연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

In this paper, an Ad-hoc Routing Protocol that works in wireless Ad-hoc communication networks with multiple radios and multiple channels and that controls call admission based on bandwidth measurement is proposed. Unlike the conventional Ad-hoc node with a single radio using a single channel, an Ad...

제안 방법

  • In this paper, a new approach is proposed in which multiple radios are used with multiple chann신 s at each Ad-hoc node to resolve the bandwidth problem. Furthermore, the use of a fixed receive-only channel at a fixed radio of each node makes it possible to measure the available bandwidth of a wireless link, as well as making it possible to offer a call admission control, udiich will eventually provide a bandwidth-guaranteed QoS.
  • more difficult. In this study, a routing protocol was proposed that can increase the available bandwidth of a wii긘ess link by the use of multiple radios and multiple champs, and that can provide QoS by admission control based on available bandwidth measurements and an estimation of a wireless link.
  • In this study, the route intra interference requirement was applied during the routing process, making it possible to fully use the capacity of the wireless link.
  • In this study, to perform a call admission control, 2 fields were added in the RREQ packet, the bandwidth requested by a new call, the rBw (requested Bandwidth), and the RoC of the preceding nod e of the node sending the RREQ, pre-RoC(preceding node's RoC). These 2 items were used for making decisions of the 2 call admission requirements paformed in this routing protocol.
  • This study used CSMA/CA as a MAC layer protocol, where an RTS/CTS packet is used for the reservation of the wireless link and the ACK packet is used to confirm the sucse笛sfi과 transmission of data. Also it was assumed that each Ad-hoc node had M(>3) Radios and used an N(>4) channel , including a common control radio(/channel).

대상 데이터

  • During the simulation, a node with 2 IEEE 802.11a network interface cards and 5 interference-free channels(36, 48, 64, 149, 161)[7] was used. It was assumed that the channel switching delay was 1ms.

이론/모형

  • Furthermore, the use of a fixed receive-only channel at a fixed radio of each node makes it possible to measure the available bandwidth of a wireless link, as well as making it possible to offer a call admission control, udiich will eventually provide a bandwidth-guaranteed QoS. The proposed routing protocol is called a MCQosR(MultiTadio and -Channel Qos Routing Protocol).
