As smart technology is embraced in many cities globally, the need for reliable and widespread connectivity is increasing. Mesh networking offers an innovative solution that can improve the smart city’s infrastructure by offering seamless and robust internet penetration across expansive metropolitan areas.
What is Mesh Networking?
Mesh networking can be described as a decentralised network configuration where nodes (devices or access points) are able to connect to each other in a matted structure. In the event that a node is rendered inactive, the information will redirect to another node instead, thus ensuring a constant connection and an automated self-repairing network.
Why Mesh Networking is Ideal for Smart Cities
Benefit More Reliable Network
Unlike classical centralised-based networks, which are designed using one central core, mesh networks are designed using multiple connectivity core nodes. This means that in the case of the failure of one core node, the rest of the core nodes can still provide the network which is wanted across smart cities.
Broader Coverage Areas in Cities
Mesh networks enable cities to provide blanket internet access, even to marginalised or high-density urban centres. Individual nodes share connectivity with adjacent areas, hence, making them useful for public areas, transport junctions and high-rise buildings.
Lower Latency and Higher Speeds
With reduced distances among nodes, mesh networks are able to cut down latencies and enhance speeds that are ideal for applications requiring real-time data such as traffic control and security management.
How Can Mesh Networking Be Used in Smart Cities
Public Safety and Surveillance
Mesh networking allows streaming video from CCTV cameras, and emergency broadcast systems while always having the security video on standby even in case of disconnections from some areas of the mesh network.
Traffic Management and Public Transport
Traffic lights and bus and train systems can share information that helps control traffic flow and enhance public transport connectivity via mesh networks.
Environmental Monitoring
Mesh networks could also support IOT sensors for monitoring the air quality, noise levels and other sources of pollution around the region. This pertains to the development of environmental policies that are timely and applicable in urban planning.
Benefits of Mesh Networking for Smart City Development
Scalability to Support Growth
A mesh network can adapt and scale along with the city. This means the addition of new nodes to increase coverage areas and networks is not a complex process that requires a complete network change.
Cost-Effectiveness
Mesh networks lessen the dependence on multipoint wiring and single point of infrastructure, and this helps in saving installation and maintenance expenses. This makes mesh networking to be a viable alternative in the development of smart cities.
Enhanced Data Privacy and Security
Mesh networks allow data to be processed on-site instead of moving it to a central server. This reduces the need to secure users’ data, hence, improving privacy.
Challenges of Implementing Mesh Networking in Smart Cities
Network Interference
Wireless interference as a result of extensive mesh structures may degrade the performance of mesh networks. Such issues can be countered by systematically placing the nodes and designating appropriate frequencies for use within these networks.
Initial Setup Costs
Though mesh networking saves operating costs in the long run, the initial setup is likely to be costly since devices and other infrastructure will have to be acquired. This could pose a problem for most small towns or cities with limited funds.
