Survey on Energy Efficient Routing Protocol in Wireless Sensor Network

Wireless Sensor Networks have an expanded length of applications but there are hurdles with many asserting issues and complications that should be addressed. The power exhaustion of the nodes and the broadening of the network life span are the basic challenges. As the sensor nodes are devices with limited energy, limited bandwidth and limited computing power, so the top interest is always about how to minimize the energy depletion to extend its lifetime and thus the lifespan of the WSN. In the past few years WSNs has achieved an appreciable amount of consideration from both the research associations and the real users. The experimenter also proposed various energy optimization routing protocols to acquire the desired network operations. In this paper there is an endeavor to present a wide analogy of the routing protocols in WSNs focusing on the hierarchical or clustering based routing protocols. Moreover, deriving the pros and cons of each protocol, giving a comparison among them on the basis of parameters like scalability, mobility, power usage, robustness etc. to make it comprehensible and easy to select the most suitable one as per the requirement of the network.
