Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Internet Engineering Task Force in March 2012 approved the routing protocol of IPv6 for lossy and low power networks (RPL) as the normal routing protocol for the Internet of Things (IoT). From then, it was utilized in various IoT applications. Although RPL significantly meets the IoT network needs, some open challenges still exist as it was not primarily planned for IoT applications. Though, collecting a huge deal of data from these networks with videos and images often result in traffic congestion within the central network area. For solving this problem, our study suggests the content-centric routing CCR-based RPL, in which the content determines the routing pathways. A larger ratio of data aggregation can be attained through routing the related data to the middle relaying nodes for processing, therefore, the traffic is effectively produced within the network. Consequently, a significant reduction in latency can be obtained. Furthermore, the energy use is predominantly reduced on wireless communication thus preserving the restricted battery. Further integration was performed between CCR and the IETF RPL protocol and applied within the MATLAB platform. Ultimately, both implementation and simulation results demonstrate the greater behavior of CCR-based RPL based on the high packet transferring rates and decrease the numbers of dead nodes, low delay rates, and high energy efficiency in transferring
Currently, Device-to-Device communications (D2D) communication plays an important role in communication, as it increases the efficiency of the use of network resources. This allows the devices to communicate directly with each other, without using the transmission nodes. It is also one of the solutions to the problem of limited network coverage, which can be extended with D2D, and therefore costs and energy can be reduced. This article compares various resource allocation solutions - one of the three main D2D communication problems (D2D detection, connection mode selection and resource allocation). There are two operating modes: the controlled mode (supported by the base station eNodeB) and the autonomous mode
