“…Maaloul and al. [9] have presented a novel context aware vertical handover algorithm based on multiple attribute decision making and the results have shown that algorithm avoids unnecessary triggered handover. However, from the above cited works none of the existing approaches take the application-specific QoE parameters into consideration while taking handover decisions.…”

Different wireless technologies are assumed to cooperate in a single heterogeneous environment in future network deployment schemes. Such environment is characterized by a multitude of new services based on multimedia services like gaming and real time video streaming. When dealing with video services, traditional QoS solutions are not sufficient for ensuring video awareness and good user's perception. Quality of Experience (QoE) management approach have been introduced to estimate the quality level of multimedia services. In an heterogeneous environment every user can switch between many networks during his communication in a vertical handover (VHO) process and QoS may decrease as well as the video quality. That is why, maintaining the requested QoS and keeping a satisfying QoE during a VHO process is the main goal for HWNs.In this paper, we proposes a QoE-fuzzy vertical handover algorithm with QoS management and QoE decision. Simulation results of the proposed system show performances improvement for throughput and delays.

The 4G Wireless Networks (WN) have not only provided seamless connection; they also strive to provide Quality of Service (QoS) to the users. However, providing efficient QoS to the users is quite often challenging due to large number of users and significant traffic load. One of the popular techniques to provide consistent QoS to the user is Vertical Handoff (VH). The main concept of VH is to migrate the user to another WN which can provide the requested QoS. Even though substantial contribution has been made in the literature for VH techniques, security oriented VH techniques are limited in number. Security aspect has become critical in Next Generation WN, due to new form of threats which are being introduced, and VH techniques also need to focus on security issues to provide safe and robust communication. In the literature, survey on different security threats, secure VH techniques and future issues has not been effectively presented; in this work, comprehensive survey on all these aspects is presented to aid future research in secure VH

Transferring a huge amount of data between different network locations over the network links depends on the network’s traffic capacity and data rate. 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 an 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 vertical handover decision algorithms: equal priority, mobile priority and network priority. The simulation results illustrate that the three types of decision algorithms outperform 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 the equal priority and the mobile priority handover decision algorithm. Finally, the simulation results are validated by the analytical model.
