For M2M (Machine-to-Machine) machines in cellular networks, employing high transmission rates or transmitting in large power actually cost them much energy. This is harmful to the machines, especially they are operated by batteries. The Relay Node (RN) in Long-Term Evolution-Advanced (LTE-A) networks is used to enhance the coverage of high data rate and(More)
Project Summary This project explores fundamental systems issues in query processing performance. We investigate this problem from three different directions: client-server processing, heterogeneous environments, and database compression. First, we devised new query processing strategies than push processing capabilities into the client, and we devised(More)
