Abstract

In wireless ad hoc networks, packet loss and latency are frequently occurred by movement of node. As the number of transmission hops increases in these networks, the throughput is increasingly deteriorated. In this paper, we design the wireless ad hoc network system based on IEEE 802.16j MMR (Mobile Multi-hop Relay), which improves the network performance. Our wireless ad hoc network system used adaptively the nearest BS and Farthest BS scheduling algorithms for efficient data transmission and chose the optimal path that minimize data loss and latency. In order to evaluate performance of the wireless ad hoc network system based on IEEE 802.16j MMR, we used the LWX (Light Wimax) model of NS-2 simulator. Through the simulation, we analyzed the network performance for various scenarios.

무선 애드 혹 네트워크는 단말의 이동으로 인해 패킷 손실과 전송 지연이 빈번하게 발생하며, 네트워크의 전송 홉 수가 증가할수록 처리율 저하는 더욱 심각해진다. 본 논문에서는 애드 혹 네트워크 성능을 향상시키기 위하여 IEEE 802.16j MMR (Mobile Multi-hop Relay) 기반 애드 혹 네트워크 시스템을 제안한다. 제안하는 무선 애드 혹 네트워크 시스템은 효율적인 데이터 전송을 위하여 Nearnest BS와 Farthest BS 스케줄링 방식을 적응적으로 사용하며, 데이터 손실과 전송 지연을 최소화하기 위한 경로를 선택한다. 제안한 무선 애드 혹 네트워크 시스템의 성능 분석을 위하여 NS-2 시뮬레이터의 LWX (Light Wimax) 모델을 수정하여 제안하는 시스템을 구현하였으며, 실험을 통해 다양한 시나리오에 대한 네트워크 성능을 분석하였다.
