Nanobiotechnology is a rapidly advancing area of scientific and technological opportunity that applies the tools and processes of nanofabrication to build devices for studying biosystems. Dendrimers are one of the main objects of this new area of science. Dendrimers are recognized as one of the major commercially available nanoscale building blocks, large and complex molecules with very well defined chemical structure. Circulant networks have been used for decades in the design of computer and telecommunication networks due to their optimal fault-tolerance and routing capabilities. Graph embedding has been known as a powerful tool for implementation of parallel algorithms or simulation of different interconnection networks. An embedding f of a guest graph G into a host graph H is a bijection on the vertices such that each edge of G is mapped into a path of H. The wirelength (layout) of this embedding is defined to be the sum of the lengths of the paths corresponding to the edges of G. In this paper we obtain the minimum wirelength of embedding circulant network into nanostar dendrimer. Further we study the embedding of faulty circulant network into nanostar dendrimer.
