Abstract
An important issue in heterogeneous wireless networks is how to optimally utilize various radio resources. While many methods have been proposed for managing radio resources in each network, these methods are not suitable for heterogeneous wireless networks. In this study, a new management method is proposed which provides acceptable service quality and roaming rate, reduces the cost of the service, and utilizes big data technology for its operation. In our proposed scheme, by considering various parameters such as the type of the service, the information related to the location of the user, the movement direction of the user, the cost of the service, and a number of other statistical measures, the most suitable technology for radio access will be selected. It is expected that besides improving the decision making accuracy in selecting the radio access technology and the balanced distribution of network resources, the proposed method provides lower roaming and lower probability of stopping roaming requests entering the network. By considering the various service classes and various quality of service requirements regarding delay, vibration and so on, this can be useful in optimal implementation of heterogeneous wireless networks.
Highlights
Now-a-days, various technologies with various goals are proposed for wireless access
Local wireless networks using the IEEE 802.11 standard, wireless urban networks using IEEE 802.16 standard, and cellular mobile networks (4G); considering that these networks vary based on bandwidth, the type of access to media, and the security they provide for the users [1], [2]
While usually the high bandwidth of local wireless networks such as 802.11 is very important for data transmission, due to the small coverage area, these networks are only available in hotspots such as hotels and libraries, forcing the moving user to return to the mobile network
Summary
Now-a-days, various technologies with various goals are proposed for wireless access. Selecting the best network must be based on policy, priority, and the sensitivity of these criteria as well as the effects it has on more general goals such as the load distribution. Another issue in heterogeneous wireless networks www.ijacsa.thesai.org (IJACSA) International Journal of Advanced Computer Science and Applications, Vol 8, No 11, 2017 is the nature of distributed access. In heterogeneous networks where even selecting the various access technologies of the network is up to the users, we have to meet the general goals of the network such as balanced load or optimized service, meaning that we are faced with a distributed optimization problem.
