Abstract: Existing solutions for reliable data transmission in wireless networks are aimed to offer reliable message or per transport segment delivery. However, densely deployed sensor nodes can generate many redundant messages that essentially indicate the same event from the area of interest, thus this message-level reliability can pose significantly high and unnecessary communication overhead. In this paper, we address the reliability problem by defining event reliability and query reliability to reduce extra cost of reliable transport services. Unlike other studies on transport protocols for Wireless Sensor Networks (WSN), we consider event delivery in conjunction with query delivery. For the purpose, we propose an energy-aware sensor classification algorithm to construct a network topology that is composed of sensors in providing desired level of event and query reliability. We evaluate the performance of the proposed approach and conclude that significant savings on communication costs are attainable while achieving event and query reliability.
