Building the Web of Things: Challenges and Opportunities for Machine Connectivity

The Internet has changed. It is no longer a tool of communication among people but rather an avenue through which many devices can communicate. This is called the Internet of Things (IoT). However, in the midst of exploring IoT, there is another concept- the Web of Things (WoT). Unlike its predecessor, WoT aims to seamlessly integrate IoT devices into the fabric of the World Wide Web. This way we can achieve even more accessibility and interconnectedness between machines.

This is far from being a simple task though. In fact, it has numerous challenges and opportunities.

The Challenge of Interoperability

One major barrier to building a Web of Things lies within machine connectivity. Unlike traditional web services, IoT devices come in all shapes and sizes with varying functions. They even have different communication protocols as well as data formats hence uniting them becomes difficult aiming at creating a cohesive web across everything.

HyperText Transfer Protocol(HHTP)and Resource Description Framework(RDF) are two standards that assist in achieving interoperability in WoT whereby developers can use them to create uniform interfaces for IoT devices. Consequently, these allow seamless interaction amongst any networked thing.

However, this remains tough because older equipment may not be able support contemporary protocols hence backward compatibility mechanisms need to be put in place.

Security and Privacy Concerns

Considering how much stuff you can attach on a network one must think about security risks that follow as well privacy concerns when using it.

It becomes more critical when viewed from security perspective; every connected device becomes an entry point for cybercrimes thereby making it necessary to have solid protection measures across all connected devices since vulnerabilities will be exploited by attackers who aim at compromising your whole network.

Dealing with these issues would necessitate several approaches including device level security measures, network encryption protocols as well as strict access control mechanisms because they expose those devices which form part of the WoT ecosystem to vulnerabilities thus making it difficult for the entire system to be trusted.

Scalability and Resource Constraints

What we currently have as the internet is well-known as edge computing. This means that data is processed at the source rather than relying on centralized cloud servers. Proven to reduce latency, minimize bandwidth consumption and enhance overall responsiveness of IoT connected devices.

Nevertheless, doing this for every device does not necessarily solve all problems. Specially, when considering devices with limited processing power, memory capacity and energy sources.

In order to keep the Web of Things scalable and long-lasting though, efficient communication protocols and resource management strategies are still needed. However, such overhead associated with transmitting data over constrained networks can be reduced by adopting lightweight communication protocols like Message Queuing Telemetry Transport(MQTT).
