Configurable Internet Sub-Protocol for Sensor Networks and State Space Aware Adaptive Routing Navy SBIR FY2005.2 Sol No.: Navy SBIR FY2005.2 Topic No.: N05-108 Topic Title: Configurable Internet Sub-Protocol for Sensor Networks and State Space Aware Adaptive Routing Proposal No.: N052-108-0146 Firm: Nova Engineering, Inc. 5 Circle Freeway Drive Cincinnati, Ohio 45246-1201 Contact: Ken Fischer Phone: (513) 554-2046 Web Site: http://www.nova-eng.com Abstract: The migration of MANET protocols to networks supporting fast movers has been problematic, due to the network dynamics caused by fast moving aircraft in the network. The amount of overhead traffic required to maintain connectivity in these networks is often intolerable. Nova proposes two methods for reducing the network overhead burden. First, a communications extension for efficient distribution of small network packets will be developed under this effort. The protocol will be designed as a portable software module, which is seamlessly inserted between the network routing and wireless interface driver. With this software component, each node will have the capability to dynamically negotiate the use of a subchannel over standard IP, while still retaining full support for the distribution of IPv4/IPv6 messages. To reduce the raw amount of network overhead required, Nova also proposes technologies that will equip each node with a better sense of its location and role in a network. This will be facilitated by the exchange of position, velocity, and time information around the network, and by passive sensing of link quality through advanced cross-layer techniques. Both technologies are proposed as extensions to IETF standard protocols, which will ensure the viability of these technologies' deployment and acceptance. Benefits: MANET networking is a very promising technology that enables highly connected networks to be established in areas void of the traditionally required communications infrastructure. The CIPS/SSAAR protocol extends existing MANET protocols to reduce problems that occur during network hand-offs. Following Phase II, Nova will market the enhancements in both the commercial and military markets. Nova will embed the CIPS and SSAAR technologies in its NovaRoam commercial-off-the-shelf radio product. Our experience in the commercial market indicates the features of the CIPS/SSAAR protocol will provide a highly valuable market discriminator. With the DoD's increasing reliance on networked communications, it is anticipated that technologies developed on this SBIR will migrate to WIN-T and JTRS, due to the technology's promise in enhancing communications connectivity.
