Experimental results of a manet testbed for different settings of HELLO packets of OLSR protocol

In Mobile Ad-hoc Networks (MANETs) the mobile terminals can be used in cooperation with each other, without having to depend on the network infrastructure. Recently, these terminals are low-cost, have high-performance and are mobile. Because the terminals are mobile, the routes change dynamically, so routing algorithms are important for operation of MANETs. In this paper, we investigate the behaviour of OLSR routing protocol for different values of HELLO sending interval and validity time. We conduct real experiments in a MANET testbed. We design and implement two experimental scenarios in our academic environment and investigate their performance behaviour for different number of hops.
