The Design of High Throughput Wi-Fi Mesh Networked Wireless Sensor Network using OLSR Protocol

We proposed an easily configured Wi-Fi wireless sensor network for mesh topology using OLSR (optimized link state protocol). The system is capable to connect between motes with mesh topology. In order to support high data bitrate, multi applications, multi platform, and secure data connection, we implement the system using Raspberry Pi((R)) with ARMv7((R)) Quad Cores and Wi-Fi interface. For easy of configuration and operation, the system utilized linux based Raspbian kernel 3.18 operating system. The system has been successfully implemented and verified for real-time soil monitoring system. The system implementation only utilized 1% of processor resources and very responsive for topology regenerating. The QoS performance shows the average jitter is 3.87 ms, the throughput is 8.5 Mbps and the Packet loss is 0.019%. In term of range, the system can reach 175 Meter. The result shows that the proposed WSN can be used for high bit-rate Wi-Fi based on application.
