Communications in Digital Battlefield: Fundamental Problems in the Design of Hetrogeneous Networks
Abstract
The research for this grant is on fundamental problems in the design of heterogeneous networks, including high level wireless link modeling, resource negotiation, and end-to-end transport. TCP, the de facto standard for Interment data transport protocol, is not robust to lossy wireless links. However, it has been shown that it is possible to support TCP by hiding the wireless loss from it using link layer error recovery. Also, alternatives transport protocol have been investigated, which solve the congestion control and error recovery problems of TCP. Quality of Service (QoS) for real time data have also been investigated. Choice of forward error control (FEC) and adaptation to the channel have been shown to improve the QoS provided. Also, a generalized round robin scheduler has been shown to provide the same QoS at lower complexity. Note: the PI has moved from University of Illinois to University of California Santa Barbara, where he is continuing his work under a new grant.
