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 neighbours

Available neighbouring nodes respond with a clear-to-send (CTS) packet carrying information through which the sender can choose the best relay.Every prospective relay is characterized by two parameters: the queue priority index (QPI), and the geographic priority index (GPI).
