This project deals with UWB-based ad hoc networks. The physical layer objective is the development of signal processing schemes to improve the performance (for both impulse radio and continuous-wave transmission techniques). The MAC layer considers asynchronous data transmission and structured/unstructured architectures. It will study broadcast/unicast performance, considering cross-layering optimizations. The objectives include the definition of an abstraction suitable for the network layer for supporting differentiated levels of quality of service, and its concrete implementation, supported on different resource reservation mechanisms. The network layer objectives include the analysis of the behavior of ad hoc routing algorithms and service location services, and their optimization introducing cross-layering tuning at the MAC and physical layer. An important objective is to take advantage of the complementary competences of the teams involved in the project, leading to relevant contributions to the specification UWB-based ad hoc networks and to stronger skills, in both teams.
