모바일 애드혹 네트워크를 위한 통과 전송 MAC 프로토콜

Abstract

It is important to use a well-designed MAC (Medium Access Control) protocol that uses limited resources efficiently to improve network performance. In this thesis, a pass-through MAC (PT-MAC) protocol for mobile ad hoc networks, in which nodes have two 3-channel interfaces to improve throughput and latency, is proposed. The proposed protocol minimizes end-to-end packet delay in multi-hop routed transmission by using pass-through technique rather than conventional store-and-forward, resulting in improved network throughput as well as lower latency. Conclusively, it significantly improves overall network performance by boosting up the performance of medium access control. According to the performance evaluation result, the proposed PT-MAC shows 20∼44% shorter end-to-end delay and 26∼56% better goodput compared to the IEEE 802.11 DCF with two 3-channel interfaces.
