Reliable MAC layer multicast protocol in wireless Ad Hoc networks
摘要
Abstract
In order to provide MAC (medium access control) layer reliable multicast in wireless Ad Hoc networks, a new reliable multicast MAC protocol(RMMP) based on IEEE 802.11 is proposed. In this protocol, a sender multicasts a reliable RTS (RRTS) frame and the receivers reply with reliable CTS (RCTS) frames according to the designated sequence. Then the sender sends N reliable DATA (RDATA) frames and the receivers reply with reliable ACK(RACK) frames sequentially after receiving the N-th RDATA frame in which an acknowledgement frame RACK is demanded. The sender then retransmits the lost frames which are indicated in the RACK frame. The network simulator NS-2 was used to simulate to demonstrate the performance of the protocol. The results show that this protocol achieves reliable multicast at MAC layer by providing higher packet delivery ratio and throughput while slightly increasing average end-to-end delay.关键词
