“…This also corresponds to the amount of UDP data generated. However, the number of individual transmissions required to disseminate broadcast information is highly dependent on the network topology and error probability [46]. The UDP traffic share could therefore increase in larger networks.…”

WLAN mesh networks are one of the key technologies for upcoming smart city applications and are characterized by a flexible and low-cost deployment. The standard amendment IEEE 802.11s introduces low-level mesh interoperability at the WLAN MAC layer. However, scalability limitations imposed by management traffic overhead, routing delays, medium contention, and interference are common issues in wireless mesh networks and also apply to IEEE 802.11s networks. Possible solutions proposed in the literature recommend a divide-and-conquer scheme that partitions the network into clusters and forms smaller collision and broadcast domains by assigning orthogonal channels. We present CHaChA (Clustering Heuristic and Channel Assignment), a distributed cross-layer approach for cluster formation and channel assignment that directly integrates the default IEEE 802.11s mesh protocol information and operating modes, retaining unrestricted compliance to the WLAN standard. Our concept proposes further mechanisms for dynamic cluster adaptation, including subsequent cluster joining, isolation and fault detection, and node roaming for cluster balancing. The practical performance of CHaChA is demonstrated in a real-world 802.11s testbed. We first investigate clustering reproducibility, duration, and communication overhead in static network scenarios of different sizes. We then validate our concepts for dynamic cluster adaptation, considering topology changes that are likely to occur during long-term network operation and maintenance.

“…In previous works [14,15], we have evaluated by simulations our approach, namely control of broadcast forwarding (CBF). The basic ideas behind were to compute how much CBF can reduce routing broadcast traffic impact on unicast data transmissions and how much rebroadcasts could be saved.…”

Wireless mesh network has recently received a great deal of attention as a promising technology to provide ubiquitous high bandwidth access for a large number of users. Such network may face a significant broadcast traffic that may consequently degrade the network reliability. In this paper, we have focused interest to wireless mesh network based IEEE 802.11s and we have designed a self-pruning method to control and reduce the broadcast traffic forwarding. Our scheme, namely Control of Broadcast Forwarding (CBF), defines two behaviours to manage the broadcasting operation. Routing packets are managed differently from data broadcast messages to avoid afflicting the routing process. The simulations results show that CBF ameliorates the network capacity by reducing considerably the number of redundant packets, improving the end to end delay and providing high reachability and packet delivery ration.

The wireless mesh network WMN based on the 802.11s standard is a new concept that allow to broaden the network coverage in order to maximize the number of client stations, taking advantage of the internet connection.This technology presents several problems about certain levels of the congestion, especially the non-exploitation of the resource parts caused by the unnecessary rebroadcast and the collision between packets in the queues. As a result, we obtain the unfairness of medium access.The problem of the rebroadcast of unnecessary packets is controlled by the rebroadcast control mechanisms. One of these mechanisms had been chosen, that in a recent work they studied the capacity of the network that adopt this mechanism .The conclusions of this work, will allow us to define an algorithm to organize the access of flows to the medium, and give more opportunity to the far nodes to occupy a part of the medium.
