Abstract
The researches inclined towards intelligent behavior of the nature to explore architecture for intelligent systems. Artificial intelligence (AI) brings evolution to computational intelligence (CI) emergence which is highlighted in this article.CI gives a picture of the nature's supremacy of being the ultimate intelligent optimizer for human made solutions. A complete picture of energy awareness factor in CI with respect to wireless sensor network (WSN) is also explained. Bio inspired computing escorts us towards the era of bio inspired optimization techniques which enables the technology to handle issues in an optimal and reliable fashion. It ultimately helps to optimize other issues in WSN. The ideology behind making CI the choice of the hour instead of AI for solving energy aware routing is the features which prevails its authenticity and adoption of hybrid approach using different classes of CI to achieve more deterministic and optimized results. Last but not the least researchers are provided with more specific directions and commitment to the solution of energy aware optimized routing in WSN with a true synergy of CI classes.
