S-XTC: A Signal-Strength Based Topology Control Algorithm
(2005)TIK ReportWe present S-XTC, a topology control algorithm that uses the received signal strength indicator (RSSI) of the radio on the sensor nodes. The algorithm is based on XTC, an simple topology control algorithm that constructs a relative neighborhood graph. In contrast to XTC our extended Version is robust against an error-prone RSSI. It guarantees the connectivity and a bounded degree and is able to adapt to Network changes. We discuss the ...Report -

Media- and TCP-Friendly Congestion Control for Scalable Video Streams (Extended Version)
(2005)TIK ReportAbstract. This paper presents a Media- and TCP-Friendly Rate-based Congestion Control algorithm (MTFRCC) for scalable video streaming in the Internet. The algorithm integrates two new techniques: (i) the use of a utility-based model for the target system combined with the rate-distortion function as the application utility measure for optimizing the overall video quality; and (ii) a two-timescale approach of rate averages (long-term and ...Report -
Timed Automata Templates for Distributed Embedded System Architectures
(2005)TIK ReportNetworks of timed automata can be used to specify and verify distributed embedded systems. This technical report provides timed automata templates for a few basic components of such systems as a first step towards a library of reusable components which shall facilitate the design and analysis of large distributed embedded systems. In particular timed automata templates for common input event streams and for TDMA-scheduling are provided.Report
