Abstract: Internet of Things (IoT) Technology rapidly growing area and active research happening in different Layers of Internet protocol stacks. IOT stack have Physical layer& Data Link layer, Network Layer, Transport layer and Application layer protocols and Applications. Now IOT has many applications like Smart cities, Smart Homes, Environmental monitoring, Agricultural Application and Medical data transmission from remote places to expert Hospital. Numbers of IOT Application Protocols (MQTT, MQTT-SN, COAP, XMPP, and HTPP) are available and implemented in rich resource Environments like good computing power and bandwidth. However all Application protocols are not suitable under lossy wireless sensor network environment. In IOT Environment consists of Sensor Nodes, End Systems and related applications. Latency and bandwidth problems exist between sensor node and End Systems in two tier IOT Environment. To resolve this issue, we proposed Three Tier IOT Architecture; it consists of Sensor Node, IOT Gateway /Fog Computing Node, End Systems and Applications. In this paper we proposed flexible design, development and integration of IOT gateway for different IOT applications using MQTT and MQTT-SN Application Messaging Protocols.
Scope of the Article: Wireless Power Transmission.
