“…A similar scheme was proposed to enhance the QoS of a network through the optimization of different handoff parameters such as data rate and handoff latency [1], and the decision for handoff was performed using a hybrid of fuzzy logic and analytic hierarchy approaches. A hierarchal scheme for discovering network selection rule based on media independent handoff (MIH) optimization has been proposed in [13]. In their experiment, a number of APs/BSs in a particular zone were connected to a zone media independent information system (MIIS) server attached to both the local and global MIIS servers.…”

Optimizing the balance between different handover parameters for network selection is one of the challenging tasks for seamless communication in heterogeneous networks. Traditional approaches for network selection are mostly based on the Receive Signal Strength (RSS) from the Point of Attachment (PoA) of a network. Most of these schemes are suffered from high handover delay, false handover indications, and inappropriate network selection for handover. To address these problems, we present an optimized network selection scheme based on the speed of a mobile node. A mechanism based on two different thresholds on the speed of a Mobile Node (MN) is integrated in the proposed scheme. If the speed of an MN is greater than any of the threshold, the MN performs handover to a particular network. We employ Grey Relational Analysis (GRA) in the proposed scheme to select the best PoA of the selected network. Similarly, to deal with false handover indications, we proposed an optimized handover triggering technique. We compare our proposed scheme with existing schemes in context of energy consumption for scanning, frequent and failed handovers, packet loss ratio, and handover delay. The proposed scheme shows superior performance and it outperforms existing schemes used for similar purpose. Moreover, simulation results show the accuracy and performance of the proposed scheme.

“…As the networks are growing rapidly, load on a single MIIS server is increased. This problem is identified in [19] with a solution of dividing the network in different mobility zones. Each mobility zone is connected with a zone MIIS server which is further connected to a local MIIS server.…”

Uninterrupted internet services are need of the day and their demand will increase in future by manifold. However, providing uninterrupted services under heterogeneous networks environment is a challenging task. One of the major challenges in this regard is the management of handover system between various networks. This paper proposes a handover management scheme by dividing the total coverage area of the base station (BS) or access point (AP) into three different zones (strong, average, and weak zones), respectively, on the basis of receive signal strength indication (RSSI) to provide fast vertical handover support in heterogeneous wireless networks. Furthermore, a new event is proposed and added to the IEEE 802.21: media independent handover (MIH) standard to integrate the functionality of multithreshold. The proposed scheme is implemented in NS2 and it is shown that our scheme provides a superior performance over the previous methods used for similar purposes.
