Abstract:
The network selection process has been widely studied in recent years as a result of technological evolutions which has been presented to the user with ease of access involving issues related to mobility and ubiquity of access to data. Thus, several proposals have already been presented, always showing a lot of variables that need to be considered for a good selection. However, these solutions presents a computational cost that grows with the complexity of the technique used, the number of variables involved and the ways of collecting these variables. The most common solutions, and still used in smart-phones and tablets, are those based on the signal level measured at the interface of the mobile, due there is no incremental computing cost to devices, maintaining these solutions as feasible. Therefore, this paper proposes a new metrics based on a mapping between the variables of network QoS (delay, jitter and packet loss) and the signal level, presenting, through experimental tests, prediction equations these variables based only on signal level measured at the device interface. The validation of the metrics is presented using a simple network selection algorithm, operating in an environment with two independent and overlapped WLANs and no distribution system, comparing the results obtained with the proposed metric and WLAN-First algorithm, present in most of smart-phones and tablets today.
