Hybrid Multichannel Wireless Mesh Network (HMWMN) performance analysis using IEEE 802.11

Wireless Mesh Network (WMN) is one of the prominent technologies in the wireless network field. The main goal of WMN is to serve the large community of users with available bandwidth. Hyacinth multichannel architecture is preferable solution for WMN to lever the substantial data and to employ the bandwidth efficiently. The performance of WMN is also depending on the routing protocol to forward the data in the network. The AODV is the most common routing protocol of wireless network technologies and it uses hop count as routing metric. This traditional routing metric is incapable to perform well in multichannel environment. Weighted Cumulative Expected Transmission Time (WCETT) routing metric is well suited for multichannel WMN. In this paper we analyze the performance of Hybrid Multichannel WMN. Two channels are assigned to the nodes and IEEE 802.11 channel assignment strategy is used by HMWMN. Throughput and drop of packets parameters are compared with single channel WMN and HMWMN by varying packet size. We conduct the Chi square test to show the relationship between packet size and throughput. Our results show that HMWMN improves the throughput by 46% and minimizes the drop of packets by 62% than the single channel. HMWMN uses WCETT routing metrics and it is compared against hop count by varying the size of network. Outcomes illustrate that HMWMN has better throughput and End-to-end delay even for large WMN.
