IEEE 802.15.4 protocol provides real-time guarantees by using the Guaranteed Time Slot (GTS) mechanism, which is quite attractive for WSNs. Current consumption is a key aspect for evaluating the performance of a Wireless Sensor Networks (WSNs). This paper investigates the battery energy consumed for the different current draw parameters: transmit mode, receive mode, sleep and idle mode keeping other parameters like: initial energy and power supply same for all motes. This paper concludes that there is trade-off for the use of various motes at different types of devices in IEEE 802.15.4 WSNs.
