Engineering and the Physics Department on a Smart Grid project. He has also been collaborating with colleagues in other countries most notably with a former MSc student who is working on her PhD in Korea. One of his main objectives is to reach out to indus- try in order to be able to collaborate with them and have his students work on practical problems in industry. One such collaboration is with the Trinidad and Tobago Electricity Commis- sion. Professor Hosein has distinguished himself as a true innovator mainly through the many patents granted in various disciplines Telecommunications Wireless Communications and Mathemat- ics and in various research stages within these industries Products Standards and Advanced Research. Each of these patents has the potential to generate tens of millions of dollars in revenue.Here are brief descriptions of some of these patents. System and Method for Synchronized and Coordinated Beam Switching and Scheduling in a Wireless Communications System This work was performed during the standardization of the 4G cellular standard and proposed as a future enhance- ment. This together with some related alternatives is now being considered for incorporation into the 5G standard and hence will lead to significant royalties for my previous employerHuawei. System and Method for Utility-Based Scheduling for Space Division Multiple Access SDMA on an Uplink of a Wireless Communications Network In 5G cellular networks multiple users will be served over resources traditionally used for a single user. The work in this patent was carried out to determine how such simultaneous users should be chosen and served. System and Method for Scheduling Variable Bit Rate VBR Streams in a Wireless Communications System In addition to traditional cellular service modern cellular networks can use broadcast mechanisms for distribution of content such as live sports feeds.One difficult problem is how should these feeds be multiplexed. The algorithm proposed in this patent increases packing efficiency and saves on device energy usage. This patent also has the potential for significant royalties. System and method for wireless network congestion control Congestion control in new cellular networks is difficult because of the wide variation in the resources required for data connections as opposed to voice connections. In this patent a truly novel approach is proposed and this work has since led to research on pricing for Quality of Service QoS offerings. System for supporting consecutive and distributed subcarrier channels in OFDMA networks This is some groundbreaking work in optimization that received a best paper award at the 2006 IEEE WPMC conference. System and method for wireless network admission control based on quality of service This again is early work i.e.before cellular networks had the infrastructure to deploy such techniques that was encouraged by his employer.It contains a novel approach for admission control that takes into account QoS constraints. Dynamic control of multiple heterogeneous traffic sources using a closed-loop feedback algorithm This is an example of work done while working in the telecommunications field at ATT Labs.It is a new technique for traffic control. Method and apparatus for synchronizing the provision of data among geographically distributed databases In the early nineties when Local Network Portability standardization was being developed this work addressed an extremely important problem that of synchronization of the associated databases. Local Number Portability is soon to be introduced in Trinidad and Tobago. Selected Publications P.
