Research Interests

I am currently involved in the following research areas: self-organizing networks, wireless mobile networks, high performance networks, mobile computing and databases, reliable and dynamically reconfigurable distributed systems, complex software development, parallel processing, and performance measurements and analysis. In self-organizing networks, I am developing new techniques and protocols that allow network nodes to form spontaneous networks, assemble the network themselves, dynamically adapt to device failure and degradation, manage movement of network nodes, and react to changes in task and network requirements. In wireless mobile networks, I am investigating adaptive communication protocols for large-scale mobile information systems and  the performance implications of these protocols.  In mobile databases and computing systems, new mobile transactions and client-server caching techniques are being developed and studied.  For  reliable and dynamically reconfigurable distributed systems , we utilized efficient system facilities and tools for  detecting dependencies and  maintaining global state consistency.   We developed a complex software development environment  that allows designers to develop large applications with complex interaction. It contain tools for  analysis of liveness,  dependencies,  reliability and runtime adaptation. These development environment and operating mechanisms  form the common framework for evolutionary distributed and parallel applications.
