A SECURE DATA AGGREGATION TECHNIQUE IN WIRELESS SENSOR NETWORK

The availability of low cost and tiny sensor devices have resulted increased adoption of wireless sensor network (WSN) in various industries and organization. The WSN is expected to play a significant role in future internet-based application service and increased use of wireless devices such as Bluetooth, Wi-Fi etc which requires efficient security and routing design. Due to battery constrained the network performance such as security and device lifetime will get reduced, recharging and providing security of the sensor nodes in unattended environment is very difficult. Routing the Data in sensor nodes plays a vital role in transferring the data to the base station (BS). Different types of routing algorithm have been used such multi hopping, grid based, hierarchical based and clustering based such LEACH, HEED etc... The existing LEACH protocol is designed so far does not consider security as an issue. In this we have focused on incorporating clustering technique based on hierarchy technique namely EEHC-ECC clusters optimization to provide security and improve the lifetime of the sensor nodes. We compare our proposed clustering model with LEACH protocol and analyze its efficiency.
