초록
MANET(Mobile Ad hoc Network)은 두 대 이상의 이동 무선 단말로 구성되는 네트워크로 단말의 한정된 에너지 때문에 많은 제한성을 가지게 된다. MANET에서 특정 노드들의 조기 에너지 소진은 네트워크 성능에 큰 영향을 줄 수 있다. 본 논문에서는 이에 대한 해결책으로 송, 수신지 사이에 가능한 많은 노드 비중첩 다중 경로를 구축하고, 각 경로상 노드가 가진 평균 에너지, 최소 에너지, 혹은 에너지 분산 값에 따라 다중 경로를 통해 패킷을 분산 전송한다. 에너지 정보 수집 방법을 크게 Static 방식과 Dynamic 방식으로 나누며, 수집하는 에너지 정보에 따라 Static-Average, Static-Minimum, Static-Variance, 그리고, Dynamic-Average, Dynamic-Minimum, Dynamic-Variance 등 6가지 방식으로 나누고, NS2 시뮬레이션을 통해 그 성능을 비교하고 평가한다.
Abstract
MANET(Mobile Ad hoc Network) is a collection of two or more nodes equipped with wireless communications and constrained by the factor of energy limitation. The running out of energy on some nodes may bring down the performance of network seriously. For solving the problems above, this paper uses completely separated Node-Disjoint multipaths from a source to a destination as many as possible. And, based on average, minimum or variance of energy values on the each multipath, the packets are distributed on paths. Generally, collecting methods for energy information can be classified into two main categories, Static and Dynamic. As the different energy values collected, the packet distribution methods are classified into six criteria, Static-Average, Static-Minimum, Static-Variance, Dynamic-Average, Dynamic-Minimum and Dynamic-Variance respectively. The performance of the packet distribution methods and that of AODV are compared by NS2 simulation.
