Special Issue on Multimedia over Ad-Hoc and Sensor Networks

摘要

With the increased reliance of our modem society on communication infrastructures and the migration towards all-IP next generation networks, research and development activities must aim at providing stable and reliable broadband communication infrastructures and provisioning of new types of multimedia applications even under extreme situations. Existing wireless communication systems, such as 3G cellular networks and WLANs, are infrastructure based and often do not provide alternative communication paths, which instead are important in case the wireline/wireless infrastructure is damaged or heavily congested. Additionally, these solutions require increased capital investments and leading time for their deployment. These reasons gave birth to an increased interest for ad hoc and sensor networks, which represent network solutions that may be deployed in places where no any infrastructures are present but communications are required and the moving nodes may be considered as the "infrastructure" for these networks.
