Event reporting in Wireless Sensor Networks (WSNs) has always been a major challenge in terms of energy consumption. Event reporting requires sensing the event and sending a reporting packet from the sensor to the centralized base station (BS). However, sensor's energy is limited and stored in a non-rechargeable battery. Therefore, several event-reporting (or data collection) protocols have been proposed to improve energy consumption in WSNs, and consequently, to extend their lifetime. In this paper, we propose an efficient event reporting protocol for WSNs which mainly aims at reporting any event by no more than one sensor node such that energy saving is satisfied in the whole network. To achieve this goal, our proposed protocol is mainly based on the following features: it is a cluster-based protocol, it is a multi-hop routing protocol, it applies distributed data aggregation, and it employs variable clustering and cluster head selection. Simulations show that our proposed protocol significantly extends the lifetime of WSNs compared to other related protocols.
