| description | VHOs (Vertical Handovers) have become popular research problems in real-world environments, with frequencies of access to the network increasing to millions of users. It is required to select and provide the most suitable access network for the users who enter into the network environment. This work introduces a combination of techniques namely M-ANPs (Multiple Analytic Network Processes) combined with TOPSISs (Method for Order Preference by a resemblance to ideal solutions) for choosing access networks that satisfy QoS's (Quality of Services). Generally, networks fail to ensure the successful routing between different access networks which is handled by this research work with its proposed QoS-VHP (QoS-aware vertical Handover Process). In this work initially, handover initiation is performed. After initiation, system discovery is performed to identify the nearest access network which can be reachable with minimum distance and bandwidth consumption. After picking the nearest access network services, a handover decision is achieved to select the most suitable access network which can satisfy the constraints CB's (Costs for Bytes), ABs (Available Bandwidths), Security, D (Packet Delays), J (Packet Jitters) and L (Packet Losses). This optimal selection of access networks is used to Modified TOPSIS Method to ensure a more accurate selection of suitable access networks for reliable data transmission. After the handover decision process, handover execution is performed with the concern of the transport layer which is done by using a modified Stream Control Transmission Protocol. The overall proposal was simulated on an NS2-simulator where the expected parameters like handover delay, probability of handover failure, and throughput are evaluated with the results of 0.69–0.77 s, 0.45, and 80Kbps respectively which, proved its ability to optimize protocols. |
