Impact of using chirp spread spectrum physical layer and request‐to‐send/clear‐to‐send combined with frame concatenation in the IEEE 802.15.4 non‐beacon enabled mode performance

open access: yesIET Wireless Sensor Systems, 2023
This paper studies the performance improvement of the IEEE 802.15.4 non‐beacon‐enabled mode originated by the inclusion of the Request‐To‐Send/Clear‐To‐Send (RTS/CTS) handshake mechanism resulting in frame concatenation. Under IEEE 802.15.4 employing RTS/

IEEE 802.15.4 Modifications and Their Impact [PDF]

open access: yesMobile Information Systems, 2011
IEEE 802.15.4 is a popular choice for MAC/PHY protocols in low power and low data rate wireless sensor networks. In this paper, we suggest several modifications to beaconless IEEE 802.15.4 MAC operation and evaluate their impact on the performance via stochastic modeling and simulations.
