HISTORICAL DATA PROCESSING OF WIRELESS SENSOR NETWORKS DATA TO REDUCE OVERHEAD ON DATA TRAVERSAL (WSNRODT)

The basic architecture of Wireless Sensor Networks is usually a hybrid type where it is a combination of infrastructure oriented and infrastructure less networks. The Communication from sensor to sensor head takes place through peer-to-peer architecture (infrastructure less) and the communication from Cluster Head to Base Station (BS) involves Broadcast Based (Infrastructure Oriented).This Hybrid architecture is to reduce the energy consumption of sensor nodes as it will be depleted soon when each sensor broadcasts sensed data to base station as and when it senses. Hence a cluster head will be elected for each cluster by considering the battery, memory and processing ability [2] [9]. All the sensors will send their sensed data to the cluster head in a peer-to-peer manner. Cluster head recovers the data and generates the signature using elgammal. Base station sends request to cluster heads of high & heterogeneous clusters and can receive the recovered data from cluster head by verifying signature. The encrypted binary packets are accumulated in BS and it is fed to a database after verification of packets from clusters. Citation: D.
