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.

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
one of the most important components in designing An IoT or wireless sensor network nodal is energy resources such as batteries. But this battery is limited and if it runs out it must be replaced. When the battery's energy source is replaced, the IoT or the wireless sensor network nodal is dead. In this paper the authors propose to examine the concept of a Soil micro energy harvester. This concept would be to use the potential energy from the ground and convert it into sufficient electrical energy to be used to power the wireless sensor network nodal. With this concept it can prolonged batteries life and if it possible to recharge the batteries of wireless sensor network nodal, thus prevent the wireless sensor network nodal to be dead during the operation. Using this concept, we manage to generate electricity with potential difference between electrodes at about 0,727 volt based on our experiment and 1,5 volt based on our calculation. Meanwhile for current based on our calculation we can get at about 74,434 microampere
