“…In such a scenario, no user should connect to SP 2 as SP 3 offers better utility at a cheaper or equal price (11). Hence, substituting s 2 = 0 in (20), (24), (28), and (30), within the coverage area of SP 3 and not in (18), (22), and (26) as they are beyond the coverage of SP 3, we obtain q 03 = q 13 = q 23 = q 33 = q 43 = 0.…”

“…In the presence of heterogeneous wireless networks, multiple path selection, i.e., multi-homing, based on QoS requirements and available signal-to-interference-plusnoise ratio (SINR) is proposed in [17]. In [18], a network selection algorithm, based on fuzzy MADM, in the presence of heterogeneous wireless networks is presented. A multi-criteria based vertical handover (HO) algorithm in the presence of heterogeneous networks is proposed in [19].…”

“…Thus, the probabilistic framework proposed in Section IV is an effective way to model the average (steady state) users' network selection behavior. Hence, an additional term of s 2 is present in (18) to include the effect of utility and price on the users' network selection behavior. Beyond the WLAN coverage, only SP 0 and SP 2 are available.…”

In the presence of heterogeneous service provider (SP) networks such as wireless local area networks and cellular networks, users have to make a choice. The quality of service provided and the price charged by an SP play a crucial role in this decision process. In this paper, we study the network selection behavior of mobile users. A novel probabilistic framework is presented, with explicit analytical expressions for the transition and steady state network selection probabilities of the users. The proposed framework utilizes the price charged and the utility obtained at the SPs in obtaining the transition probabilities, even in the presence of multi-homing users. Furthermore, network-level parameters such as call blocking probabilities and throughput are obtained in terms of the steady state probabilities. Numerical results indicate that the prices and utilities at the heterogeneous SPs have considerable impact on the overall network performance.Index Terms-Cellular network, heterogeneous networks, transition probability, wireless local area network (WLAN).

“…This fact made Wi‐Fi selection as an important criteria to be concerned in the research of vertical handover system. are the works that proposed several vertical handover systems that contain various wireless link quality metrics for the selection of a qualified AP. However, all these work only propose the definition of their metrics and the way to derive the corresponding variables without any justifications or in depth research on usability and applicability.…”

Due to increasing demand of wireless services for portable devices, numerous efforts to enhance wireless network performance have been made for decades. Many researchers were focused on the word ‘seamless’ for sustaining connectivity during a handover process, but wireless performance of destined access point (AP) is rarely considered. This paper analyses thoroughly usual network connection behaviour, captures several problems from the procedure, and proposes interference‐avoiding selection (IAS) mechanism that associates a wireless AP, which is expected to perform better than other APs nearby. Proposed selection mechanism concentrates on utilization of each channel within one hop range and received signal strength measured by incoming beacons from surrounding APs. Possible interference by adjacent channels is also considered in this paper. Moreover, unlike any other prior selection mechanism, IAS protocol does not require any modification on existing communication protocols, extra delay to evaluate surrounding APs, and support from huge data server that collects information and derives quality of surrounding APs ahead of the selection phase. Various analysis and performance evaluations are progressed using OPNET, ns2, and Android programming, and the evaluation results showed that proposed selection mechanism can increase the throughput of original selection mechanism by more than 55% in average.
