Gestión de Carga en Sistemas de multi-acceso inalámbrico

Abstract

Currently, wireless communication systems have a limited amount of radio resources (e.g. bandwidth, transmission power, etc.), in this order, it is important to define mechanisms to use these resources efficiently to maintain quality in the operation of system. Given the above, in this paper a mechanism for load management is presented using the probabilistic technique simulated annealing (SA), this mechanism is based on the solution provided by an analysis of levels of received signals and assigning costs based on different technologies study that are performed for each of multiple wireless access available to a mobile device. This work focuses on the development of a load balancing algorithm that allows managing your multiple access systems in order to maintain high data rates and provide a good quality of service despite bandwidth limitations and adverse conditions characterizing the propagation channel radio. In summary, the main objective of this work is to obtain a set of operational access or access to a level of load balancing, which minimizes the total cost of operation of the system subject to maintaining the channel capacity above a certain threshold.
