Abstract: Mayflower Communications Company, Inc. (Mayflower) proposes a Topology Management technology, the Prioritized Unbalanced Traffic Total Yield (PUTTY), to meet the Navy objective, namely, to develop advanced approaches for readily deployable Topology Management algorithms that address the complexity of mobile Ad Hoc Mesh Communication Networks constructed of directional antennas, and demonstrate its ability to optimize total network carrying capacity in a tactical ad hoc environment with unbalanced traffic. The proposed PUTTY topology management includes (1) network monitoring and analysis algorithms, and (2) network topology optimization algorithms. These two categories of topology management algorithms are applied repeatedly to dynamically optimize the network topology. Low complexity of the algorithms ensures that the proposed topology management is able to manage networks with hundreds of heterogeneous nodes. The proposed PUTTY technology leverages Mayflower's expertise in network design and topology management, and builds on technology developed under several SBIR programs and Internal R&D. The PUTTY system, when proven feasible in the Phase I study for the Navy application, has enormous potential for military and commercial applications. Mayflower will develop a prototype PUTTY system in Phase I and II, and ensure its commercialization in Phase III and beyond.
Benefits: By providing dynamic topology management, PUTTY can help complex tactical networks such as the Navy FORCEnet and the Army Warfighter Information Network-Tactical (WIN-T) achieve high level of performance, and thus be a key enabler in Network-Centric Warfare. In the commercial arena, PUTTY can enable efficient networking for metropolitan heterogeneous networks consisting of diverse wireless devices such as WiFi, WiMAX, Bluetooth and 3G cellular. PUTTY can also provide dynamic topology management services for first responder networks, and therefore enable efficient setup and management of such networks in disaster recovery scenarios.
