Hierarchy-based knapsack approach for network selection in HetNets

In order to realise the dynamic network environment of current day wherein the end-users are equipped with various smart mobile devices and technologies, it is necessary to incorporate mechanisms which yield high speed and less end-to-end delay with minimum transition loss. Appropriate selection of the target network will help to resolve the issue to a major extent. The information regarding the next point of attachment is provided by the network to assist the node in taking decisions about altering the base station to suit to the then network situation. In this paper, an intelligent approach is incorporated by ranking the networks available in proximity and ignoring the less compatible ones. This scenario is accomplished between Wi-Fi and WiMax networks by the proposed hierarchical knapsack approach with dynamic programming, helps identifying the optimal scenario to support end-users while selecting a network for the handoff.
