Filtered Coherent Thomson Scattering for Plasma Diagnostics

Not Available Ad-hoc networking encompasses communication environments with highly reconfigurable topology. This model is well suited for military communications. Previous work in this area concentrated on either data or voice commu-nications, without an attempt to integrate the different traffic types. Multimedia communications is a central mode of operation for many of today's applications, both for military and commercial markets. For instance, projects such as Global Awareness or Digitized Battlefield require many different and differing traffic streams to be conveyed over the same tactical network. These different traffic streams are characterized by different requirements, such as delay, jitter, bit error rate, outage probability, etc. Quality-of-Service (QoS) metrics attached to different traffic types, and effective methods for utilizing these metrics in routing and multimedia algorithms, do not yet provide adequate solutions to these problems. This proposal addresses exactly this issue - provision of QoS in the ad-hoc communication environment to support multimedia traffic. In particular, we will study: 1) QoS needs and requirements for DoD's tactical applications, 2) previously proposed and implemented schemes to support QoS in both fixed and wireless networks, 3) incorporation of QoS parameters into ad-hoc networks, 4) effective link-sensing techniques for QoS-based routing, and 5) how Alternate Path Routing can be employed within ad-hoc networks.
