摘要

为了支持无线网络中的软实时通信，需要有优先级的MAC协议。为了在多跳无线自组织网络中支持软实时数据流，我们引入了一种新的优先级MAC协议——实时链。通过避免分组冲突和限制优先级反转的影响，实时链能够提供软实时性和带宽保证。此外，多信道的使用可以实现高空间重用和传输速率。最后，我们的方法可以与IEEE 802.15.4标准的稍微修改版本集成。该协议已在Crossbow MICAz硬件上完全实现，并通过大量室内和室外实验验证了其性能

Soft Real-Time Chains for Multi-Hop Wireless Ad-Hoc Networks

Prioritized MAC protocols are needed to support soft real-time communication in wireless networks. In this paper, we introduce real-time chain, a new prioritized MAC protocol to support soft real-time data flows in multi-hop wireless ad-hoc networks. By avoiding packet collisions and limiting the effect of priority inversions, real-time chain is able to provide soft real-time and bandwidth guarantees. Furthermore, the use of multiple channels enables high spatial reuse and transmission rates. Finally, our approach can be integrated with a slightly modified version of the IEEE 802.15.4 standard. The protocol has been fully implemented on Crossbow MICAz hardware and its performance has been validated with a large set of both indoor and outdoor experiments
