The authors propose an enhanced Lightweight Medium Access Control (eL-MAC) protocol which combines scheduled based MAC mechanism and Adaptive Multi-Timeslot Allocation (AMTA). Wireless Sensor Network (WSN) consists of tiny wireless devices typically cooperate with each other to aggregate sensor data to the base station. It is increasingly being used in a wide range of environmental application. Such applications like habitat monitoring, large-scale industrial monitoring and urban population monitoring require years of operation period with low rate data transmission. Hence, providing a reliable data transmission and efficiency in energy usage are critical in order to prolong the network lifetime.
