A Sidelink-Aided Approach for Secure Multicast Service Delivery: From Human-Oriented Multimedia Traffic to Machine Type Communications

To date, group-oriented communications have been mainly exploited for delivering multimedia services in human-oriented while, future fifth generation (5G) cellular networks, objects will be the main target. Internet of Things (IoT) undoubtedly play a key role 5G wherein massive machine-type (mMTC) feature use case as crucial challenging since IoT connections are predicted to grow heavily next future. boost capacity and energy efficiency, network can leverage device-to-device (D2D) which recognized an effective offloading technique. This is achieved thanks fact that, legacy D2D communications, data directly sent from one device another, avoiding crossing network. Obviously, distributed nature such communication paradigm inherent broadcast wireless channel make it necessary think how secure so called "sidelink" transmissions. work proposes protocol efficient reliable management multicast 5G-oriented scenario, security requirement met. The proposed tailored Narrowband (NB-IoT) makes with aim improving efficiency optimizing resource utilization. In addition, cyber social trustworthiness mechanisms communications.
