IEQGOR integrates awake and sleep schedules, MAC, routing, traffic load balancing, and back-to-back packet transmissions. A promising routing scheme in Wireless Sensor Networks (WSNs) is shifting toward duty-cycled WSNs in which sensors are sleep scheduled to reduce energy consumption. Nodes alternate between awake/asleep modes according to independent wake-up schedules with fixed duty cycle d. Packet forwarding is implemented by having the sender polling. The availability of awake neighbors by broadcasting an RTS packet for jointly performing channel access and communicating relevant routing information.
