We extend the problem of optimizing user association for load balancing in cellular networks along 2-dimensions. First, we consider joint transmission, which is one of the coordinated multipoint techniques with which a user may be simultaneously served by multiple base stations. Second, we account for, mathematically, the coupling relation between the base stations’ load levels that are dependent...
Heterogeneous networks (HetNets) have been considered as a promising technique for improving spectral efficiency, but the energy efficiency influenced by the fluctuation of user numbers should not be neglected to achieve green communications. We introduce the energy-efficient switch-off mode algorithm for pico cells to reduce power consumption in the self-organizing network (SON). Once the switch-off...
Self-Organizing Network (SON) is a key feature of the Long Term Evolution (LTE) system. SON introduces several Self-Optimizing features for the LTE's Evolved Universal Terrestrial Radio Access Network (EUTRAN), thereby improving performance, flexibility and lowering costs through network intelligence, automation and network management. Mobility Load Balancing (MLB) is one such feature that has recently...
In this paper a flow-based model balancing queues at the nodes of MPLS-network is proposed. The novelty of the model is that it, in the contrast to the previously known models takes into account the features of the Traffic Engineering Queues technology. This technology has a purpose to ensuring load balancing of the node buffer resource.
Recently, numerous job scheduling techniques have been proposed for improving the efficiency of resource sharing in heterogeneous computational grids. However, as we have noticed, some scheduling algorithms, especially those working in batch mode, are likely to be suffered from deficiencies when extended to an non-dedicated grid environment, where the consistency degree of underlying computing environment...
