在本論文中,將在位置知覺(location awareness)的前提之下,試著減緩無線ad hoc網路上的廣播風暴(Broadcast Storm)問題。所提出的方案有三,分別為RS(Relay Set)、NC(Neighbor Coverage)與TO(Transmission Order)。隨後並以環境模擬的方式,與其他現存解法討論與比較。以模擬結果得知,RS+TO方案在各方面(reachability, saved rebroadcast, latency)表現均為最優,為目前最佳解法。
In this paper, a reachability-guaranteed approach for reducing broadcast storms in MANET is proposed. The approach is based on location awareness of each node, which means each node in the network needs to equip the positioning device like GPS and exchanges location information in the HELLO message with its neighbors. Three mechanisms are included in the proposed approach: Relay Set (RS), Neighbor Coverage (NC), and Transmission Order (TO). RS is a sender-based mechanism in which the sending node of the broadcast message determines the relay set of its neighbors for rebroadcast according to the radio coverage of the neighbors. The idea of the received-based NC is: a node receiving a broadcast message does not have to rebroadcast the message if all its neighbors have received the same message. TO requires a farther neighbor node away from the sending node to rebroadcast the message earlier than nearer nodes so that the nearer node may have more chances to save the rebroadcast. Simulation results have shown that the proposed approach “RS+NC+TO” has a better performance than existing solutions like threshold-based schemes and angle-based scheme in terms of 100% reachability, more saved rebroadcast, and shorter average latency.
