Design on routing protocol in hybrid wireless self-organizing networks

Recently, hybrid wireless self-organizing (HWSO) networks by spatial and ground communication devices has become the focus in future information networks. Due to the characteristics including open medium, dynamic topology, redundancy structure and distributed collaboration, traditional routing protocols in fixed and ad hoc networks cannot be directly used in HWSO network, so that the design of special routing protocol for HWSO networks has become a challenging work. In this paper, we propose a new Hybrid On-demand Distance Vector Multi-path (HODVM) routing protocol that divides the whole network to backbone network and non-backbone network to perform the static routing and dynamic routing, respectively. Simulation results show that, compared to previous routing protocol, HODVM has better scalability as the network size is enlarged or topology is changed.
