Abstract
The COVID-19 lockdown has led all the citizens (mobile subscribers) of India to stay at home and rather work from home. The people have started consuming more channel utilization (in mobile communication) through a continuous long duration conversations and more internet data through more streaming content as well as logging on to work from home. It was also reflected in how data demand from residential areas rose as compared to commercial areas. Consequently the bandwidth and channel saturation has evolved out to be a severe problem thereby affecting the work performance of all online offices and multi-national companies. This research paper proposes the simulation based experimental study of DITMC technique for mitigating this effect with a special concern in North Western Rajasthan part of India. The simulation results show that significant enhancement of 60.52% in channel utilization and bandwidth optimization is possible with negligible overhead of 0.23%. This technique also enables the telecom operators to ponder research in this field that will promisingly lead to manage augmented number of mobile subscribers (independent of any lockdown period) in limited bandwidth thereby using the spectrum efficiently.
Highlights
The information from the Department of Telecommunications (DOT, India) demonstrated that between March 22 and March 28, Indians expended a normal of 307,963 TB or 307 petabytes (PB) of information
India’s web utilization rose by 13% since the across the country lockdown was set up to check the spread of Covid-19, as indicated by telecom service information that demonstrated Indians expended 307 petabytes (PB) or 307,963 terabytes (TB) of information every day on a normal for the week starting March 22
The results show that a considerable amount of time is wasted during the conversation in silence period as well as in the repetition of speech/voice bytes
Summary
The Spokesperson of Hotstar, one of the biggest market covering OTT has said "We are careful about the remarkable and intently observing it" They assured the COAI to reduce the bit rate of the HD streams when the need arise and the HD videos is available only for the subscribers among the 300 million users. Other OTTs like Zee and Viacom 18 and its Voot brand have agreed to the COAI’s logic and started working closely to reduce bit rate according the Indian audience’s data consumption pattern without overstretching the existing bandwidth. To manage this multitude flow of voice and data traffic, an efficient model is required to avoid the poor communication services. The channel space occupied by the redundant and silence bytes in the speech signal can be used for interleaving the data
