Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

selective receiving.
Support air interface mode SNCP protection for E1 switchover protection.
2.8 RSTP/STP
The NR8250 supports Rapid Spanning Tree Protocol (RSTP) and Spanning Tree
Protocol (STP). RSTP is defined by IEEE802.1w and STP is defined by IEEE802.1d.
STP
It can be used in resolving network looping, where, through certain algorithms,
some redundant paths are blocked and the ring network is adapted into a tree
network without any loop. This prevents broadcast storm in network looping.
RSTP
It is developed on the basis of STP and provides faster convergence speed when
the network structure changes. Compared with STP, RSTP adds two port types:
alternate port and backup port.
RSTP has the following advantages to provide faster convergence speed than STP:
In STP, port state and port role are not clearly differentiated, and the
convergence mainly depends on the switchover of port state. In RSTP, port
state and port role are clearly differentiated, and the convergence mainly
depends on the switchover of port role.
The switchover of STP port states must passively wait for timeout. The
switchover of RSTP port states is an active negotiation.

7.4 N x (1+1 FD) Configuration
1+1 Frequency Diversity (FD) provides frequency diversity hot standby protection.
NR8250 supports 1+1 FD, 2 x (1+1 FD), and 3 x (1+1 FD).
In 1+1 FD protection mode, service can be sent and received through two different
frequency points on the same link, which provides full-time hot standby protection for the
equipment. This mode reduces link attenuation caused by multi-path reflection and
improves link stability.

7.5 SNCP Ring Networking
NR8250 supports Sub Network Connection Protection (SNCP). In SNCP configuration, a
special protection route is arranged in advance for a certain subnet connection. Once
the subnet fails, the special protection route takes place of the subnet and transmits
services for the whole network. SNCP ring network can protect the services transmitted
on the microwave link.
Tip:
SNCP can be configured only in transparent transmission mode.

Detailed description of the SNCP networking is as follows:
The protection path at each transmission direction uses different routes with the
working path (only one signal direction is marked in the figure).
Node A and Node B exchange services through SNCP. That is, Node A transfers
services in bridge mode to Node B through subnet 1 (working SNC) and subnet 2
(protection SNC) respectively.
68. ZXMW NR8250 Product Description
ZTE Confidential Proprietary 2011 ZTE Corporation. All rights reserved. 58
Node B selects the service information from one route by using a changeover
switch based on the changeover principle.
SNCP adopts the working mode of two-route transmission and selective reception.
7.6 RSTP Ring Networking
NR8250 supports Rapid Spanning Tree Protocol (RSTP) ring protection, which protects
services through ring network.

If either the link between site A and site C or the link between site C and site D fails,
the link between site B and site D is unblocked. In this case the transmission path
of service A is site A-B-D.
