Abstract
In this report, a study on hierarchical routing protocols for heterogeneous mobile Ad Hoc wireless networks is presented. The main thrust of the investigation is to identify a potential hierarchical routing scheme that is best suited for a heterogeneous tactical Mobile Ad Hoc Network (MANET). Such networks consist of mobile nodes that are characterized by different communications capabilities, such as multiple radio interfaces. The report highlights the benefits and issues of the different routing protocols, namely the H-OLSR and H-LANMAR, as they pertain to a military tactical scenario. We first discuss the context for the use of a hierarchical routing strategy by describing a typical military scenario where a number of platforms are used each supporting link types of varying capabilities. We then discuss the rational for selecting a proactive hierarchical routing scheme for typical tactical MANETs. We discuss in detail the routing algorithms of the two protocols under investigation. Finally we conduct an experimental comparison study between the two routing protocols. Our experiments reveal that H-OLSR outperforms H-LANMAR for most of the group mobility scenarios that can potentially be used in the operation of a tactical MANET.
