The OpenWSN project serves as a repository for open-source implementations of protocol stacks based on Internet of Things standards, using a variety of hardware and software platforms.

Motivation

The Internet of Things enables great applications, such as energy-aware homes or real-time asset tracking. With these networks gaining maturity, standardization bodies have started to work on standardizing how these networks of tiny devices communicate.

The goal of the OpenWSN project is to provide open-source implementations of a complete protocol stack based on Internet of Things standards, on a variety of software and hardware platforms. This implementation can then help academia and industry verify the applicability of these standards to the Internet of Things, for those networks to become truly ubiquitous.

Open Source

Our OpenWSN effort at UC Berkeley is one of many open source hardware and software projects for wireless sensor networks. Here are links to some of our friends and colleagues around the world.

Protocol Stack

The standards under development most applicable for the Internet of Things are:

  • The IEEE802.15.4e standard defines MAC amendment to the existing IEEE802.15.4-2011 standard. One mode, called Time Synchronized Channel Hopping, significantly increases robustness against external interference and persistent multi-path fading, while running on legacy IEEE802.15.4 hardware.
  • The IETF 6TiSCH working groups standardizes mechanisms of running an IPv6-enabled protocol stack on top of IEEE802.15.4e TSCH.
  • The IETF 6LoWPAN working group has standardized a mechanism for an IPv6 packet to travel over networks of devices communicating using IEEE802.15.4 radios; this includes header compaction techniques to fit long IPv6 headers into short IEEE802.15.4 frames.
  • The IETF ROLL working group has standardized the RPL routing protocol, i.e. the distributed algorithm which finds the multi-hop path connecting the nodes in the network with a small number of destination nodes.

These standards can be layered one on top of another, forming the following protocol stack:

application

CoAP, HTTP

transport

UDP, TCP

IP/routing

IETF RPL

adaptation

IETF 6LoWPAN

medium access

IEEE802.15.4e

phy

IEEE802.15.4-2006

logo_google.jpgThe OpenWSN team is happy to announce is it recipient of the 2016 Google IoT Technology Research Award http://googleresearch.blogspot.fr/2016/02/announcing-google-internet-of-things.html! The research focuses on how IEEE802.15.4 and WiFi coexist, and how 6TiSCH and IEEE802.15.4e Time Synchronized Channel Hopping can be used to simplify coexistence between the two. This research includes porting the OpenWSN protocol stack (which implements IEEE802.15.4e TSCH, 6TiSCH, 6LoWPAN, RPL,…

  1. The project is so excellent!  It is better than any book or paper to study WSN.

  2. where can i find more documentation i really need to learn about it and how to work with it ...

  3. thabetrihab, for the openwsn project, we use this site : (https://openwsn.atlassian.net/wiki) as the documentation. So basically you can find all related information here.

    For kickstart: you can visit Get Started, choose the OS environment you are using, you will find out how to install everything openwsn dependency. (also it has a tutorial how to build a network with openwsn)

    For the stack openwsn is implementing, it's located here: Protocol Stack

    The OpenVisualizer is used for monitoring the status of network and communicate with the mote.

    You can also look around to see more information about openwsn.
