With the development of internet technologies and applications, video becomes the main source of online generated data. Real-time generated big data video on the internet have many challenges, which include broadcast, evaluation, storage, analysis, and transmission. For multimedia applications, processing and communication are important areas to realizing ambient intelligence and Quality of Service (QoS) is a major challenge for designing and implementation of processing and communication of multimedia traffic. In this study, simulation results have verified the possibility and effectiveness of the developed intelligent wireless QoS technology in terms of big data video communication over a Wireless Local Area Network (WLAN). Structural Similarity Index (SSIM) and Video Quality Metric (VQM) video quality matrixes are used for measurement of received video at receiver. The results show that dynamics frame aggregation mechanism improve the big data video delivery for SSIM and VQM in comparison to frame aggregation mechanism defined by the draft of IEEE802.11n WLAN.

Mobile communication systems are crucial for the ambient intelligence because the most of the sensors rely on mobile and wireless technologies and to collect, process and store the big data. Multimedia applications like big data video over Internet Protocol (IP) networks are one of the fastest growing areas in the field of Information and Communication Technologies (ICT). According to the Cisco VNI Forecast and Methodology (2015-2020) in just last two-year around 90% of world’s data has been created by the digital devices like smartphone, desktop computer, tablets, laptops, surveillance cameras and wireless network sensors. About 80% of created data is the type of unstructured data such as video or images. These digital devices are in the pocket of about 2 billion people worldwide that generate millions of pixels per second.

According to Jon Russell (2015) the unstructured video data is already stored and also users can upload 100 hours of video every minute on YouTube. In addition of stored video over the internet like YouTube, serval surveillance camera also installed stored in the offices, residential houses, roadside and commercial buildings. Owner or user can access these cameras through the internet from the remote and recording can be done online for future investigation. At most organisations, those Internet Protocol (IP) cameras operate 24x7 and stores the recent data for future investigation. A typical organization will create about a Terabyte of big data video every day from different locations around its campus. These digital devices needed high bandwidth connectivity for big data video transmission for video storage in the cloud or online server for analysis.

According to the ITU Measuring the Information Society Report (2016) most people have Internet connectivity and services through broadband, 3G, and 4G networks but many do not use Internet services. A high price, poor quality of service (QoS) and other barriers are serious obstacles for latest network Infrastructure deployment and are crucial to getting more users to connect with the digital world. Accesses of reliable data on the Internet are currently not available for the user and a data revolution is needed to better understand who uses the Internet, where and how. According to Tjekero Tweya (2017) Minister of ICT, Budget Speech, during this financial year (2017) Telecom Namibia plans to implement a number of programs including the replacement of obsolete technologies, critical maintenance projects, high-speed broadband fiber to the customers, enhancement of its operating and business support tools and 3G/4G mobile roll-out of 60 more base stations. The Minister of Information and Communication Technology (MICT), Namibia will continue to oversee and facilitate ICT infrastructure development through the upgrading and expansion of modern, affordable and reliable ICT Infrastructures and services which are imperative for economic development and global competitiveness (Tweya, 2017). Namibia Government, are committed to delivering high-speed broadband to all corners of Namibia and the establishment of e-health, e-education, e-agriculture, e- transport, and e-mining will be facilitated during this coming financial year.
