چکیده
— Dynamic virtual machine migration is a key technique technology in the cloud computing, an algorithm is proposed in this thesis, which is a dynamic resource scheduling based on minimum load imbalancing measurement. First of all, load balancer in scheduler judges the overload phenomenon; we need to migrate VM (Virtual Machine) on physical machine. Then, according to the records in load balancer, we calculate the load imbalancing measurement of the other entire working PM (physical machine) relative to the overload host. Choose the PM which has the minimum load imbalancing measurement as candidate host. Simulation results indentify this algorithm is able to realize efficient load balancing, acquire an optimal resource utilization of cloud computing system and maintain a low level of load imbalancing.

Dynamic Channel Allocation in Interference-Limited Cellular Systems with Uneven Traffic Distribution
Most recently proposed wireless dynamic channel allocation methods have used carrier-to-interference (C/I) information to increase the system performance. Power control is viewed as essential for interference-limited systems. However, the performance of such systems under an imbalance of load among cells, as may occur often in microcells, is largely unknown. Here, we study a typical interferenc...
