Abstract
The overall objective of the proposed Phase II effort is the development and evaluation of the OX-MAC (Optimized NeXt Generation MAC) suite of protocols to provide optimal media access control for mobile wireless networks formed by devices capable of dynamic spectrum allocation. OX-MAC is composed of XM-OptimalKernel, which disseminates transmission opportunities across the network, and XM-OptimalAccess, which allocates these opportunities on an optimal fashion. Scheduling algorithms in XM-OptimalAccess will be developed on the basis of Stochastic Optimal Control and Graph Theoretic techniques. Phase I has demonstrated the utility of these techniques for designing schedulers for CDMA2000 high-data rate systems. Specifically, in Phase I we designed a scheduler taking into account dynamic spectrum allocation, and demonstrated substantial increase in performance relative to current systems. Phase II will utilize these tools for designing OX-MAC for three classes of networks: (1) cellular type networks with a single base station, (2) cellular type networks with multiple base stations, and (3) Mobile Ad-Hoc Networks. OX-MAC will be coded and evaluated using high-fidelity OPNET platforms. BBN Technologies, a key contractor on DARPA's Next Generation Communications program, will provide unique expertise in dynamic spectrum allocation, as well as software modules to support the implementation and evaluation of OX-MAC. BBN will also provide commercialization support. Prof. Harold Kushner from Brown University and Prof. Sanjoy Mitter from MIT will be consultants in Stochastic Optimal Control, Queuing Theory, and Information Theory.
