These results prove the control-system stability and the comparative suitability of classic controllers to keep the multimedia-system consumption close to the desired value in steady state with settling times as short as a single sample interval. Resource allocation and power optimization is a new challenge in multimedia services in cellular communication systems. He is a founder of the Network Control Research activity with extensive international academic and industrial collaborations. Transition probability matrix 81 3. State 1 to state 1, state 1 to state 2 and state 1 to state 3 61 2. Channel quality indicator 8 1.

Three-state fixed model 47 2. The benefit of closed-loop power control is the higher homogeneity in terms of throughput across the entire network area and the ability to automatically stabilize the network performance under different conditions like cell load and traffic distribution. A comprehensive analysis is performed to study the specified sleep mode with generalized traffic processes. State 2 to state 1, state 2 to state 2 and state 2 to state 3 61 2. Sleep states H2 and H3 51 2. Simulation results in a fully loaded network show high throughput for open-loop fractional power control for the user located in the vicinity of the serving eNodeB, however, steep performance degradation has been observed when the user is moving towards the cell edge. Sleep states H2 and H3 51 2.

Performance is measured in terms of both average cell throughput and cell edge user throughput. Transition probability matrix 50 2. The numerical result indicates that the new policy can significantly reduce power consumption. This paper presents a dynamic spectrum sharing algorithm to minimize the inter-cell interference, so as to achieve a high system performance. A comprehensive system level simulation model has been used with a facility to trace a particular test user during its motion from eNodeB towards the cell border and back to its initial position. However, these data-heavy applications require lots of battery power on the user equipment. Energy consumption by wireless communication systems is a vital concern in the present world, not merely to reduce energy consumption but also to mitigate environmental degradation due to effluence caused by extreme energy consumption.
