The IEEE 802.15.4 standard is widely recognized as one of the most successful enabling technologies for short range low rate wireless communications. Although it provides all the details of both MAC and PHY layers of the protocol stack, the standard also explains specific methodologies to protect MAC packets through symmetric-key cryptography techniques under several security options. However, the...
Wireless Local Area Networks (WLAN), using IEEE 802.11, and Wireless Personal Area Networks (WPAN), using IEEE 802.15.4/Zigbee standard, share the same unlicensed 2.4 GHz Industrial Scientific Medical band. Co-existence between such wireless technologies within the same frequency spectrum is crucial to ensure that each wireless technology guarantees the desired performance requirements. In this paper...
