In the following years, it is anticipated that users will expect wireless networks to provide a performance similar to today's wired networks. Future ubiquitous wireless networks will therefore need to offer more reliability, higher accessibility, larger bandwidth and more support to a wide array of applications than they are today. Several physical layer transmission technologies such as cooperative communications and antennas with dynamically reconfigurable radiation patterns have been developed in recent years to address these issues and improve the reliability and throughput of wireless links. We can expect that the aforementioned technologies will be commercially deployed in 10 to 15 years. The transmission technologies considered in this research program introduce new paradigms such as having multiple nodes cooperating for establishing one communication link or nodes with time-varying coverage or interference zones. Complex interactions are therefore induced in the shared wireless medium and between users. Research aimed at efficiently integrating cooperation and reconfigurable antennas in wireless systems is thus extremely important. This research project contributes to this effort by exploring new niches to develop groundbreaking approaches, particularly for the multiple access control layer, the radio link control layer, and the implementation and characterization of these systems. The current research activities in these areas are either absent or at the infancy stages. Our research projects will be at the forefront in this constantly growing sphere of activities and will therefore have a significant impact on the community. They also have the potential to influence the standardization process of future wireless networks integrating cooperative communications and dynamic radiation pattern diversity, and can generate intellectual property, which can translate into economic activities in the local industry through technology transfers. Finally, this project will contribute to the training of highly qualified personnel, with an in-depth theoretical and practical understanding of wireless communication systems, which will play a role in improving the competitiveness of the Canadian wireless industry.
