초록

본 논문에서는 무선 센서 네트워크에서 Directed Diffusion을 이용하여 데이터를 신뢰성 있게 전달하는 기법을 제안하였다. 각각의 노드는 자신의 이웃에 대한 정보만을 유지하고 있으나 Interest의 전파 과정을 이용하여 종단간의 전달 신뢰성을 계산함으로써 도달가능성이 높은 경로를 선택하여 전송하는 메커니즘이다. 링크의 에러율과 노드의 개수 변화에 따른 실험을 통하여 제안 방식이 데이터 전달 신뢰성을 향상시킨다는 사실을 확인하였다. 또한, 부가적인 효과로서 트래픽 부하가 분산되고 에너지 소비가 감소되어 네트워크 수명이 연장됨을 알 수 있었다.

Abstract

In this paper, we have pesented a reliable data transfer mechanism using Directed Diffusion in WSNs (fireless Sensor Networks). This mechanism involves selecting a route with higher reachability and transferring data along the route chosen, which is based on the end-to-end reliability calculated by the dissemination procedure of Interest packets, while each node of a sensor network maintains the only information on its neighborhood. We performed various experiments changing the link error rates and the number of nodes and discovered that this proposed mechanism improves event-to-sink data transfer reliability in WSNs. We also found that this mechanism spreads traffic load over and reduces energy consumption, which in turn prolongs network lifetime.
