A Novel Mechanism on Network Selection for Fourth Generation Communication Networks

Abstract

In a heterogeneous networking environment of Fourth Generation communication technology, there will have a coexistence of different radio access technologies to serve the user. The users will always try to get the best service from the heterogeneous network. So selection of best access network at a particular time will be problematic and challenging. There will be a conflict between the network technologies of a heterogeneous networking system. We have taken into account the influence of some factors on which the selection of best access network will depend. Also, we have tried to solve the network selection problem by using Game theoretical concept. By using the concept of strategy space, quality points and weighting factors in the game theoretical model, a mathematical way for selecting the best network is demonstrated. The paper introduces the concept of optimum network selection mechanism from any number of competing networks. Lastly it is shown that the best connected networking system can always be possible in 4G communication network using this network selection mechanism efficiently.
