Cooperative Relay Based Communication Over Multi User Mobile Networks
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
The importance of energy efficiency is becoming more crucial in today’s mobile communication systems. Cooperative Communication is a technique which aims to increase energy efficiency by the use of relay nodes. Basically, cooperative relaying is a technique for wireless communication which guarantees gains in throughput and energy efficiency. The basic idea is that when a device needs to transmit data to its destination, a third device overhears this signal and then relays the signal to the destination. The destination then combines these signals to improve decoding. This paper aims to prove that a cooperative communication system offers higher achievable rates than conventional communication systems. Then, the energy efficient transmission problem is focussed in a relay-based cooperative network which aims to prove that systems with relay nodes have higher transmission efficiency by comparing it with systems with the same number of source and destination nodes, but without relay nodes. This will help achieve high data transmission over the long distance communication. The disadvantage of the existing system is that it has base station to end user transmission which has low data transmission. This disadvantage can be overcome or improved by implementing cooperative relay based data transmission.
