- BROAD AGENCY ANNOUNCEMENT (BAA) 03-20 NETWORKING IN EXTREME ENVIRONMENTS SOL: BAA03-20, CLOSING DATE: 1 March 2004 POC: Stephen Griggs, DARPA/ATO E-mail: sgriggs@darpa.mil, FAX: (703) 696-9781 Fax: (703) 696-9781 WEB: http://www.darpa.mil/ato/ E-MAIL: BAA03-20@darpa.mil PROGRAM OBJECTIVES AND DESCRIPTION: The Defense Advanced Research Projects Agency (DARPA) is soliciting abstracts and proposals for DARPA?s Advanced Technology Office (ATO) to perform research, development, design, and testing to support the DARPA Networking in Extreme Environments (NETEX) program. The goal of the NETEX Program is to create ultra-wideband (UWB) sensor and communication systems and support their integration into a wireless networking technology that enables robust connectivity in harsh military environments. This BAA defines an UWB signal as one that at any point in time has a fractional bandwidth equal to or greater than twenty percent or a bandwidth greater than 500 MHz regardless of the fractional bandwidth. An initial NETEX UWB study was conducted during fiscal years 2002-2003. The objective of this initial study was to obtain an understanding of the electromagnetic interference (EMI) effects of UWB system operation on existing narrow band spectrum users and determine how they could be implemented in a manner that makes best use of their unique capabilities. The initial study encompassed: 1) measuring the effects of ultra wideband system operation on existing military spectrum users and defining UWB system parameters for coexistence, 2) modeling the impact of UWB transmissions on narrowband receivers and providing a set of tools for analyzing the UWB interaction with legacy systems, and 3) developing UWB propagation and channel models. This phase of the NETEX Program will consist of three sub phases: PHASE II, 1: Develop UWB Systems: PHASE II, 1 will last 18 months and focus on the development of power efficient UWB communication systems that can coexist with legacy systems and intentional jammers. The UWB waveform for PHASE II, 1 will be implemented in the design space identified by the Spectral Mask that resulted from the work that was performed during the initial NETEX study. The major development efforts required for PHASE II, 1 are improved detection, modulation, coding, interference excision techniques, simultaneous multi-function (comm., radar, timing and location), and an order of magnitude reduction in size and power. UWB systems developed should achieve at least 10-3 uncorrected bit-error rate (BER) with multiple (minimum of three) in band interferers located within 20 meters distance from the UWB system. The interferers should have modulation, bandwidth and effective radiated power that are representative of legacy systems operating in the band of interest, and they should not cause harmful interference to the UWB system and vice-versa when all systems are operating. PHASE II, 2: Develop UWB Network and Medium Access Control (MAC) Layers: PHASE II, 2 will last 18 months and will focus on the development of algorithms, protocols and distributed control for robust, scalable ad-hoc networking that effectively shares the UWB channel among non-cooperating UWB systems. The result shall be a power efficient, precision time based ad-hoc network that is capable of self organization and robustness using software adaptation. The network will also provide modular design and open interfaces for ?inter-stack? awareness and will provide a capability of simultaneous timing, location, ranging and communications. This will enable a new allocation of functions and different control of the network than is currently seen with the standard OSI model. The networking capabilities should be demonstrated for a multi-node UWB mobile ad-hoc network and it should be extensible to more than 10,000 nodes in an area that is 1 km2. PHASE II, 3: Demonstrate UWB Systems: PHASE II, 3 will last 24 months and consist of integration of systems designs and will include a series of experiments and demonstrations. The intent of these experiments is to demonstrate the military utility of UWB sensor and communications networks.
