Privacy and anonymity are critical security issues to many large-scale MANET applications such as military communication networks. These applications are
more likely deploying the networks heterogeneously and hierarchically due to
administrative needs or routing efficiency. When the size of the network scales
up, the routing overhead incurred by existing flat anonymous routing protocols
increases fast as the required number of public key operations increases, thus
resulting in deteriorated routing and data communication performance.
In this paper, we introduce a novel
hierarchical anonymous on-demand routing protocol tackling this limitation.
In addition to guaranteeing routing and data delivering security,
the scheme provides two levels of anonymity: intra-group and inter-group.
By exploiting the hierarchical network structure, it effectively controls computational overhead
while preserving anonymity, hence accommodates to larger-scale MANETs.
