IET Software, Volume 2026, Issue 1, 2026.Directed acyclic graph (DAG)‐based blockchain is a promising paradigm of a blockchain system. During DAG‐based consensus processes, nodes generate blocks in parallel, as well as voting YES on the previous blocks. It makes the DAG‐based blockchain a performance advantage in terms of confirmation delay and transaction throughput.

Analysis of Energy Efficiency Considering Device-to-Device (D2D) Communications in Cellular Networks [PDF]
The Journal of Korea Information and Communications Society, 2013 This paper proposes an energy-efficient mode selection and power allocation scheme in device-to-device (D2D) communication system as an underlay coexistence with cellular networks. We analyze the energy efficiency which is defined as the summation of the energy efficiencies for all devices. The proposed scheme consists of two steps. First, we calculate
