Experimental Results of a Raspberry Pi Based WMN Testbed Considering CPU Frequency

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 scenario. For evaluation we considered throughput, Packet Delivery Ratio (PDR), delay, jitter, hop count, idle and CPU temperature metrics. The experimental results show that the nodes in the testbed were communicating smoothly. The performance of tesbed was better for CPU frequency 700 [MHz].
