Wireless Mesh Networks (WMNs) with chain topologies are very useful in road and railroad transportation or in tunnel and mine applications. The proposed protocols for WMNs usually support best-effort traffic or some kind of Quality of Service (QoS). However, some applications such as remotecontrolled machines in industrial control networks have Hard Real-Time (HRT) requirements, i.e., strict deadlines. Moreover, voice, video and data communications can be added to HRT traffic in order to provide them with reserved bandwidth and bounded latency. For this reason, this paper presents WICKPro (WIreless Chain networK Protocol), a HRT protocol for WMNs with chain topologies. WICKPro is a token-passing approach and is based on the ideas of the Timed-token protocol and the cyclic executive. We have designed this protocol to work on top of IEEE 802.11, made a testbed using commercial 802.11 wireless cards and compared the protocol's performance with the 802.11 protocol and three specific protocols for WMNs with chain topologies.

“…Then, the average overhead to transmit a data frame, H, is given by H = T ACK + T CTS + 3SIFS. (1) If the data length is fixed, the minimum achievable spatial reuse distance is 4; hence, the maximum number of parallel link is n/4. Let N k be the node sending the largest data packet size S at time t. The probability that there is no packet longer than S and at least one packet has size S is (2)…”

“…In this chain-based multihop wireless network, the node connected to the wired Internet is the gateway (GW), while other access points (APs) act as relay nodes. Hence, the environments are characterized by the multihop radio broadcast, and spatial reuse property can be adopted to improve the network throughput [1].…”

“…It suffers from inefficient usage of network resource due to back-off and packet collisions in the multihop environment. The carrier sense multiple access with collision avoidance (CSMA/CA) algorithm in DCF also omits the spatial reuse properties [1]. Li, et al [3] showed that 802.11 MAC protocol with RTS/CTS can achieve only 1/7 of maximum attainable throughput.…”

It has been shown that IEEE 802.11 DCF medium access control (MAC) protocol may not be suitable for multihop wireless networks due to its relatively low throughput and severely unfairness problems. A tokenpassing MAC protocol, named Ripple, has been proposed to enhance the throughput of DCF by utilizing spatial reuse. However, two perfect assumptions of 'fixed-length data packet' and 'identical interference range and transmission range' in Ripple make it less practical in the real world. This paper proposes an Enhanced Ripple (E-Ripple) protocol aiming to remove the two restrictions. An analytical model is presented to estimate the performance of E-Ripple and the accuracy of the analysis is then verified via computer simulations. The results indicate that E-Ripple performs well in such a non-perfect environment.
