| Popis: | Heterogeneous wireless networks are an important component of Next Generation Networks and represent one of the main solutions to deal with the increasing demand for wireless communications. Joint usage of the transmission resources available in different networks allows seamless connectivity even in special cases, like Intelligent Public Transport (ITS) applications. In order to efficiently exploit the transmission resources available in various wireless access networks the entity providing the connectivity, e.g. a Mobile Router (MR), must have knowledge about the Context Information (CI) which characterizes the entire networking environment. This paper proposes and analyzes several Load Balancing (LB) algorithms in heterogeneous networks which use only the local CI respectively the network level CI and shows that the algorithms using the network level CI have superior performance. The evaluation of the proposed algorithms was performed using the CI measured in a network composed of three 3G+ cellular networks. |
