Security in wireless ad-hoc networks – A survey

Computer Communications, 2014
Pervasive mobile and low-end wireless technologies, such as radio-frequency identification (RFID), wireless sensor networks and the impending vehicular ad-hoc networks (VANETs), make the wireless scenario exciting and in full transformation. For all the above (and similar) technologies to fully unleash their potential in the industry and society, there

Routing and scheduling in wireless ad hoc networks

2009 IEEE International Workshop on Intelligent Data Acquisition and Advanced Computing Systems: Technology and Applications, 2009
Computing capacity bounds of ad hoc networks, as well as optimizing radio resource allocation in order to approach those bounds is a hard task that have recently attracted the interest of the research community. In this paper we address the problem of jointly optimizing the routing of flows, the transmission scheduling over wireless links along the ...

Wireless Ad Hoc Networks

2011
Seamless communication between computing devices is an essential part of the new world of ubiquitous computing. To achieve the concept of a “disappearing computer,” it is necessary to establish reliable and simple communication principles to enhance the usability and the efficiency of the ubiquitous computing devices.

Coverage in wireless ad-hoc sensor networks

2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003
Sensor networks pose a number of challenging conceptual and optimization problems such as location, deployment, and tracking. One of the fundamental problems in sensor networks is the calculation of the coverage. In Meguerdichian et al. (2001), it is assumed that the sensor has uniform sensing ability.

Growth of wireless ad hoc networks

GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004
The utility of a node in an energy-limited wireless ad hoc network is defined as a positive linear function of the number of bits that the node sends as a source and the number of bits that it receives as a destination. First, we show that under the one-to-one traffic model in which every node wants to send traffic to a randomly chosen destination node,

Ad Hoc Wireless Networks

2004
Ad hoc networks offer a radical alternative to existing cellular and fixed networks for providing communications. These networks form on the fly from the communications devices themselves without needing any infrastructure or centralised control. Devices communicate directly with each other and by forming chains of transceivers they relay information ...

An Integrated Model of Wireless ad hoc Networks

International Journal of Modelling and Simulation, 2006
The author proposes a time-invariable, integrated model of wireless networks working in a hostile environment with obstructions and other factors causing interference. The work presents a new probabilistic model and shows a number of simulation results, which confirm the usefulness of the model in the mean-case analysis.

Ad–hoc Filesystem: A Novel Network Filesystem for Ad-hoc Wireless Networks

2001
In this paper, we propose a new filesystem named Ad-hoc Filesystem which targets ad-hoc wireless networks. Ad-hoc Filesystem is a serverless filesystem which automatically generates temporary shared space among multiple mobile machines when they gather in a communicable range. The generated space is kept stable as long as possible even if some machines

Wireless Ad Hoc Networking

2005
Mobile ad hoc networks represent a new form of communication consisting of mobile wireless terminals (e.g., handset, PDAs, notebooks). These type of networks are wireless multi-hop packet networks without any fixed infrastructure and centralized administration, in contrast to today’s wireless communications, which is based on a fixed, pre-established ...
