With the coming wide-spread deployment of Internet of Things (IoT) applications, particularly robustness of the wireless transmissions becomes an issue. We focus on the IEEE 802.15.4 MAC protocol, which has been widely adopted for a variety of Wireless Personal Area Network (WPAN) applications. IEEE 802.15.4 defines a node synchronization strategy using beacons for achieving robust and real-time capable...
Beacon-synchronized operation allows wireless networks to operate very efficiently, in particular focusing on energy requirements. It is, however, unclear, to what extend this beacon-based synchronization suffers in case of independently operating networks with overlapping communication ranges. We study the effects and implications of beacon collisions in co-located IEEE 802.15.4 networks. This protocol...
