Wireless Sensor Networks (WSNs) are envisioned to facilitate information gathering for various applications and depending on the application types they may require certain Quality of Service (QoS) guarantee for successful and guaranteed event perception. Therefore, QoS in WSNs is an important issue and two most important parameters that hinder the goal of guaranteed event perception are time-sensitive and reliable delivery of gathered information, while a minimum energy consumption is desired. In this paper, the authors propose an energy-aware, multi-constrained and multi-path QoS provisioning mechanism for WSNs based on optimization approach.
