Abstract:

The Multipurpose Surveillance and Security Mission Platform MSSMP is a distributed network of remote sensing packages and control stations, designed to provide a rapidly deployable, extended-range surveillance capability for a wide variety of military security operations and other tactical missions. The baseline MSSMP sensor suite consists of a pantilt unit with video and FLIR cameras and laser imageflnder. With an additional radio transceiver, MSSMP can also function as a gateway between existing securitysurveillance sensor systems such as TASS, TRSS, and IREMBASS, and IP-based networks, to support the timely distribution of both threat detection and threat assessment information. The MSSMP system makes maximum use of Commercial Off The Shelf COTS components for sensing, processing, and communications, and of both established and emerging standard communications networking protocols and system integration techniques. Its use of IP-based protocols allows it to freely interoperate with the Internet- providing geographic transparency, facilitating development, and allowing fully distributed demonstration capability - and prepares it for integration with the IP-based tactical radio networks that will evolve in the next decade. Unfortunately, the Internets standard Transport layer protocol, TCP, is poorly matched to the requirements of security sensors and other quasi-autonomous systems in being oriented to conveying a continuous data stream, rather than discrete messages. Also, its canonical socket interface both conceals short losses of communications connectivity and simply gives up and forces the Application layer software to deal with longer losses. For MSSMP, a software applique is being developed that will run on top of User Datagram Protocol UDP to provide a reliable message-based Transport service.
