Retransmission DBTMA Protocol with Fast Retransmission Strategy to Improve the Performance of MANETs

Abstract:

The Mobile Ad-hoc Networks (MANETs) are often visible to the exposed terminal downside and hidden terminal problem, which exist due to non-transitivity in media access management schemes. This affects the utilization of channel and throughput in media access management protocols, e.g., twin busy tone multiple access protocol (DBTMA). Hence, to improve the fairness and throughput performance of the DBTMA it's very necessary to address the problems related to hidden and exposed terminals. Hence, during this paper, the quality of service (QoS) is improved by enhancing the capability of the DBTMA for higher network service in the MANETs. The proposed method uses associate improved DBTMA referred to as Retransmission twin Busy Tone Multiple Access (RDBTMA) protocol. This is based on two elements namely: busy tones and ready To Send/Clear to Send (RTS/CTS) dialogues. In addition to the current quick retransmission, a strategy is used further to improve its effectiveness. The retransmission strategy is adopted exploitation negative acknowledgment once the collision occurred by the hidden nodes. A hidden node, wherever the collision happens at access purpose, listens to the NACK signal and uses the signal to work out the necessity quick retransmission theme. The proposed method is simulated and compared against existing methods in terms of varied network parameters. The results show that the projected RDBTMA protocol is effective in terms of the improved QoS in terms of network throughput (21.9%), packet delivery magnitude relation (17.8%), 14.9% less packet loss, and 38th less route discovery delay than the existing methods.
