HETEROGENEOUS LEACH PROTOCOL WITH SINK NODE PROTECTION IN A WIRELESS SENSOR NETWORK

Abstract
Sensor Network (WSN) is the group of sensing computing and communication components that gives ability to sense a physical phenomenon in a specified environment. The main problem of WSN is energy consumption or battery power, to avoid such problems different type of routing protocols is used. LEACH routing protocol is used to reduce the energy consumption and enhance the battery power and network lifetime. Homogeneous LEACH has some limitation and there is no security provides to sink node. To overcome this limitation of Homo LEACH protocol heterogeneous LEACH protocol with sink node security is used in this paper. In a heterogeneous LEACH two or more different types of nodes with different battery power and functionality are used. Sink node is a sensor node which has large energy capacity and it collects data from other node. Sometime sink node affected by different type of attack such as sinkhole, black hole attack etc. to avoid these types of attack various technique are used such as intrusion detection, watchdog scenario etc.
