Efisiensi Energi Sistem Komunikasi Kooperatif Multi-relay Quantize and Forward Berdasarkan Pemilihan Relay
Abstract: Currently, the
increasing energy consumption is a global issue. Information technology and
telecommunication industry is one of the areas with the largest energy
consumption. The growth of mobile data users is an issue and the biggest
challenge for the future. The cooperative wireless communication system has
been the focus of research as one of the information delivery strategy with
more efficient energy consumption. Energy efficiency in the cooperative
wireless communication system can be improved by using a relay between base
station and user device, where the distance between base station and user can
be shortened, thus, the energy transmission can be minimized. Relay mechanism
can be built by utilizing the protocol in the cooperative communication system,
such as amplify and forward (AF), decode and forward (DF), and quantize and
forward (QF). Relay-selection is an important issue in a cooperative wireless
communication system that can reduce energy consumption at the system level.
This study analyzes energy efficiency of multi-relay QF cooperative
communication for line-of-sight (LOS) and non-line-of-sight (NLOS) environment
based on relay selection strategies: reactive and proactive relay selection. A
computer simulation is conducted based on a system model and mathematical
analysis. Energy efficiency is calculated based on power consumption of signal
transmission and observed in the distance between the source, relay, and
destination. Simulation result shows that multi-relay QF networks with relay
selection consume lower energy than without relay selection, hence, the energy
usage in the relay selection networks is more efficient. Moreover, the strategy
of proactive relay selection provides low energy consumption and high energy
efficiency compared to the reactive relay selection strategy.
