This Phase II SBIR effort will build and demonstrate full-scale prototypes of the nomadic router, a network function that can be implemented either in hardware or within the software of mobile wireless computers. The nomadic router allows a collection of such wireless computers to organize themselves into a multi-hop wireless network without the aid of any established infrastructure or centralized administration and without any user-initiated configuration actions. Such rapidly deployable networks are ideal for addressing the needs of a wide range of tactical applications envisioned by the military for the digital battlefield of tomorrow. The prototype nomadic router will incorporate several innovative ideas whose feasibility was established by the Phase I effort. Innovations include 1) a novel routing protocol called Source-Initiated Adaptive Routing Algorithm (SARA) whose performance and capabilities to support a wide range of tactical network environments is unmatched by existing routing protocols; 2) a multicast routing protocol for ad hoc networks; and 3) a QoS adaptive video multicast service to support emerging multimedia applications in the battlefield. The Phase II effort will demonstrate two alternative implementations of the nomadic router: A software product and an add-on PC card for mobile wireless nodes.
