Abstract

The hierarchical routing protocols have been proposed to deal with the path search in wireless multi hop networks in various research works. As we know, hierarchical scheme has high complexity on the topology structure management. Some research works have researched the routing overhead in different routing protocols and others research the memory used by hierarchical cluster network. However, the robustness of the various protocols has not been researched, which means the performance of the networks in the presence of faulty nodes. The purpose of this paper is to investigate the performance of the flat routing and hierarchical routing protocols in ad hoc wireless networks. It is especially important to study the performance of the various routing protocols under some special environments, e.g. some fault nodes occurs in the networks. In this environment, we could study the robustness of different protocols.
