Research Paper on Updated Energy Effective Routing Algorithm for Event-Driven Wireless Sensor Networks with Results
Event driven wireless sensor networks are special networks that just need the sensors which can detect the events, gathering information and sending data through a reasonable routing to the single information processing censor called the sink node, usually used in monitoring emergency events in many large-scale severe environments. However, the battery energy of sensors are limited and difficult to be charged or replaced, it requires effective network routing protocols in communication and message passing process to extend their lifetime. In this paper, I propose a real-time, Updated Energy Effective Routing Algorithm to organize the event detected sensors in the event regions into clusters. The algorithm has a full consideration of the sensors’ residual energy, distance, event excited intensity, overall distance of the cluster from the sink node and received signal strength during the three parts: choosing cluster-heads, clustering and establishing routing path. Simulation results demonstrates the effective routing performance of our algorithm, and its network lifetime is much longer than TEEN and WECRA algorithms.
