Wireless mesh networking (WMN) is a continuous growing technology that has an important role towards the vision of smart agriculture. This work presents the setup and performance assessment of a wireless mesh network testbed developed within the context of PrunusPós project to collect data such as temperature and humidity of fruit crates or containers when stored or transported in refrigerated chambers. The testbed is based on ESP8266 devices connected in a wireless mesh using the painlessMesh library. A performance evaluation study was conducted with different numbers of nodes, traffic loads, and message payload sizes under unicast and broadcast communication. The impact on network performance is evaluated in terms of delivery ratio and delivery delay. This study will guide the future development of mechanisms, schemes and protocols that provide efficient bandwidth utilization and energy-efficient computing for the PrunusPós project WMN.
