In wireless communication area, Cognitive radio is an emerging technology which draws attention for more efficient spectrum utilization systems. Cognitive radio is an intelligent mechanism of avoiding interference based on dynamic spectrum sharing. This paper deals with the design, implementation, simulation, and testing of the Smart Radio Channel Change Protocol (CCP). As nearly 80% of spectrum is underutilised, this technique is advantageous to reuse the frequency spectrum. The CCP enables a digital cognitive radio to detect the presence of legacy analog or digital radios, and to facilitate Channel-change procedures to use an alternate, vacant blocks of spectrum. This allows primary and secondary users to co-exist in the same band with minimal interference and improve quality of service (QoS). Here, this wireless network is evaluated using discrete event simulators like OMNeT++. The CCP is also advantageous to other systems’ frequency management schemes due to its simplicity of design and execution.Keywords

Post Covid-19 is a real challenge, as students’ faces are not visible to teachers during interaction or nor the students are available physically, leaving teachers clueless about their active learning and active engagement in learning. Achieving graduate attributes poses further challenge as it has to ensure imbibing Higher Order Thinking skills [HOTs] in students. There is a need to develop online integrated pedagogy to overcome this problem. It is observed that creating content specific videos, really creates interest in students and ensures active learning, if they are asked to upload in YouTube provided students are guided with Rubric based learning for video creation. Moodle integrated YouTube [MIY] channel is developed to let the teachers create their own Video of short duration with rubric guidance. The paper presents a case study dedicated to PO7 [Program Outcome Environment and Sustainability], supported by Open Education for better World [OE4BW]. The Moodle based methodology [73 activities in Moodle- Games like crossword, Quiz, Discussion Forum], integrating with google meet to interact with participants, Rubric guidance, query solving, active learner’s motivation and impact of posting in YouTube channel are presented in study.
Out of 268 participants, 217 participants peer reviewed videos were selected and added in YouTube channel [Environment and sustainability OE4BW, https://www.youtube.com/channel/UCQWwEFdEMeS7Kc 3MuWw3Jkg/videos] based on quality content [Carbon foot print analysis, Environment and Sustainability computation] created by them. Participant’s happiness index for learning was attributed as A+ [4.79/5] during the entire video development process.
