The study revealed that this method is found to achieve better performance and QoS support to users and greatly reduce the handover failures when compared to the traditional TOPSIS method. The paper reveals that WiMax is one of the technologies designed to meet the demands of the application and the results obtained show that the network conforms to ITU-T performance standards and can deliver integrated NGN services. In such a case, the ping-pong effect is high because the selection of the network is based on previous history stored in the mobile terminal. The simulation is repeated number of times and average value is taken to increase the accuracy of observed result. The cost factor is also added for choice of the network along with RTT to have reduced connection failure. Hotspot 2. Competing Interests: The authors have declared that no competing interests exist. Section 6 gives the current limitations of the proposed work and future direction.

    Since the proposed work is network controlled and the optimal solution on vertical handover has to be initiated to mobile nodes.

    Students and professionals new to the wireless field will also find this book to be a good foundation in network planning, performance analysis, and optimization. The third section of our study measures the end-to-end delay during handover initiation. There are few open issues that need to be further investigated for vertical decision making process.

    Nodes may fall out of the network for a variety of reasons, including insufficient battery. Optimizing network performance and utilization of network assets.
    Provides an end-to-end perspective, from network design to optimization Incorporates the hands-on experiences of numerous researchers Single authorship allows for strong coherency and accessibility Details the complete iteration cycle of radio link budgeting for coverage planning and dimensioning Rahnema demonstrates detailed formulation of radio capacity and coverage in UMTS, and discusses the tradeoffs involved.

    The proposed handoff decision strategy is designed for network-controlled handoff, which erratically removes the limitation of mobile-controlled handoff. The information provides the QoS of the other network, and the mobility management protocols enable the mobile to connect to the best network through of the operation of the proposed mechanism. The vertical handoff mechanisms are generally grouped in terms of mobile-controlled handoff and network-controlled handoff processes.

    In automatic performance optimization, the trade-off between cost and coverage has Some aspects of performance fall out of the scope of a static model; this applies to. Even though an improved network can provide good support for high-speed users.

    used as a self-optimizing mechanism for the automatic adjustment of network for WLAN, WiMax and UMTS network alternatives for simpler implementation. selection and overload conditions in the chosen network can cause fallout in.

    In a heterogeneous wireless network, handover techniques are designed to in the chosen network can cause fallout in the form of handover failure. in terms of the network performance measures such as throughput and delay. WLAN, WiMax and UMTS network alternatives for simpler implementation.
    However, the delay in handover process still exists.

    The simulation is repeated number of times and average value is taken to increase the accuracy of observed result. Literature also showed work carried for vertical handover adopted through WiMax by Nadine Akkari et al [ 21 ].

    Fig 2. The network initiates the handover at the correct time, and the network controller knows to which network the mobile node should be connected.

    Fact authentication schemes enable handover decision to distribute the context to the target candidate network which may improve the performance during handover process.

    Rahnema holds an M. First stage of the proposed work takes signal strength and network reliability to provide solution to unnecessary handover computations.

    However, bad network selection and overload conditions in the chosen network can cause fallout in the form of handover failure. Dynamic programming observes the principles of optimality that facilitates application to any complex problems. To enable ongoing communication activity, handover technology is designed to allow users to roam across networks.

    Consistent best-possible access to a network with widely varying network characteristics requires seamless mobility management techniques.
