Modes of inter-network interaction in beacon-enabled IEEE 802.15.4 networks

摘要: Future growth in Internet-of-Things applications will lead to an operating environment with many independent networks the same location. Co-existence and internetwork interference IEEE 802.15.4 is particularly interesting because of popularity radio limited number “good” channels, making it likely that there be nearby on channel. This paper presents in-depth simulation study interaction between beacon-enabled using contention-based slotted CSMA contentionfree GTS allocations. We use simple scenarios intended highlight underlying modes interfering networks. Our results reveal several complex behaviors, including episodes large, slow oscillations throughput long periods disconnection interspersed short bursts high throughput. These have practical implications for design evaluation protocols future IoT environments.
