ABSTRACT Wireless sensor network is a self-organized wireless network which consists of number of embedded systems like sensor, sink node and hardware components. In wireless sensor network, power consumption, energy efficiency, lifetime of the network are the major concern problems. When communication is carried out through the sensor nodes, lot of energy is drained from the network which in turn makes the falling of lifetime of the network. To improve the lifetime of the network, effective routing and scheduling process should be done in the network. To address the mentioned various researchers come up with various strategies and routing protocols. This paper performs a clear analysis of the selective protocols and gives the illustration of the analysis. The selective protocols include routing and scheduling. Key words: WSN, IoT, Protocols, routing, energy Cite this Article: P. Anbalagan and S.

INTRODUCTION Wireless sensor network is a fastest emerging technology which composed of tiny sensor nodes, sink node. It is a self-configured network where the communication can be carried out among themselves. It consists of tiny sensor nodes which monitors the environmental conditions like pressure, humidity, vibration etc. The data from the sensor nodes are collected and pass to the sink node. From the sink node the data is transferred to the main node or the central location. At the sink node, the collected data get analyzed. The sink node or the base
