Wireless Mesh Networks (WMNs) have emerged as a key technology for next generation wireless networking. The performance of these networks depends on routing protocols. IEEE 802.11s is one of the emerged standards designed to build WMNs for the classical standard 802.11. It defines the HWMP (Hybrid Wireless Mesh Protocol) as its default routing protocol which combines the Radio Metric Ad hoc on-demand distance vector (RM-AODV) with a proactive tree building mode. RM-AODV relies on the well known AODV protocol which provides paths by broadcasting path requests. However broadcast to find routing paths consumes much bandwidth and increases the traffic overhead. In this situation broadcast optimization is an ever-present issue. In this paper, the Geographical Hybrid Wireless Mesh Protocol (GHWMP) is presented

“…The proxy concept is used both in HWMP [3] and in RA-OLSR [7] to reduce the amount of information required to route frames to non-mesh stations. In both protocols the discovery of a station's proxy relies on broadcast messages.…”

“…However, the proactive mode is applied to routes only to the MPP, not to other MPs. The 802.11s draft standard, also specifies the RA-OLSR (Radio-Aware Optimized Link State Routing Protocol) [7] protocol, which is a proactive protocol, and may be more suitable than the HWMP in scenarios with higher mesh traffic. It should be noted that the 802.11s is rather flexible, and although it specifies only the two above mentioned protocols, it allows for the use of other path selection protocols, i.e.…”

Abstract-The IEEE 802.11s draft standard defines a mesh network in which frame delivery is done by forwarding the frame through nodes, called Mesh Points (MPs). To make this possible, it specifies two routing protocols: HWMP and RA-OLSR. Both protocols suffer from scalability issues caused by the use of broadcast messages for discovery and update of routes. In this work, we propose a new routing protocol, the DHT-based Cluster Routing Protocol (DCRP), that improves the scalability of 802.11s networks. Our approach is based on two mechanisms: clustering of nodes and DHT-based searching. Clustering allows to reduce the number of broadcast messages required for routing as well as the amount of routing information broadcasted. DHT-based searching is used to make up for the required routing information that is not diffused by the DCRP itself. Some back-of-the-envelope calculations indicate that our approach increases the scalability of the routing protocol.

“…As [25] point out, the medium access scheme of 802.11s is based on traditional 802.11 MAC protocol Enhanced Distributed Channel Access (EDCA), which is designed for 1 hop scenarios and therefore is not a mesh aware access scheme. [26] analyses the general capacity problem of wireless mesh topologies.…”

Abstract. Provision of internet access in infrastructure deficient areas is expected to bring profound economic and humanitarian benefit to developing countries. Notwithstanding, achieving this goal poses an economic and technical challenge. Due to technological and economical reasons cellular networks are regarded to be unable to deliver affordable distribution in the short term. Instead 802.11s wireless mesh networking standard is identified to be a more viable and affordable partial solution to deliver broadband internet in the periphery of developing countries. A general focus is the individual incentive to participate in a mesh network rather than reliance on organisational bodies. This paper designs an architecture and business model for a low cost, low range distribution of internet access. The technical architecture is evaluated using simulation and is found to be viable, but demands optimisation.
