Experimental Results of a Raspberry Pi Based WMN Testbed for Different OSs in Indoor Environment Considering 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 and OpenWRT OSs. We analyze the performance of Optimized Link State Routing (OLSR) protocol in an indoor scenario. For evaluation we considered throughput, Packet Delivery Ratio (PDR), delay, jitter and hop count metrics. The experimental results show that the testbed mounted in OpenWRT has better results than Raspbian.
