Managing APIs
APIs are very important within WSNs as they help different components of the network communicate with each other. It operates within the application layer, allowing the layer to access the functions of the operating system, such as power management and data collection.
How they integrate within the system
APIs for WSNs can be provided at different levels, including the operating system level and the network level. An example of such an integration is how TinyOS provides an API that allows the application layer to access the functions that are provided by the operating system. At a network level, an API can provide an interface for the application layer to access the routing table, enabling it to find the best path for data transmission to be done. This can be implemented by different standard protocols such as MQTT or CoAP, two application protocols that we discussed in Chapter 3, Integrating Application Protocols.
APIs allow different software components to...
