Abstract:

Wireless Sensor Networks (WSNs) are the infrastructure-less multi-hop network which can be self-configured. It monitors physical as well as environmental conditions. WSNs contain of a huge number of nodes and these nodes of WSN have capabilities of sensing, computation as well as communication and are normally multifunctional, low cost & low power. The sensor node sense the data where they are utilized perform computation on that particular data and later communicate it with other nodes. During this process a lot of energy is consumed. The batteries attached to the nodes provide power supply and it cannot be recharged or replaced in most cases, so the energy consumption is limited. Hence the efficient routing protocols should be developed in sequence to maximize networks lifetime energy. This paper focuses on various energy efficient routing protocols which are utilized in WSN and try to develop a new advanced protocol which will outperform all the previous existing protocols. This paper help to analyzes (LEACH) protocols and develops an advanced protocol for its up-gradation.
