Abstract

In this paper, we propose a design method to extend certain cognitive radio (CR) MAC protocols originally proposed only for the one hop applications in distributed CR networks to MANET routing protocols. Among several CR MAC protocols, the opportunistic MAC (called O-MAC) and the opportunistic period MAC (called OP-MAC) are considered, and AODV as MANET routing protocol is used. We implement the protocols using OPNET network simulator, and compare the performances in both MAC and AODV routing environments. With the experiments, we analyze the relationship between MAC and routing performances of the CR protocols.

본 논문에서는 분산 무선인지 네트워크 환경에서 단일 홉 적용을 위하여 제안된 CR MAC 프로토콜들을 MANET 라우팅 프로토콜에 적용하기 위한 설계 방법을 제안한다. 고려하는 CR MAC 프로토콜들은 Opportunistic MAC (O-MAC)과 Opportunistic Periodic MAC (OP-MAC)이고, MANET 라우팅 프로토콜로서는 AODV를 사용한다. 이들은 OPNET을 사용하여 구현하였으며, O-MAC과 OP-MAC의 MAC 환경에서의 성능과 AODV를 적용하였을 때의 성능을 비교한다. 이를 통하여 단일 홉의 DCRN 환경을 기반으로 설계된 무선인지 MAC 프로토콜의 성능과 AODV 적용시의 성능의 관계를 분석한다.
