基于模糊控制和MIMO的ad hoc网络STDMA协议
STDMA protocol based on fuzzy control and MIMO for ad hoc networks
摘要
Abstract
In the traditional Space Time Division Multiple Access (STDMA) protocol, the time slot is not allocated dynamically and the idle slots potentially exist. To address the issue, based on fuzzy logic control and Multiple Input Multiple Output (MIMO) technology, a novel STDMA protocol (MIMO-STDMA) is proposed. In MIMO-STDMA, the number of slots and the frame length allocated to a mobile node are determined dynamically through the judgment and calculation based on regulation of the fuzzy controller. Utilizing the reservation and stream control gain of MIMO, in the allocated slots, a node employs full antennas to transmit data. On the contrary, in the unallocated slots the node reserves the transmission by 4-way handshaking with the carrier sense. Finally, simulations are conducted to evaluate the performance of the proposed protocol. The results show that the MIMO-STDMA outperforms the STDMA in terms of throughput and slot utilization.关键词
