Enhancing the quality of service of mobile-based software over Wi-Fi direct

Abstract

Mobile-based software has become popular in the software industry. In light of this, people are now relying on using various mobile software applications to do their daily tasks. Smartphones can form a group and connect, off the Internet, using Wi-Fi Direct (WFD) to share data and utilize services. The lifetime of the applications that are over WFD is depending on the proper selection of the group owner (GO). If a group owner becomes dysfunctional, the quality of service (QoS) of these software applications will be compromised due to the loss of information, the time wasted repairing the group, and the exhaustion of resources. Therefore, plenty of research has been conducted on how to choose group owners to enhance the software and application quality. This research provides a software methodology to enhance QoS in terms of dependability and by extension reliability and repairability of software over WFD technology as well as the rationalization of resources used to perform services. We provide an efficient mechanism to choose the GO and the backup device based on the software service that the device can provide and different effective parameters like remaining battery power, Received signal strength (RSSI), and signal-to-noise ratio (SNR). Besides a new technique to reform the group seamlessly to make group self-recoverable. A methodology has been implemented and tested on the real testbed using Android smartphones and proven to improve the time of reformation by approximately 80 % and result in a semi-continuous connection even if the group is broken.
