Wireless sensor network is a network of randomly distributed autonomous sensors to oversee different environmental conditions. Contemporary enhancements in the field of wireless communications, memory, processor and radio technology have enabled the growth of low-cost sensor networks and sensor nodes which is proficient in sensing, communication and calculation. These sensor networks have tremendous applications in the various fields of life (Medical, military, industry, surveillance systems, etc. ). Because of this large number of applications, there are copious routing protocols and techniques under which these sensor networks are accomplished. This survey presents the current state of the art of WSN's, a collective knowledge of those routing protocols (S-MAC, MAC, IEEE 802. 11, LEACH, and SPIN) and energy efficient techniques (clustering technique, directed diffusion technique) which are being implemented for their competent functioning. Further, those routing protocols will be discussed briefly and their different aspects and characteristics will be compared. Finally, a better idea among all these routing protocols and energy efficient techniques for WSN's will be presented.
