— Wireless channels are highly affected by unpredictable factors such as cochannel interference, adjacent channel interference, propagation path loss, shadowing and multipath fading. The un-reliability of media degrades the transmission quality seriously. Forward Error Correction (FEC) schemes are frequently used in wireless environments to reduce the high(More)
Saving power of Android enabled devices have become a significant issue with 400,000 such devices being activated daily. Android smartphones and tablets offer several power hungry hardware components and the app developers are exploiting these components at disposal to provide revolutionary user experience. But the battery life has not increased at the same(More)
This draft describes a specific problem encountered when using RSVP (Resource Reservation Protocol) over optimised routes in MIPv6 (Mobile IP Version 6). The address translation in the MIP's binding cache creates a mismatch between the flow-id of the packets sent from correspondent node to mobile node and the flow-id signalled by RSVP. We discuss several(More)
This paper gives an outline and solutions to the problem of running RSVP signalling in Mobile IP (Mobile Internet Protocol) networks using optimised routing. First, we discuss a basic solution to this problem. By modifying RSVP at mobile and correspondent nodes to become aware of MIPv6 addressing, we provide a simple repair that allows RSVP flows to be(More)
The growth of the Internet community and the trend towards multimedia services changes the Internet Protocol (IP) suite. Simultaneously, users desire to have a high speed wireless access to the Internet. To meet the increased service and mobility needs the traditional IP protocol has been enhanced with advanced mobility and Quality of Service (QoS)(More)
This demonstration<sup>1</sup> highlights the capabilities of the OpenAirInterface platform in terms of Agile RF spectrum-access and rapidly-deployable networking technologies. With respect to application scenarios, the latter target broadband public-safety communications. We demonstrate the real-time baseband and RF capabilities of the platform components(More)
This deliverable explores the need for a Dynamic Channel Allocation (DCA) mechanism in WAND-like systems. In the context of this study, two main approaches are presented: a centralised and a distributed one. The deliverable describes the basic characteristics of both approaches from which possible advantages and disadvantages are extracted. For each(More)
— The paper has two parts: First, we present an overview of the IST WIreless DEployable Network System (WIDENS) Project. This project aims to define an easily deploy-able communication system to be used by emergency services and public safety in general. In this context, users require a communication system that should not depend on pre-existent(More)
Dynamic spectrum access supported by a low-latency wireless sensor network for spectrum usage monitoring is demonstrated using OpenAirInterface platform. The platform performs secondary communications in bands detected as free, thanks to its multi-band capability. With respect to application scenarios, the main target is to address agile broadband public(More)
