Abstract: In Wireless Sensor Network energy is a vital parameter as the sensor nodes are low power devices. Many energy efficient protocols have been proposed to efficiently utilize the battery-life of the sensor nodes. Hence it is vital to forward the data packet from the sensor nodes to the sink node without any delay. In contention-based Receiver-Initiated MAC protocols this delay is caused by the idle listening which makes the data packet to stay in the nodes for a longer duration. Also due to collision and retransmission it further introduces delay in the network. As it is not aware of the sink node the data packet may end up in looping. In this paper an Enhanced Scheduling-MAC (ES-MAC) protocol is proposed which a sink-aware beacon is scheduling algorithm applied over receiver-initiated MAC protocol, guaranteeing a delay-efficient communication enhances network lifetime. The ns-2 performance evaluation shows the proposed ES-MAC has high throughput and less network latency. Moreover the comparative simulation result indicates that the proposed protocol outperforms the contention-based RI-MAC protocols.
