Error-resilience in multimedia applications over ad-hoc networks

Ad-hoc networking has been of increasing interest in recent years. It encapsulates the ultimate notion of ubiquitous communications with the absence of reliance on any existing network infrastructure. This paper presents a concept for robust operation of multimedia applications over such networks. Error resilient communication is achieved by using a new error detection and concealment technique that exploits information from the decoded image data itself as well as using information from the underlying network. This approach unifies information from both traditional computer science and signal processing domains. A layered architecture framework for the implementation of the proposed system is also described
