The enormous popularity of smart phones and other mobile hand-held devices has led to a dramatic increase in wireless video traffic. Until just recently, there were very few mobile devices with any capability for video reception. According to recent estimations, mobile video traffic is expected to be 60-75% of the global mobile traffic by 2020, and this percentage will only increase with the myriad applications of the “everything connected” Internet of Things upcoming era. However, a number of significant challenges need to be addressed and overcome before the full potential of mobile video networking is reached. Such challenges include, among others:
New sets of traffic control procedures must be implemented in order for networks to cope with the high variance in video traffic Quality of Service (QoS) requirements and guarantee the required Quality of Experience (QoE) for users;
The small display size, limited battery and processing capabilities of mobile devices are constraints which can negatively influence user QoE;
Pricing models for mobile video services;
User discomfort in holding their phones at a set distance from their faces for the time of a video conference;
Compatibility issues between the equipment and the software of mobile video users.
All of the challenges related to mobile video networking are further hindered by user mobility and by the high error rates in wireless networks. Given the small display size, even a relatively low video packet dropping probability may considerably deteriorate the viewer’s QoE. Additionally, errors due to packet loss in a reference frame propagate to the dependent difference frames. Depending on the effectiveness of the encoding/decoding scheme, this phenomenon can have a significant impact on the quality of the received video sequence.
