Surfing the IoT: Lightweight Access and Control of WSNs Using Industrial Low Power Protocols

Internet of Things

•By embedding short range mobile transceivers into wide array of additional gadgets and everyday items, enabling new forms of communication between people and things , and between things themselves.

•Things will have identities, virtual personalities and intelligent interfaces.

Why IoT?•Dynamic control of industry and daily life.•Integration of human society and physical

systems.•Universal transport and internetworking.

Application areas:• Daily life.• Logistics.• Traffic• Resource and power control.

Key Results

•Implementation of full IPv6 protocol stack on WSN nodes.

•Integration of IEEE 802.15.4 connectivity into open platform gateway.

•Proposes two alternate access methods to enable REST based applications with sensor devices.

Additional layers of internet model for IoT:

6LoWPAN

•IPv6 over Low power Wireless Personal Area Network.

•An open standard.•Provides an adapter between IEEE

802.15.4 and IPv6•Enables interoperability between wireless

embedded devices and common internet devices.

Constrained Application Protocol

•is a specialized web transfer protocol for use with constrained nodes and constrained (e.g., low-power, lossy) networks.

•Compact 4 byte header.•Easy to proxy from/to http.•URI supported.•Built in discovery.•DTLS based security.

CoAP transaction model

HTTP-CoAP protocol implementation

Interaction process of HC proxy
