Transferring a huge amount of data between different network locations over the network links depends on the heterogeneous wireless network. Such a network consists of several networks with different access technologies. Traditionally, a mobile device may be moved to achieve the operations of vertical handover, considering only one criterion, that is, the received signal strength (RSS). The use of a single criterion may cause service interruption, an unbalanced network load, and an inefficient vertical handover. In this paper, we propose enhanced vertical handover decision algorithm based on multiple criteria in the heterogeneous wireless network. The algorithm consists of three technology interfaces: Long-Term Evolution (LTE), Worldwide interoperability for Microwave Access (WiMAX), and Wireless Local Area Network (WLAN). It also employs three types of the vertical handover decision algorithms: equal priority, mobile priority, and network priority.The simulation results illustrate that the proposed handover decision algorithm outperforms the traditional network decision algorithm in terms of handover number probability and the handover failure probability. In addition, it is noticed that the network priority handover decision algorithm produces better results compared to equal priority and mobile priority handover decision algorithm. Finally, the simulation results are validated by the analytical model.

“…By far, the schemes in [91,101,102] are closer to our design where parallel FLCs are used in conjunction with AHP or TOPSIS to produce the final ranking of available networks. The major deficiencies with these schemes are the lack of utilization of all QoS related parameters to perform network selection decisions.…”

Next generation wireless networks consist of many heterogeneous access technologies that should support various service types with different quality of service (QoS) constraints, as well as user, requirements and provider policies. Therefore, the need for network selection mechanisms that consider multiple factors must be addressed. In this paper, a network selection method is proposed by applying the analytic network process to estimate the weights of the selection criteria, as well as a fuzzy version of technique for order preference by similarity to ideal solution to perform the ranking of network alternatives. The method is applied to a heterogeneous network environment providing different QoS classes and policy characteristics. Each user applies the method to select the most appropriate network, which satisfies his or her requirements in respect of his or her service-level agreement (SLA). Performance evaluation shows that when the user requests only one service, the proposed method performs better compared to the original technique for order preference by similarity to ideal solution, as well as the Fuzzy AHP-ELECTRE method. Moreover, the proposed method can be applied in cases where a user requires multiple services simultaneously on a device. The sensitivity analysis of the proposed method shows that it can be properly adjusted to conform to network environment changes.of heterogeneous networks, seamless interworking among the different technologies is also needed [7]. Thus, special attention to the VHO process should be given [8].The VHO procedure consists of three main steps including the handover initiation, the network selection, and the handover execution. The initiation step contains the required procedures to identify the available access networks and select the time of handover in respect of network conditions and user mobility. The network selection step is related to the selection of the most appropriate network alternative based on the available network characteristics, user preferences, and applications requirements. Finally, the execution step completes the handover process by seamlessly connecting the terminal to the selected network. This paper deals with the network selection step of the VHO process.Existing handover network selection schemes employ multi attribute decision-making methods (MADM), fuzzy logic, neural networks, and utility functions [9]. However, because the selection of an access network depends on several parameters with different relative importance, the access network selection problem is usually looked at from the aspect of multi-criteria analysis and more specifically by applying different MADM algorithms. In this paper, a network selection method is proposed by employing two MADM algorithms: the analytic network process (ANP), which is an extension of the analytic hierarchy process (AHP) for criteria weights calculation, and a fuzzy version of the technique for order preference by similarity to ideal solution (TOPSIS) for accomplishing the ranking of the candidate net...
