Wireless sensor networks are limited in energy. Any routing protocol used in wireless sensor networks should take into consideration the time sensitive nature of the traffic in such networks, along with the amount of energy left for each sensor. In this paper we present an energy aware packet delivery mechanism for probabilistic quality of service (QoS) guarantee in wireless sensor networks. Each node takes routing decisions based on geographic progress towards the destination sink, required end-to-end total reaching probability, delay at the candidate forwarding node and residual energy. The simulation results demonstrate that the proposed protocol effectively improves the energy usage efficiency of the sensor nodes, maximizing the lifetime of the entire sensor network, while keeping guaranteed QoS.
