Experimental Results of a Raspberry Pi Based Wireless Mesh Network Testbed Considering TCP and LoS Scenario

Wireless Mesh Networks (WMNs) are attracting a lot of attention from wireless network researchers, because of their potential use in several fields such as collaborative computing and communications. In this paper, we present the implementation of a testbed for WMNs using Raspbian OS. We analyze the performance of Optimized Link State Routing (OLSR) protocol in an indoor environment considering Transmission Control Protocol (TCP) and Line-of-Sight (LoS) scenario. For evaluation we considered throughput, hop count, delay and jitter metrics. The experimental results show that the nodes in the testbed were communicating smoothly.
