When operating in beacon-enabled mode, i.e. beacon frames are transmitted periodically by a central node called PAN (Personal Area Network) Coordinator for synchronizing the network. This paper simulates the collisions at the radio receiver of IEEE 802.15.4 Wireless Sensor Networks (WSNs) for different current draw parameters: transmit, receive, sleep and idle modes, keeping other parameters like: initial energy and power supply same for all motes. Finally, this paper concludes that that Z1 mote should be implemented in IEEE 802.15.4 WSNs as it produces minimum collisions as compared to other motes.
