Diminutive devices and high clock frequency of future microprocessor generations are causing increased concerns for transient soft failures in hardware, necessitating fault detection and recovery mechanisms even in commodity processors. In this paper, we p ...
Terminode routing, defined for potentially very large mobile ad hoc networks, forwards packets along anchored paths. An anchored path is a list of fixed geographic points, called anchors. Given that geographic points do not move, the advantage to tradition ...
For some time now, the design of architectures for providing dependable Quality of Service (QoS) on multimedia networks has been a busy topic in academia and industry. In this work we look at practical aspects of Quality of Service, and in particular at re ...
We discuss the limitations of conventional closed loop power control (CLPC). We derive a closed-form expression for the control error. We then propose two algorithms that reduce this error. Simulations show a reduced power error compared to current CLPC te ...

A spread interleaver of length N is a semi-random interleaver based on the random selection without replacement of N integers from 1 to N under a design constraint. This paper extends the spread-interleaver design method to multiple error events, based on ...
Real-time audio over the best effort Internet often suffers from packet loss. So far, Forward Error Correction (FEC) seems to be an efficient way to attenuate the impact of loss. Nevertheless to ensure efficiency of FEC, the source rate must be continuousl ...
In this paper, the performances of packet-level media-independent FEC schemes are computed in terms of both packet loss ratio and average burst length of multimedia data after error recovery. The set of equations leading to the analytical formulation of bo ...

The theory and practice of digital communication during the past 50 years has been strongly influenced by Shannon's separation theorem. While it is conceptually and practically appealing to separate source from channel coding, either step requires infinite ...
