摘要：Problem statement: In mobile ad hoc networks owing to node mobility, broadcasting is expected to be more frequently used to find route to a particular destination, to page a host and to alarm all hosts. The simplest and commonly used mechanism for broadcasting is flooding, where every node retransmits every uniquely received message exactly once. Despite its simplicity, it can result in highly redundant retransmission, contention and collision in the network, a phenomenon referred to as broadcast storm problem. Several approaches have been proposed to mitigate this problem inherent with flooding. However, none of those schemes guarantees minimum redundancy with 100% delivery ratio. Present Approach: The present study proposes a fuzzy-controlled load-balanced broadcast scheme (FLB) in a multi-hop clustered ad hoc network that guarantees complete packet delivery at no redundancy. Each node nj elects its most eligible uplink neighbor ni within its cluster and that uplink neighbor ni has to take the responsibility of transmitting all broadcast messages to nj. Hence, the redundancy is zero. Results: Simulation results show that the proposed broadcast algorithm provides high packet delivery ratio at minimum overhead and minimum delay, w.r.t. other state-of-the-art broadcast algorithms.
