Towards a layer-less network architecture — A case from Wireless Sensor Networks
2011
Ad hoc and Wireless Sensor Networks (WSNs) form a challenging domain for existing network protocols and paradigms to fit into. The traditional models conceived for wired networking and adapted for wireless and mobile environments provide an inefficient and ungraceful outcome when exercised against highly dynamic and highly mobile nature of ad hoc wireless sensor networks. Efforts are being made to tweak existing (and sometimes create from scratch) principles and models that can provide a concrete framework for such newer paradigms. The momentum of the traditional layered architecture carried over from the wired networks to infrastructure based wireless networks pushes the same approaches as…
A Multisensor Proposal for Wireless Sensor Networks
2008
Every sensor node in a wireless sensor network (WSN) has a microcontroller, a transmitter/receiver and a sensor. It is able to acquire data from specific point in a real environment and transmit it through the WSN. Sometimes it is useful to gather different type of data from the same place in order to obtain a final result. In the related literature, very few works are about sensing different parameters using a unique sensor. In this paper we propose a Wireless IP multisensor that is able to gather several types of data from the environment and transmit the result of their combination. Our proposal decision has being mainly based on its development costs, its expansion capacity and its flex…
A Note on the Local Minimum Problem in Wireless Sensor Networks
2013
The Local Minimum Problem occurs in geographic routing scenarios. In this paper two solutions to this problem for certain network topologies are proposed. By using the notion of virtual coordinates a theoretical and a practical constructions are presented. A distributed algorithm for the practical approach is proposed.
On Applications of Wireless Sensor Networks
2009
Wireless Sensor Networks (WSN) are ad-hoc networks in which small independent sensor nodes have limited energy, computational resources and wireless communication capabilities. Recently, both academia and industry have shown great interest in the area of Wireless Sensor Networks. This paper focuses on the practical applications in commerce and feasible future employment of WSNs. Continued advances of wireless communication technologies have led to the following fields of applications: habitat and environmental monitoring, security of buildings and property, oil and gas installations, mines and tunnels, emergency medical care, military applications. In the near future WSNs will certainly ent…

CiNetView - Graphic Interface for Wireless Sensor Network Deployment and Monitoring
2010
Reliable communication is crucial for successful deployment of a wireless sensor network. Many environmental factors can affect the performance of radio links, and the deployment of a network without real-time information about link qualities can be a demanding task. This paper describes the CiNetView application that is intended to support the deployment and monitoring of wireless sensor network. CiNetView is based on diagnostic information collected by sensor nodes, and it allows the user to see a graphical presentation of the network topology and to monitor the network diagnostic information in real time.
The Role of ICT Actors and Networks in Development: The Case Study of a Wireless Project in Nepal
2011
The role of ICT actors in the formation and extension of ICT4D projects is important. The actors through their extended network and aligned interest can enhance the effectiveness of the project which in turn enables socioeconomic development opportunities. However, few studies have been conducted to understand the role of these central players. The objective of this paper, therefore, is to address this knowledge gap by conducting a qualitative case study in the Myagdi district in the mountain region of Nepal. In this study we explored the Nepal Wireless Networking Project (NWNP) and examined how an activist started it from one mountain village and gradually extended across more than 150 vil…
Uenighetsdramaturgier
2019
Hvordan kan samtidsteater bli arena, laboratorium og katalysator for «uenighetsfellesskaper» (Iversen, 2014)? I denne artikkelen drøfter jeg teatersituasjonens potensial for uenighetsfellesskap og ser uenighet i forestillinger i relasjon til uenighet om forestillinger før jeg analyserer to eksempler på «uenighetsdramaturgier». I de kontekstsensible analysene undersøker jeg hvordan publikumets interne uenighet kommer til uttrykk, og hvordan det dramaturgisk legges til rette for denne uenigheten.
'A Net of Words: Old English net and max'
2008
Il saggio prende in esame tutte le occorrenze di due parole dell’antico inglese, col significato di ‘rete’, net e max. Numerose sono le occorrenze di net e dei suoi composti; la voce, di origine ie, ricorre in tutte le lingue germaniche antiche. La voce max ha invece un numero limitato di occorrenze ed è priva di confronti diretti in ambito germanico. Ricorre tre volte in antico inglese, tutte nel Colloquio di Ælfric. Si studiano anche gli altri termini per ‘rete’ in antico inglese, le loro accezioni e le loro continuazioni in medio inglese. Il saggio è compreso un volume in onore di Tette Hofstra, già professore ordinario di germanistica, ora emerito, presso l’Università di Groningen, al q…
