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.

UMTS Network Planning, Optimization, and Inter-Operation with GSM is an accessible, one-stop reference to help engineers effectively reduce the time and costs involved in UMTS deployment and optimization. Rahnema includes detailed coverage from both a theoretical and practical.
GPRS is able to provide the user with a greater increase in data throughput, and. Once these three trade-offs have been optimized, an individual balance can be these frequency ranges that fall out of the agreed tolerance parameters.
This situation motivates the division of the network into zones, and computation of the ranking score by TOPSIS method offers a deviation of the decision variable towards the ideal solution.
Access point V i accepts a certain number of mobile nodes in the handover process. Moe Rahnema. The proposed TOPSIS KVD generates vertical handover decisions by taking into consideration of the significant metrics such as signal strength, RTT, reliability, cost and traffic handling priority of the candidate network.

However, it has become essential to offer an efficient handover mechanism to meet different QoS requirements and maximize the resource utilization of the network. This article has been cited by other articles in PMC.

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.

Therefore, such a design cannot select the best network for mobile devices because the device has limited power and limited information on the networks.

ComCom31 10 — The mobile nodes are assisted by the optimal knapsack problem formulation for handover initiation. 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.
Current Limitations and Future Research Direction There are few open issues that need to be further investigated for vertical decision making process. Added to Your Shopping Cart.
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.

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 ].
