“…Wu et al 21 analyze the delay observed in vertical handoff in wireless local area network integrated with universal mobile telecommunications system (WLAN‐UMTS) when session initiation protocol (SIP) is used. Azhari et al 22 highlight the use of vertical handoff support node (VHSN) to improve performance and quickly reroute media flow via a local BS. The selection of optimal target network is done by Chang and Chen 18 in a two‐phase approach that includes RSS prediction and MDP analysis.…”

Summary Vertical handoff is a major concern in the operation of mobile connections. Multiple wireless networks collate to provide smooth and quality service to the users over mobile connections. This paper formulates a Markov decision process for handoff decisions with a sample space that includes a union of parameters that are important for making a handoff decision. The major contribution of this paper is to propose three different yet closely related algorithms for reducing the computational complexity of the original problem. In particular, we propose a feature‐wise assessment algorithm, a network‐wise assessment algorithm, and a hybrid approach for computational complexity reduction. Discussed algorithms give pseudo‐optimal solutions with a significant reduction in computational complexity. Results indicate that different complexity reduction algorithms perform best under different circumstances. This provides a guideline for the selection of complexity reduction algorithms based on real scenarios.

“…For example, a UMTS subscriber can reuse its subscriber identity module (SIM) or user service identity module (USIM) for WLAN services [19]. Owing to such flexibility, the loosely coupled approach has attracted the most research and application attention at the initial stage of heterogeneous wireless networks [20,21]. However, this approach is relatively inefficient because of its long signaling path and redundant processing during roaming process as well as a large number of network elements involved in management operations.…”
