Duty Cycle Control Method Considering Buffer Occupancy for IEEE 802.15.4-Compliant Heterogeneous Wireless Sensor Network

This paper proposes a Duty-Cycle (DC) control method in order to improve the Packet Delivery Ratio (PDR) for IEEE 802.15.4-compliant heterogeneous Wireless Sensor Networks (WSNs).The proposed method controls the DC so that the buffer occupancy of sensor nodes is less Personal Care than 1 and assigns DC to each sub-network (sub-network means a netwo
