Integrity of Data Discovery and Dissemination to Improves the Quality of Service (QoS) in WSNs
Data dissemination is the process by which queries of data are routed in the sensor network. The data collection by sensor nodes has to be communicated to the base station or to any other node interested in the data. Data discovery and dissemination protocol for WSNs is responsible for updating configuration parameters of and distributing management commands, to, the sensor nodes. All existing data discovery and dissemination protocol suffer from two drawbacks.
First, they are based on the centralized approach; in centralized approach only the base station can distribute data items, such an approach is not suitable for emergent multi-owner--multi-user wireless sensor networks. Second, those protocols were not designed with security in mind and hence adversaries can easily launch attacks to harm the network. This paper proposes the first secure and distributed data discovery and dissemination protocol called DiDrip. It allows the network owners to authorize multiple network users with different privileges to simultaneously and directly disseminate data items in to the sensor nodes based on the design objective we propose DiDrip. This is the first distributed data discovery and dissemination protocol, which allows network owners and authorized users to disseminate data items into WSNs without relying on the base station. Moreover our extensive analysis demonstrates the DiDrip satisfies the security requirements of the protocol. Here implements the multi hop data transmission in the network while transmitting data prioritization given to the data. There are three types of data packets low, medium and high by using dynamic scheduling algorithm and improves the quality of service.
