초록

무선 애드혹 네트워크에서는 제한된 대역폭, 간섭, 높은 패킷 에러율로 인하여 영상과 같은 고속 데이터 전송 시 높은 전송 품질을 제공하기 어렵다. 본 논문에서는 이러한 제약을 극복하고 고품질의 고속 멀티미디어 데이터 전송을 제공하기 위하여 패킷전송성공률 기반의 종단간 경로 품질과 각 중계노드에서의 잔여 대역폭 예측을 이용하는 PBBR (Path-Quality and Bandwidth-Estimation Based Routing) 프로토콜을 제안한다. 제안된 프로토콜의 성능을 검증하기 위하여 NS2를 이용한 시뮬레이션이 수행되었으며, 시뮬레이션 결과는 제안되는 프로토콜이 기존의 라우팅 프로토콜에 비해 높은 Throughput을 획득할 수 있음을 보인다.

Majority of the wireless ad hoc routing protocols are proposed to find feasible routes without considering the network load, end-to-end link quality and bandwidth requirements of the application. Therefore, protocol may not provide sufficient quality of service (QoS) to a high speed traffic such as multimedia. In this paper, we propose a path-quality and bandwidth-estimation based routing protocol (PBBR) for the high quality multimedia stream that can meet the application's bandwidth requirements and find the best reliable route. The novelty of this protocol is to select a reliable path to respond the application's requirements based on available bandwidth at each intermediate node and end-to-end path loss ratio. Obtained results from the simulation demonstrates that our protocol can achieve sufficient performance in terms of throughput and end-to-end delay.
