| Popis: | Device-to-device1 (D2D) technology in fifth-generation wireless communication (5G) can leverage densely deployed multiple ad hoc networks. Much research has been done to improve QoS, such as throughput, which would decrease because of ad hoc networks' interference with each other. We focus here on the capture effect and its impact on the throughput performance. A contention window control method, ACWA, which improves the throughput of ad hoc networks by exploiting intentional collisions, has recently been proposed thanks to the capture effect. However, the unfairness of throughput between ACWA and the Distributed Coordination Function (DCF) might occur because ACWA could be too aggressive. We propose a modified ACWA method (GSAR scheme) that drastically improves the unfairness and keeps throughput as high as ACWA. GSAR just uses DCF at the sending node and uses ACWA in the rest nodes. In our evaluations considering capture effect, Jain's fairness index resulted in 1.0 from 0.56 in two ad hoc networks with DCF and GSAR. |
