Experimental Results of a Raspberry Pi Based WMN Testbed for Multiple Flows and Distributed Concurrent Processing

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. Considering mobility of the terminals, routing is a key process for operation of WMNs. In this paper, we present the implementation of a testbed for WMNs. We analyze the performance of Optimized Link State Routing (OLSR) protocol and parallel distributed processing in an indoor scenario. For evaluation we considered hop count, delay, jitter and processing time metrics. The experimental results show that the nodes in the testbed were communicating smoothly. The processing time for node 1 is smaller than other nodes.
