Description

Wireless sensor networks (WSNs) are widely applicable in monitoring and control of environment parameters. It is sometimes necessary to disseminate data through wireless links after they are deployed in order to adjust configuration parameters of sensors or distribute management commands and queries to sensors. Several approaches have been proposed recently for data discovery and dissemination in WSNs. However, they all focus on how to ensure reliability and usually overlook security vulnerabilities. Sensor nodes can be deployed for communication, monitoring tasks in various fields. In comparison with wired systems wireless sensor networks have their own special features and limitations like energy, storage, computing capability. In Wireless Sensor Network, the security of data and confidentiality of data is an important aspect. Hence the data cannot be interrupted by the intruder. For updating configuration parameters and distributing management commands, data discovery and dissemination protocol for wireless sensor network is responsible. But, it has drawback is that, some protocols were not designed with security. For this reason, The DiDrip protocol i.e. first secure and distributed data discovery and dissemination protocol is proposed. The main function of this protocol is for authorized multiple network user. So, with the help of different security parameters the system provides a high security to the wireless sensor network. Energy efficient new algorithm is also used because it is difficult to crack. Our protocol takes into consideration the limited resources of sensor nodes, packet loss and out-of-sequence packet delivery. Also, it can provide instantaneous authentication without packet buffering delay, and tolerate node compromise.
