For the monitoring and controlling of environmental parameters Wireless sensor networks are widely used. The dissemination of data over the sensor nodes in order to adjust configuration parameters of sensors or distribute management commands and queries to sensors nodes is very important. Several approaches have been proposed recently for such query distribution in a secured manner. The DiDrip protocol employs distributed approach to disseminate data items to the sensor nodes. This DiDrip protocol works efficiently as it addresses all the security issues and it can be enhanced for its improved efficiency. The additional changes to the protocol can save energy and make sensor node resistance to DoS attack
