A QoS-geographic and energy aware routing protocol for Wireless Sensor Networks

Recent technological advances in miniaturization and wireless communication have made Wireless Sensor Networks an active research field. The increasing number of multimedia and real-time applications for Wireless Sensor Networks has led to a growing interest in Quality of Service for this category of networks. In this paper, we propose a QoS-geographic and energy aware routing protocol for Wireless Sensor Networks. The proposed protocol performs admission control, accounts for bandwidth requirements and considers the sensors residual energy while taking routing decisions. The protocol also optimizes the delay of carried flows by adopting a selective forwarding approach based on sensor location.
