“…In this simulation, more attention towards the session rejection due to unavailable resources as handover failure factor is considered. Therefore, we compare our proposed algorithm performance with previous works found in the literature [34,35] (e.g., [2,7]) which are content only with selecting one RAT for the checking resources.…”

“…We have different RATs in this scenario: UMTS covers whole analysis area as well as WiMAX(1) and WiMAX (2) partly overlay the service area. While MU is currently connected to UMTS and downloading files, he has started moving toward the WiMAX hotspots area.…”

“…Therefore, the number of users of mobile communication networks has increased rapidly as an example; it has been reported that "today, there are billions of mobile phone subscribers, close to five billion people with access to television and tens of millions of new internet users every year" [1] and there is a growing demand for services over broadband wireless networks due to diversity of services which can't be provided with a single wireless network anywhere anytime [2][3][4][5][6][7]. This fact means that heterogeneous environment of wireless systems such as Wireless Fidelity (Wi-Fi), Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications System (UMTS) and Long Term Evolution (LTE) will coexist providing Mobile Users (MUs) with roaming capability across different networks.…”

One challenge of wireless networks integration is to provide ubiquitous wireless access abilities and seamless handover for mobile communication devices between different types of technologies (3GPP and non-3GPP) such as Wireless Fidelity (Wi-Fi), Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications System (UMTS) and Long Term Evolution (LTE). This challenge is critical as Mobile Users (MUs) are becoming increasingly demanding for improved services regardless of the technological complexities associated with them. To fulfill these requirements for seamless Vertical Handover (VHO) two main interworking frameworks were proposed by IEEE Group and 3GPP for integration between the aforementioned technologies; namely, Media Independent Handover IEEE 802.21 (MIH) and IP Multimedia Subsystem (IMS), where each of them requires mobility management protocol to complement its work such as Mobile IP (MIP) and Session Initiation Protocol (SIP), respectively. In this paper, we overview these frameworks and show their components, benefits and drawbacks. Then we present our Imperative Alternative MIH for Vertical Handover (I AM 4 VHO) algorithm based on MIH framework and using fuzzy logic to provide low connection failure (probability of session rejection) and low signaling cost for enhancing VHO in heterogeneous wireless networks environment. Simulation based performance evaluation shows that the proposed algorithm reduces the probability of VHO connection failure by up to 75%.

“…There are number of MIH based Vertical Handover (VHO) approaches proposed in the literature. Some of them are based on Mobile IP version 4 (MIPv4) [19,20,21] and some are on MIPv6 [22,23,24]. Most of the work in MIH for VHO decision utilise RSS as the most important factor in their handover decision making process.…”

Many existing handover mechanisms trigger network selection based on dynamic performance characteristics such as Received Signal Strength (RSS), Delay, and Loss. These approaches do not take into account how the predictability of end user movement can be used to influence and optimize handover selection. Scenarios in which predictable movement can be observed include motorways, public service vehicles and student class schedules in educational institutions. This work investigates if the consideration of predictability of movement, with dynamic performance characteristics, could improve handover decision management. A range of relative weightings of dynamic performance and mobility predictability are evaluated. Results presented illustrate that taking predictable movement as an input metric has a significant beneficial effect on the handover decision process.
