. A WSN consists of a sensor node set and a base station. The initial energy of each sensor node will be depleted continuously during data transmission to the base station either directly or through intermediate nodes, depending on the distance between sending and receiving nodes. This paper consider determining an optimal base station location such that the energy consumption is kept lowest, maximizing the network’s lifetime and propose a nonlinear pr...

  • Article


  • Authors: Phan, Tan; Nguyen, Thanh Tung; Vu, Khanh Hoan; Tran, Viet Trung; Nguyen, Huu Duc (2017)

  • So far, medical data have been used to serve the need of people’s healthcare. In some countries, in recent years, a lot of hospitals have altered the conventional paper medical records into electronic health records. The data in these records grow continuously in real time, which generates a large number of medical data available for physicians, researchers, and patients in need. Systems of electronic health records share a common feature that they are all constituted from open sources for Big Data with distributed structure in order to collect, store, exploit, and use medical data to track down, prevent, treat human’s diseases, and even forecast dangerous epidemics.

  • Coalgebraic Aspects of Context-Awareness.PDF.jpg
  • Article


  • Authors: Phan, Cong Vinh; Nguyen, Thanh Tung (2013)

  • This paper will be both to give an in-depth analysis as well as to present the new material on the notion of context-aware computing, an idea that computing can both sense and react accordantly based on its environment. The paper formalizes context-awareness process using coalgebraic language, including the coalgebraic definition of context-awareness, bisimulation between context-awarenesses, homomorphism between context-awarenesses and context-awarenesses as coalgebras. Discussions for further development based on this approach are also given.

  • The Energy-Aware Operational Time of Wireless Ad-HocSensor Networks.pdf.jpg
  • Article


  • Authors: Nguyen, Thanh Tung; Phan, Cong Vinh (2013)

  • Sensor networks are deployed in numerous military and civil applications, such as remote target detection, weather monitoring, weather forecast, natural resource exploration and disaster management. Despite having many potential applications, wireless sensor networks still face a number of challenges due to their particular characteristics that other wireless networks, like cellular networks or mobile ad hoc networks do not have. The most difficult challenge of the design of wireless sensor networks is the limited energy resource of the battery of the sensors. This limited resource restricts the operational time that wireless sensor networks can function in their applicati...

  • Functional Stream Derivatives of Context-Awareness on P2P Networks.PDF.jpg
  • Article


  • Authors: Phan, Cong Vinh; Nguyen, Thanh Tung; Nguyen, Van Phuc; Nguyen, Hai Thanh (2012)

  • This paper will be both to give an in-depth analysis as well as to present the new material on the notion of context-awareness process on P2P networks, an idea that networking can both sense and react accordantly based on external actions. The paper formalizes context-awareness process using the notion of functional stream derivative, including P2P networks, context-awareness and the functional stream derivatives of context-awareness on P2P networks. A brief summary of this approach is also given.

  • Optimizing the operating time of wireless sensor network.PDF.jpg
  • Article


  • Authors: Nguyen, Thanh Tung; Nguyen, Van Duc (2012)

  • A difficult constraint in the design of wireless sensor networks (WSNs) is the limited energy resource of the batteries of the sensors. This limited resource restricts the operating time that WSNs can function in their applications. Routing protocols play a major part in the energy efficiency of WSNs because data communication dissipates most of the energy resource of the networks. There are many energy-efficient cluster-based routing protocols to deliver data from sensors to a base station. All of these cluster-based algorithms are heuristic. The significant benefit of heuristic algorithms is that they are usually very simple and can be utilized for the optimization of large sensor n...

  • Power-Aware Routing for Underwater Wireless Sensor Network.PDF.jpg
  • Article


  • Authors: Nguyen, Thanh Tung; Nguyen, Sy Minh (2014)

  • Water covers more than 70 % of the entire planet, contains much of its natural resources. With the increasing use of underwater sensors for the exploitation and monitoring of vast underwater resources, underwater wireless sensor network (UWSN), mostly based on acoustic transmission technologies, have been developing steadily in terms of operation range and data throughput. In an energy-constrained underwater system environment it is very important to find ways to improve the life expectancy of the sensors. Compared to the sensors of a terrestrial Ad Hoc Wireless Sensor Network (WSN), underwater sensors cannot use solar energy to recharge the batteries, and it is difficult to replace t...
