“…Instead, the location and placement of each mesh STA, AP collocated with a STA, and mesh portal is carefully planned, applying network planning [48] or genetic algorithms (GA) [39]. Nevertheless, grid shape has been widely used by researchers to evaluate the scalability of IEEE 802.11s mechanisms [13,[49][50][51][52] as it provides a simple and controlled environment, allowing a fair comparison of reproducible results.…”

The IEEE 802.11s standard specifies a mesh technology to be supported by IEEE 802.11 devices. Among the limitations caused by this heritage, we focus on the low scalability of the current IEEE 802.11s standard mechanisms. As a main contribution to the related research field, this article presents the DHT-based Cluster Routing Protocol (DCRP). DCRP addresses IEEE 802.11s' scalability issues by exploiting both Distributed Hash Tables and Clustering schemes, which have proved to be effective in scaling wireless (e.g., MANETs) and wired (e.g., P2P) networking systems. DCRP was implemented and compared with the HWMP through simulation for different scalability parameters and performance metrics. Simulation results indicate that the proposed scheme improves performance in terms of packet delivery ratio, end-to-end delay, throughput, and overhead.

“…Moreover, HWMP is evaluated in [10] in terms of loss rate, path establishment delay, network throughput and signalling overhead for a grid wide network topology simulated with 9 to 225 static mesh stations. The performance evaluation of HWMP in [11] is in terms of throughput, end-to end delay and jitter for heterogeneous applications such as VoIP, video streaming, HTTP and FTP for both on-demand and proactive modes of HWMP operation.…”

Mobile ad-hoc networks (MANETs) enable ubiquitous computing with wide availability of smart mobile devices and applications. However, robust and lightweight protocols are yet to be implemented for multihop communication. The latest IEEE 802.11 standard released in 2012 captures the concept of muItihop MANETs under Wireless Mesh Networks and proposes Hybrid Wireless Mesh Protocol (HWMP) as the default muItihop path selection protocol. Previous studies on the performance of HWMP have not addressed operating scenarios of mass mobility (to model human user mobility), non-availability of root nodes (to model absence of infrastructure support) and a wide span of node densities (to model different application scenarios). This paper analyses the scalability of HWMP in a MANET of IEEE 802.11 standard wireless mesh stations that move at human walking speeds. The end-to-end delay, data packet delivery ratio and path selection control overhead are evaluated in the presence of random waypoint and mass mobility models for increasing node densities. The simulation results show that there are no significant variations in any of the above important performance metrics among static, random waypoint mobility and mass mobility models. Furthermore, HWMP shows almost a linear path selection control overhead profile for increasing node densities while the packet delivery ratio and the end-to-end delay reaches a steady level as node density increases up to about 250 nodes.

“…In literature [6,7,8,9], the performance evaluation of HWMP protocol and airtime routing metric are generally done by considering a unique type of flow with fixed packet size and packet rate. However, the real Wireless Mesh Network scenario is quite different.…”

Abstract-Wireless Mesh Network (WMN) have been envisioned as an important solution to the next generation wireless networking which can be used in wireless community networks, wireless enterprise networks, transportation systems, home networking and last-mile wireless internet access. Many proprietary mesh solutions were developed by individual vendor but in order to interoperability; IEEE forms a task group called IEEE 802.11s to develop an integrated mesh networking solution. Hybrid Wireless Mesh protocol (HWMP) and airtime metrics as default routing protocol and routing metrics set by the task group. There is few test bed and many simulation studies have been done to evaluate the performance of the HWMP protocol with the assumption of unique type of flow with fixed packet size and packet rate. However, real networks carry a diverse application (video, voice, FTP, Email etc) with different characteristics (packet size, data rate). In this paper, we are investigated and analyzed the performance of HWMP protocol under such heterogeneous application characteristics.
