A QoS based network selection scheme for 4G systems with preplanner for emergency services

Wireless communication encapsulates the earth into a global village with its reach to every nook and corner of the globe. The fourth generation (4G systems) of wireless communication was expected to be up for grabs from 2010s. However, due to the complicated hardware required the evolution of technology into 4G has been sluggish. Since 4G services require the integration of all the existing communication services into a global standard, new advancements are required in technology to solve the issues in the path to progress. The main purpose of this paper is to find an effective solution for the network selection issue, which is one of the the primary obstacles in 4G communication systems. This paper discusses the Quality of Service (QoS) based network selection technique, which utilizes multiple performance parameters, with the proposal for introducing a preplanner module for emergency services. And also the paper tries to find out the effectiveness of the proposal from the results obtained through the simulation executed.
