Abstract
This paper presents the digital logic gates which are reconstructed using fredkin gate [1]. The advantage of basic fredkin gate is that we could save the thermal waste which comes out due to computation that causes heat as bits just disappear into loss of energy. Such computation won't need any energy input. These assumptions make the gates sound like an energy efficient solution. However the implementation is done at level of logic gates. This can further be used in sequential circuits to increase the life time of transmitter and receiver circuitry of nodes. It will make the transmission and aggregation of information at node very energy efficient. The drawback of this application is it will cost fare amount of time to process data. These technical hurdles will increase latencies at node level. The protocols infused with energy optimization methods and reversible logic gates offered noticeable improvements in achieving performance and ensuring security of data and graphics. Since the 1980s, with work of Fredkin [1], the reversible circuits have been used in building large scale integration of circuits as elementary units of mobile computing, and recently in wireless networks, drug designing and ultra-fast computing technologies [4].

This paper presents the digital logic gates which are reconstructed using fredkin gate [1]
It is predicated that power saving using reversible computing can cause remarkable increase in overheads which potentially enhances the impact of energy waste in digital circuit designs again, causing the potential slowdown in technology advancement and restricting research to achieve offered levels of energy efficiency if reversible computing principles are used [2]
This logic is inferred by the second law of thermodynamics which states that the amount of instability faced by system during operations always increases and the result is not reversible
Summary
According to Neuman- Landauer[2] discovery about of the energy dissipated per bit in irreversible operation can be used in further operations by making the system reversibility operation upto some extent. Due to certain difficulties in devising of perfects information of states for data processing and aggregation, allowing researchers to build systems that dissipate much less than kT ln 2 powers in the form of heat becomes a hardship as arithmetic and computational functions that they perform cannot be known perfectly restricting architectural overheads. This saving of energy comes in the form of enhanced network lifetime but with burden of latencies and bandwidth restrictions. Bennett in his research at IBM Research centre showed that any circuit could be made both reversible both logically and thermodynamically [3], and saving more per bit energy in bit manipulations , computation operations per unit of physical energy dissipated
