Implementation of Energy Efficient Multipath Routing and Secure Data Aggregation in Wireless Sensor Networks using ARM LPC2148

In Wireless Sensor Network (WSN) number of nodes involved varies from thousand to thousand. Data communication among the nodes creates a lot of research issues. Hence routing is the essential mechanism for providing path and ensures efficient and reliable multi-hop communication. Furthermore, routing is to ensure the transfer rate of data in the network and at the same time aggregation ensures the reduction of transaction rate between the nodes. In the proposed system, Multi cluster architecture is developed and analyzed for enhancing the performance in routing and data aggregation. Supporting nodes are introduced for performing energy efficient multi path routing and secure data aggregation (EEMPRSDA). To achieve it in real time hardware an experimental setup is developed using three LPC2148 processors and corresponding Xbee series 1 wireless interface cards. The secured data aggregation algorithm is developed using privacy homomorphism techniques and implemented in the proposed ARM based sensor nodes.
