DTN(Delay/Disruption Tolerant Network)에서 라우팅 프로토콜은 전송 지연 및 성공적인 전달 확률의 성능을 개선하기 위해 중요하다. 이 논문에서 우리는 이동성 유형 기반의 라우팅(MPR ; Mobility Pattern based Routing)이라는 효과적인 DTN 라우팅 알고리즘을 제안하는데 이는 이동 노드의 이동성 유형에 근거해 복사되는 메시지의 수를 제어하게 된다. 또한, 우리는 인간 이동성 유형을 가장 잘 나타낼 수 있는 확산성이 매우 큰(super-diffusive) 성질을 가지는 실제적인 “Levy Walk" 이동성 유형을 고려하였다. 우리는 제안된 MPR 알고리즘과 Levy Walk 이동성 유형의 검증을 위해 ONE simulator를 이용한 DTN simulator를 구현하였다. 시뮬레이션 결과 이동성 유형이 DTN 라우팅 성능의 정확한 분석을 위해 매우 중요하다는 것과 제안한 MPR이 실제 이동성 유형 하에서 성공적인 전달 확률이나 전송 지연 측면에서 라우팅 성능을 향상시킴을 보였다.
