The analysis and implementation of AllJoyn based thin client communication system with heartbeat function

摘要

The interconnection of heterogeneous networks becomes a bottleneck in the development of the IoT. The birth of AllJoyn is just to solve this problem. At the same time, embedded devices with a specific function or a small number of functions occupy a large proportion in the IoT, how to achieve interconnection with resource limited devices becomes very important. In this paper, we divide the AllJoyn based IoT devices into two parts, one is AllJoyn Standard Client (AJSC) and the other is AllJoyn Thin Client (AJTC). We will compare AJTC with AJSC in AllJoyn distributed bus, communication flow and their architecture. This paper also points out the problem in AllJoyn thin client communication, and proposes a heartbeat mechanism for devices with online detection. Finally, we achieve the interconnection between AJTC and AJSC in a system prototype.
