Diseño y programación de un algoritmo para movilidad de usuarios en redes heterogéneas

Abstract

Abstract:During the last years wireless technology has evolved offering better quality and coverage. One way to provide mobile service is through heterogeneous networks, where macrocells and several base stations of smaller size and range are involved. Being a network mobile, users roam the network and the assigned base station changes depending on of the environment. During the change of base station, a series of parameters must be met that guarantee good service. In the present titling work an algorithm is presented of handover using parameters such as the direction and speed of the user, among others, the which move randomly using a mobility model. The results obtained reflect performance improvements in the network of 12% in the sparse scenario, 38% in the dense and 50% in the very dense when the handover algorithm is used, based on the direction and speed of the user in conjunction with a mobility model, achieving a more efficient classification when selecting a possible base station to which you will connect.
