论文摘要
我们描述了一个新的同步和分布式中型访问控制（MAC），用于多台化无线网络，可为单播连接提供带宽保证。我们的MAC协议基于一个开槽的时间划分多访问（TDMA）体系结构，在以下数据阶段中，插槽对插槽上的多米尼信号传输阶段数据传输。在框架开始时解决论点允许有效利用带宽。我们的协议本质上将TDMA体系结构的好处与IEEE 802.11 Mac协议的分布式预订机制相结合，从而在高负载下表现良好。我们在每个数据插槽之前实施双向握手，以避免死锁，这是困扰802.11的现象。通过理论分析，我们得出了MAC协议实现的系统吞吐量。我们将MAC协议实施到NS-2模拟器中，并通过广泛的模拟证明了它对IEEE 802.11的极佳优势和同步的MAC协议CATA。
We describe a new synchronous and distributed medium access control (MAC) protocol for multihop wireless networks that provides bandwidth guarantees to unicast connections. Our MAC protocol is based on a slotted time division multiple access (TDMA) architecture, with a multi-mini-slotted signaling phase scheduling data transmissions over slots in the following data phase. Resolving contentions at the beginning of a frame allows for effective utilization of bandwidth. Our protocol essentially combines the benefits of TDMA architecture with the distributed reservation mechanism of IEEE 802.11 MAC protocol, thereby performing well even at high loads. We implement a two-way handshake before each data slot to avoid deadlocks, a phenomena that plagues 802.11. Through theoretical analysis, we derive the system throughput achieved by our MAC protocol. We implemented our MAC protocol into ns-2 simulator, and demonstrate its vast superiority to IEEE 802.11 and a synchronous MAC protocol CATA through extensive simulations.
