This paper proposes a fast forward medium access control protocol (FFMAC) for quality-of-service (QoS) guarantee in multihop IEEE 802.11s wireless mesh networks with multiple channels. To the best of our knowledge, the proposed protocol is the first one which considers the multihop and multichannel issues simultaneously. It provides higher priority for real-time applications, while remaining the distributed...
In this paper, we evaluate network performance of non-acknowledged packet transfer in relatively large IEEE 802.15.4 network. Network under consideration contains six interconnected IEEE 802.15.4 beacon enabled network clusters in triangular topology using slave-slave (SS) bridges with CSMA-CA access. We investigate the interactions among local nodes, local bridges and remote bridges. Simulation results...
