چکیده
Recent advance in wireless communication technology and micro electromechanical system has contain the development of little cost, low power, network-enabled, and multifunctional micro sensors. Due to their easiness of deployment, reliability, scalability, flexibility, and selforganization, the existing and potential applications of wireless sensor networks (WSNs) span a wide spectrum in various domains, the environmental and technical requirements of which may differ significantly. The intention of deploy a wireless sensors are to gather related information for processing and also reporting. In particular, based on data reporting, WSNs can be classified as time-driven, event-driven or data driven. In this paper, a hybrid data-gathering protocol that dynamically switches between the event-driven data-reporting and data-driven data-reporting schemes is proposed. The novel aspect of this approach is that sensor nodes that seem to detect an event of interest in the near future, as well as those nodes detecting the event, become engaged in the adaptive transmission based data-reporting process. This capability enables data from neighbouring areas to be gathered proactively without requiring observer intervention. The two algorithms named PED and PAD the value of the algorithm in a wireless scenario is analyzed. K. Banupriya PG scholar, Dept of EEE, RVS College of Engg & Tech, Dindigul, India K.
