Abstract

In this paper, we evaluated the performance of OLSR routing protocol in ad hoc network by using test bed method. Evaluation was conducted to know and understand the performance of ad hoc network in certain conditions and scenarios. Ad hoc network nodes were implemented by using Raspberry Pi with USB Wireless TP-Link WN722N. We have done three types of evaluation, such as: evaluate the availability of ad hoc wireless networks in various distance, evaluate the performace of multi hop ad hoc network, and the mechanism of self healing. Each testing is carried out on different circumstances and different scenarios. Based on some testing that already done in this research, it is known that ad hoc network with OLSR routing algorithm can overcome the problem of unreachable link between two nodes. Two nodes in one hop can reach ±180 metres with line of sight condition. Through testing, it is also shown that OLSR can handle the data delivery failures and find a new route to forward the data packets. Finally, to facilitate users in the future, we have remastered raspbian operating system with OLSR packet. It is hoped that users will be easier and faster to implement ad hoc network node with the Raspberry Pi devices.
