CLUSTERBASED ENERGY EFFICIENT AND APPROXIMATE DATA COLLECTION FOR WIRELESS SENSOR NETWORKS

In Wireless Sensor Networks, unambiguously sending huge amount of data to the destinationleads to several problems. So, the data aggregation is an essential technique in wireless sensor network. Certain application needs to collect data approximately.In this paper, we focus on to collect a data approximately and efficiently with limited energy and also needs to collect data securely. So, we insinuate a technique called ADC (Approximate Data Collection), which divides sensor network into cluster and determine data organization on each cluster head and the data will be approximated at the sink node. In specific, we offer an inception algorithm to approximate the sensor node readings in cluster head. Now-a-days sensor networks are used for security related applications and security is also become main anxiety. The proposed technique is adaptive to environment changes, more efficient and the amounts of message transmission also get reduced when compared to existing techniques.
