3. PROBLEM DEFINITION
In this Existing System of wireless sensor system included spatially conveyed
gadgets utilizing remote sensor hubs to screen physical or natural conditions, for
example, sound, temperature, and movement. The individual hubs are equipped for
detecting their surroundings, handling the data information locally, and sending
information to one or more gathering focuses in a WSN. Efficient information
transmission is a standout amongst the most essential issues for WSNs. In the interim,
numerous WSNs are sent in cruel, ignored and regularly antagonistic physical
situations for specific applications, for example, military spaces and detecting
undertakings with trustless environment.
DISADVANTAGES OF EXISTING SYSTEM
 Security: LEACH does not solve the security problems which have been proposed
in the proposed system.
 By using the RSA algorithm the size of the key will be more.
 Rekeying will become complex.
 The key distribution cost will be more
