SAFE DATA DISCOVERY AND DISSEMINATION IN MOBILE WSN

Abstract

Wireless sensor networks (WSNs) are widely applicable in monitoring and control of environment parameters. Several approaches have been proposed recently for data discovery and dissemination in WSNs.  WSN routing protocols provide the required functionality but cannot handle the high frequency of topology changes as well as data discovery and dissemination in mobile wireless sensor network. So WSN protocols are not effective. So position based routing protocol like AODV, DSR, AOMDV and DSDV can be used. After experimental evaluation on Network simulator NS2 for Packet Delivery Ratio, Packet drop ratio, routing overhead, network throughput, total received packet, command packet it is found that DSR protocol best suited for secure Data dissemination and discovery.
