An Impact of Jamming Signal on the Energy Efficiency of ZigBee Network Elements.

The paper presents evaluation of the energy efficiency of ZigBee network elements in the presence of disturbances caused by a jammer. The measurements were performed with the use of two Digi XBee-PRO S1 802.15.4 devices and Arduino boards configured for echo tests purposes. The CRJ4000 cell phone and WiFi ISM band handheld jammer was used as a jamming source. The influence of the radio power level of Xbee module during jamming conditions on the communication quality and the energy consumption was measured. Authors proposed the policy of switching the radio power level of Xbee modules in the presence of jamming signal.
