This paper presents an optimized geometric greedy router (GGR) based on quantum dot cellular automata (QCA) technology. The proposed structure of GGR is based on a spanning tree of the network. This type of communication does not require an IP address. It uses only local information and can be used in many communication devices. In this paper, we first describe the principal components of the router and then we present their QCA architecture. The QCA technology is the most likely alternative to replace conventional circuits (CMOS) due to their very low power consumption and high processing speed. To consider integration with other complex circuit, we have utilized QCA clock-phase-based technique for the proposed design architecture. The results obtained using the QCA designer tool exhibit the superiority of the presented architecture over the existing designs. The proposed structure shows a reduction of 30% reduction in occupied space. The power dissipation rate of the proposed design is analyzed by QCAPro tool to approve its reliability.

Quantum-dot Cellular Automata (QCA) nanotechnology is an interesting circuit design technology which is based on columbic repulsion and Majority logic. Reliability is a key issue in QCA circuits. In this work, an adder is proposed with better fault tolerance and reduced complexity by combining 3-input majority logic and 5-input majority logic gates. The proposed design is realized by using clock zone approach. Hence, the proposed design deploys only normal cells for its realization. This makes the proposed design less vulnerable to fabrication faults. This is validated by performing extensive fabrication defect analysis. A novel expression to compute the circuit complexity is also proposed. The proposed multipliers consume almost 55% lesser energy compared to the existing designs. The proposed adder is used to realize a reliable array and serial multiplier. The proposed adder can be used in any circuits at the basic elements.
