Abstract EN
To satisfy the gigantic need for Internet of things (IoT) applications, the third-generation partnership project (3GPP) has revealed the narrowband IoT (NB-IoT) standard.
In any case, collisions in the radio access channel of NB-IoT can be extreme due to the numerous random-access (RA) activates by a massive number of NB-IoTs and the limited available radio resources.
The RA procedure is one of the MAC-layer’s functions that initiates a contention-based setup to grant an uplink transmission.
In this paper, the performance of a new RA procedure is investigated by introducing a modified backoff scheme to reduce the collision probability.
The key mechanism of the proposed scheme is to perform an autonomous approach for determining the time for an NB-IoT to transmit in a collide environment.
The proposed scheme can improve the overall throughput of the network and the NB-IoTs battery lifetime while rioritizing some QoS parameters such as favoring the NB-IoTs with heavier traffic loads.
The probability of collision analysis is subjected to many operating parameters, including the backoff countdown probability, number of NB-IoTs, queue size and the contention window size.
The system and link-level simulations are conducted to assess the proposed scheme with up to five thousand NB-IoTs per cell.
The simulation results showed that the proposed scheme outperforms the conventional approach.
