Data Aggregation Using RSA Key Management Technique in Wireless Sensor Networks

C.Krishnan, Mrs.G.Malathy

Data sampled by sensor nodes having much redundancy. Data aggregation becomes an effective method to eliminate redundancy and minimize the number of transmission and then to save energy. To aggregate data by using ANT COLONY algorithm. Like Ant, it simply collects all the node information and sends to the destination. The ants to explore paths and follow the best paths with some probability in proportion to the intensity of the pheromone trail. In this the Data aggregation scheme employ Dynamic routing protocols and can forward packets(assigning attributes) with key security and time to time key value change dynamically by using RSA algorithm. The resources especially energy in wireless sensor networks (WSNs) are quite limited. Many applications can be deployed in WSNs and various sensors are embedded in nodes, the packets generated by heterogeneous sensors or different applications have different attributes. Most data aggregation schemes employ static routing protocols, which cannot dynamically or intentionally forward packets according to network state or packet types. To make data aggregation more efficient, proposed method using a RSA algorithm to implement a key based data transmission on network. The data’s are aggregated using ant colony, a potential-based dynamic routing is elaborated to support and therefore improve the efficiency of data aggregation. The proposed work is to send the packets through secure routing and time to time key value change dynamically.
