A brief comparision of fundamental routing methods for Mobile Multihop Networks (MANET)

In this paper are proposed three basic approaches for providing and keeping communication in Mobile Multihop/Ad-Hoc Network (MANET). There are three approaches for solving communication in these networks. Standard approach represented by MANET routing protocols, Opportunistic approach used in Delay Tolerant Networks (DTN) represented by opportunistic routing protocols, and Hybrid approach represented by hybrid (standard and opportunistic) routing protocols. MANET consists from mobile devices, which have different features and can create diverse type of mobile environment. Not all of basic approach can work efficient to provide and keep communication in such environments. From this reason, in this paper are compared three representatives of this approaches (Dynamic Source Routing - DSR, Social Based Opportunistic Routing - SBOR and Hybrid Social Based Routing - HSBR) and verified their usability and affectivity for given MANET environment for simulations. All methods are simulated with different level of mobile nodes velocity. Theoretical assumptions of increasing success of delivery by combination of advantages from MANET and DTN solutions are verified and confirmed based on simulations.
