| Summary: | – Low Power Wide Area Network (LPWAN) is one of
the fastest growing network techniques provides efficient
communciations for smart cities, e-Health, industry 4.0 and
other applications. LPWAN enables long-rang communcaitons
for M2M and cellular IoT networks. Narrowband-IoT (NB-IoT)
is a type of LPWAN developed by 3GPP to connect a wide stream
of IoT services and devices. NB-IoT systems rely on the
mechanism of repeating the same signal every specified period of
time in order to improve radio coverage better than it is in LTE
systems. Repetition process is used to enhance the coverage of
NB-IoT and for upgrade throughput as well. However, increasing
the repetition of the signal significantly may give a negative result
relative to the bandwidth limits. A cooperative relay (CoR) can
be used beside repetition mechanism to helps reduce bandwidth
stress. Moreover, the use of CoR for NB-IoT in physical uplink
shared channel with repetitions will enhance the throughput.
This paper will evaluate the performance of the CoR to enhance
physical uplink shared channel in NB-IoT. The NB-IoT system
model is simulated bu MATLAB to demonstrate the use of
Cooperative relay (CoR) scheme in NPUSCH for NB-IoT for
performance evaluation and comparison of using CoR scheme by
considering metrics like data rate, throughput, and delay. The
results conclude that in using CoR in NB-IoT gives high
performance in overall NoT network throughput. |
