A novel approach for optimal network selection in heterogeneous wireless networks

Today Communication industry concentrates more on the live information transfer without altering the existing infrastructure and hence requires a single convergence platform of all networks´ access. The next generation systems support multimode, multi-access and reconfigurable devices to support inter-working of heterogeneous networks. The network selection is user-centric and based on multiple QOS (Quality of Service) parameters like bandwidth, cost, security level, call drop probability etc., to select appropriate networks. The proposed algorithm uses a distance function to generate an ordered list of various access technologies called networks in a particular region according to multiple user preferences and level of interest. Further level of customization is done with user preference in terms of giving priority to few parameters and is implemented by weighted distance function.
