Abstract

Smartphones and portable devices are widely used these days. Data transmission networks such as 3G and Wi-Fi are used for most smartphones, and LTE is quickly increasing its market share in order to support enormous network users who cause data congestion on every part of network topology. Especially, wireless part of network suffers from starvation and congestion due to many users who wish high quality Internet service such as HD video streaming. In this paper, we propose an efficient mechanism of auto-connecting qualified Wi-Fi network for the next generation smartphones in order to provide acceptable Internet service for device users. One of authentication-free access points and others that are provided by contracted Internet service provider can be automatically connected with the mechanism. Also, quality of experience (QoE) of the connected AP is guaranteed by estimating Signal to Interference and Noise Ratio (SINR) which is derived by the number of stations sharing the same channel. We implemented the proposed mechanism in both Android phone and also OPNET simulation, and also we conducted a performance evaluation study. The simulation results indicate that the proposed mechanism retains the best set of candidate APs to be connected and improves the MAC layer throughput.
