Abstract

At MANET, Broadcasting message transmission makes throughput decrease because all of MANET nodes are participated at retransmitting broadcasting messages. Especially, burst RREQ transmission causes broadcasting message congestion and inter-RREQ transmission delay. In this paper, we propose a RREQ aggregation method applied to the sender node and intermediate node for solving the problem caused by burst RREQ generation. And we analysis performance of the proposed method by examining at the real testbed.

MANET 환경에서 방송메시지는 모든 MANET 노드의 방송전송 참여로 인하여 심각한 전송률저하를 가져오며 특히 집중적 RREQ 전송은 순간적인 방송메시지 폭주를 발생하는 동시에 RREQ간 전송지연으로 이어진다. 본 논문에서는 이와 같은 집중적 RREQ 발생에 따른 문제를 해결하기 위한 방안으로 RREQ 집적 방법을 제안하며 송신 노드와 통신 경로상 중간 노드에서 각각 집중적 RREQ 발생이 일어날 수 있는 상황을 실 MANET을 구성하여 실험적으로 분석한다. 또한 RREQ 집적 방법이 적용되었을 경우 고려되어야 할 사항을 고찰하며 시험을 통하여 그 성능을 분석한다.
