Abstract
Mobile ad-hoc network(MANET) is a self-organized network over infraless structured radio links. And hybrid mobile ad-hoc network(HYMANET) is a network which is combined with infra(AP) and MANET. In these networks, one of the most critical problems is the deficient network resource for receiving multimedia streams. The other problem is that overlay connection tree shuts down frequently following mobile node(MN)s’ movement. For solving these problems, this paper generates multi-paths overlay multicast connection tree using multiple parent-child relationships according to the number of hops towards AP(access point) in hybrid ad-hoc network. The proposed method can be used as service for live-video such as news, sports broadcasting image and movies in HYMANET. And this paper can minimize redundant multimedia streams that could appear when supporting multimedia service using multicast.
