Modelling information generation in event-driven sensor networks

Event-driven wireless sensor networks gain precedence over data-driven networks due to the effective manner in which they reduce the redundancy in data transmitted. In this paper, an attempt has been made to model the events of information generation and dissemination in an event driven wireless sensor network with uniformly distributed sensor nodes. Two existing definitions for the lifetime of sensor network have been used and a comparison of performance metrics like network lifetime, packet throughput and energy utilization have been made. Furthermore the concept of data aggregation has been incorporated into the developed model and the improvement in performance is observed.
