2. With the rapid evolution of smart city all over the world, the appealing
services of IoT and big data analytics have prompted the design of more
reliable assurance mechanism for network quality. It has been a crucial issue
of network operation that once multiple links fail simultaneously, the
transmission of real-time services cannot be guaranteed. Therefore, rapid
locating of faults is the premise for network to recover quickly. However,
current faults location methods can’t satisfy the requirement due to the
expansion scale of wireless and optical networks and the growing demands
of customers. In this paper, we propose an efficient multi-link faults location
algorithm based on Hopfield Neural Network (HNN).

3. We make full use of the information of network topology and the services
transmitted to model the relationship between fault set and alarm set. HNN
is used as an optimization method to analyze the uncertainty of faults and
alarms and to find where the faults most likely occur by constructing a proper
energy function. It has been proved by experiments that this method can
achieve real-time faults location while ensuring positioning accuracy, which
provides a good solution for smart city service assurance.

4. As a novel cutting edge technology that proffers to connect a mass of digital
devices endowed with several sensing, actuation, and computing capabilities
with the Internet, IoT is playing a significant role in the context of smart city.
Smart city IoT develops fast with the characteristics of explosive growth in
mobile data traffic, huge number of device connections and continuous
emergence of various application scenarios. New type of services such as
telemedicine monitoring, video-based surveillance and intelligent
transportation put higher demands on network infrastructure and carrying
capacity. Designing a high-rate, reliable and resource-efficient network
framework for smart city IoT has attracted ever-increasing attentions and
become a research hotspot .

5. A large number of users or providers are deploying their services in wireless
and optical networks, which are characterized by supporting higher data
rates, excellent end-to-end performance, and ubiquitous user coverage with
lower latency, power consumption, and cost. Optical networks have a good
performance for the future services transmission in smart city fronthaul
according to its features of high bandwidth and transparent multi-rate traffic
transmission. Therefore, wireless and optical network has already become a
newly research direction as a promising solution for smart city IoT.

18. In this paper, we investigate a CHNN-based multi-link faults location
approach in wireless and optical networks for smart city IoT. Processing
procedure of the directed bipartite graph between suspected faulty links and
alarms is regarded as a combinatorial optimization problem, while the set of
links that are most likely to fail is found out from all the possible solutions of
this problem. Numerical results show that the proposed CHNN-FL algorithm
can achieve rapid locating of multiple links faults while meeting the
requirement of positioning accuracy in large-scale wireless and optical
networks.
