MOBILE DEVICE USABILITY: TOWA

Published In: INTERNATIONAL CONFERENCE ON ADVANCES IN COMPUTING, COMMUNICATION AND INFORMATION TECHNOLOGY
Author(s): AHMED S. ALAWAJI

Abstract: The increasing trend of using smartphones and mobile applications led to more competition among smartphone manufacturers and companies to attract mobile customers. Mobile users use phones to perform all types of tasks ranging from home and work related tasks to phone calls. Due to the cost and time needed to launch a new mobile application product, a lot of companies neglect the use of comprehensive usability testing method to gather the users’ feedback before introducing the new product. In fact, mobile application products should be tested by real users to discover usability problems before the application is launched into market. A novel usability testing method for mobile devices has been proposed in this work to gather more accurate feedback from the users throughout the testing phase. The proposed method combines think-aloud protocol and field study to identify usability problems while gathering the users’ feedback. The results show a comprehensive analysis of the testing method

Abstract: VANET is a Vehicular Ad hoc Network; it is a new network technology where the cars are used as mobile nodes to form a communication network. In VANET, routing protocols have a significant role in terms of the performance because they determine the way of sending and receiving packets between mobile nodes. In this paper, we examine and analyze the performance of Ad-hoc On-Demand (AODV), Dynamic Source Routing (DSR) and Destination-Sequenced Distance Vector (DSDV) routing in terms of Packet Delivery Ratio, Average End to End Delay, Latency and Throughput. The objective of this study is to find the best routing protocol over all circumstances. Based on our validated results, AODV performs the best among all evaluated protocols.
