Performance evaluation Manet test bed on linear topology / Mohd Hafidz Khalili Rohin

Recently MANET has become a rapidly growing research field. There are many new researches and most of the researches is done by using simulation method. However when performing MANET in real environment can be difficult because of the incompatibility issues of hardware and software. The objective of this research is to implement MANET in the real environment is known as test bed. OLSR routing protocol is selected as network protocol and the testbed are run on linear topology where nodes are in a linear position. The testbed consist three scenarios. The first scenario is a linear. The second scenario is linear too but has wider distance than scenario 1. The third scenario is forwarder scenario. Node 1 connects to node 3 via node 2(forwarder node).The performances of this three scenarios are evaluated based on the three-parameter network performance which is throughput, delay and packet loss. Experimental results show that scenario 1 show greater performance compare to scenario 2 and scenario 3. In term of throughput, scenario 1 is better than scenario 2 and scenario 3.In term of delay, scenario 2 has lowest delay compare to scenario 1 and scenario 3. In term of packet loss, scenario 1 has lowest packet loss compare to scenario 2 and scenario 3.At the end of this study, future enhancements of this research were also discussed.
