A Wireless sensor network (WSN) refers to a network of conceptually dispersed and customized sensors which are designed to monitor and record the physical state or conditions of the surrounding and progress the gathered data to a dedicated central location. WSNs are widely used in measuring environmental constrains such as air pressure, temperature, pollution levels, humidity, sound and wind. Because of their inclusive and far-reaching applications, the Wireless Sensor Networks (WSNs) have evolved over the decades. In order to use these kind of networks for different applications the design of energy efficient routing method becomes an important issue because the sensor node's lifespan is very much limited by the battery fuelled devices. As an Upshot, in contemplation of maximise the lifetime of each sensor node, an extensive survey discussing the routing algorithms for energy efficient WSN inspired by natural phenomenon has been brought off in this paper. This paper scouts and inquires a detailed reviewed analysis of already existing energy efficient routing algorithms, with are based on natural science (meta-heuristics) as the basic parameters are connected to energy efficiency as the primary objective. The final section of the paper discusses the limitations of the various algorithms addressed in this paper, as well as suggestions for overcoming them.
