A Data Collecting and Caching Mechanism for Gateway Middleware in the Web of Things
The Web of Things (WoT) is a refinement of the Internet of Things by integrating heterogeneous devices not only into the Internet (the network),but into the Web (the application layer).With the expansion of applications and deviees,WoT Gateway Middleware is hearing more and more pressure from data processing,and therefore the WoT gateway middleware takes more time to respond to the requests of applications.A data collecting and caching mechanism is an effective solution to this problem.In this paper,we begin by describing the gateway middleware architecture with the focus on data collecting and caching functionality.Then the data collecting and caching (DCC) functionality module is diseussed in detail.The DCC module supports three kinds of data collecting and caching modes:fundamental mode,configurable mode and adaptive mode.We finally demonstrate how these three modes work.A SMART HOME system is developed us the implementation to verify and discuss the proposed mechanism.
