Flood6
Flood6 is an application middleware and proxy designed for applications to use optimized flooding (e.g. S-MPR, E-CDS, MPR-CDS), and for efficient one to many communication in Wireless Multi-hop Network. Using API provided by flood6, applications can easily select and use optimized flooding for a content distribution method. In addition, flood6 has novel extentions such as dynamic bit rate control for streaming content such as video and audio. Details of this functionality is described in [AINTEC]. Flood6 is one of the core implementation of Segwaynet Project and is used as a base system of Push To Talk application in Open Research Forum 2006 at Tokyo. Demonstration of Flood6 can be seen latter part of Segwaynet Demo Video.

Flooding Messenger
Flooding messenger is designed for distance-based group communication in Wireless Multi-hop Networks. Flooding messenger is a text communication tool. It limits distribution area of each message within 3-4 hop neighbor nodes. In addition to this characteristic, flooding messenger changes font size of each message depending on hop count so that user can know distance between user and a sender. Flooding messenger is used in "Internet Technology Workshop 2005, 2006" lectured by Ryuji Wakikawa and demonstrated in Segwaynet Project.

Music and Flush Streamer
Music and Flush Streamer (MFS) is a streaming application focuses on improving realistic sensation for remote clients. For such improvements, MFS server controls (flush) remote strobe with signal as well as music streaming. MFS client plays received music stream and turns on/off strobe depending on storobe signal from MFS server.
Following link is demonstration video for MFS (only japanese): Demo.
DV Stream Control Proxy
DV Stream Control Proxy (DSCP) is used as an application proxy for Digital Video Transport System (DVTS). DSCP can convert bit rate of DV data and change transmission method, for example converting unicast stream to multicast stream, when transmitting DV data. DSCP is proposed and demonstrated in [DSCP]. DSCP can run on BSD/Linux system.
