Investigation of OLSR Behavior for Different Hello Packets Intervals in a MANET Testbed

In recent years, Mobile Ad-hoc Networks (MANETs) have an increased attention on covering rural areas due to the possibility of usage of low-cost and high performance mobile terminals, without having to depend on the network infrastructure. Because the terminals are mobile, the routes change dynamically, so routing algorithms are very important for operation of MANETs. In this paper, we investigate the performance of Optimized Link State Routing (OLSR) protocol for different scenarios in indoor and outdoor environment considering throughput metric. We design and implement two experimental scenarios in our academic environment and compare their performance behaviour for different HELLO packets interval of OLSR protocol.
