Growing demands for pervasive and ubiquitous services over wireless mobile networks and evolution of such networks towards heterogeneous solutions have emphasized the necessity of more intelligent handoff decisions. The existing handoff management methods in the literature are mostly using signal strength measurements and other link quality evaluations not addressing the knowledge about context of mobile devices, users and networks. Recently, context‐aware handoff management has been considered as a novel candidate for fourth generation (4G) wireless technology. In this paper, user perceived quality of service has been considered in addition to traditional contexts such as user preferences, application requirements, network parameters and link quality for decision making. User perceived quality (UPQ) has been employed as a trigger source, in addition to link layer triggers which are emerged using media independent handover (MIH) event service. This paper presents a policy based mechanism for handoff decision making where fuzzy petri nets (FPNs) have been utilized as its evaluation algorithm. A case study has been provided by simulations to show the usability and user level satisfaction. Simulation results show superior performance in terms of UPQ, jitter and packet delivery measures.

Wireless networks and mobile terminals are evolving towards being heterogeneous. In this environment, intelligent handover decision, beyond traditional ones that are based on only signal strength, is needed so that terminals can select the best option available from diverse networks and services as per user requirements. In the process, it would enable user applications to switch automatically between active interfaces that best suit them based on application requirements and interface capabilities and to use multiple radio interfaces simultaneously ensuring the optimum usage of the network resources available to the terminal. To fulfill the above requirements, this paper proposes the design and implementation of a context-aware vertical handover decision algorithm suitable for multimode mobile devices in heterogeneous networks based on the Analytic Hierarchy Process (AHP).

Abstract. The next generation wireless systems will consist of heterogeneous networks from cellular, Wi-Fi, WiMAX to other emerging access technologies. Vertical handoff occurs when a mobile terminal decides to switch between networks. One of the challenging problems during vertical handoff is the selection of an optimal network that maximizes end users satisfaction. This paper presents an intelligent vertical handoff decision algorithm that selects the target network based on the traffic class of the mobile user. The algorithm uses two modules, to estimate the handoff requirement and to select the optimal network. These modules utilize Fuzzy Logic and Genetic algorithm to make an intelligent vertical handoff decision.
