무선 이동 에드 혹 네트워크에서 효율적인 코어-기반 멀티캐스트 트리

다국어 초록 (Multilingual Abstract)

This study suggested a technique to maintain an efficient core-based multicast tree using weighted clustering factors in mobile Ad Hoc networks. The biggest problem with the core-based multicast tree routing is to decide the position of core node. The distance of data transmission varies depending on the position of core node. The overhead’s effect on the entire network is great according to the recomposition of the multicast tree due to the movement of core node, clustering is used.
A core node from cluster head nods on the multicast tree within core area whose weighted factor is the least is chosen as the head core node. Way that compose multicast tree by weighted clustering factors thus and propose keeping could know that transmission distance and control overhead according to position andmobility of core node improve than existent multicast way, and when select core node, mobility is less, and is near in center of network multicast tree could verification by simulation stabilizing that transmission distance is short.
