le-warp / University of Oulu
Le-WARP environment is based on Wireless open Access Research Platform (WARP) developed by Rice University (http://warpproject.org). WARP is well suited for wireless research on both physical (PHY) and medium access control (MAC) layers but it lacks the capability of handling network layer. That is why we decided to create Linux enriched WARP (Le-WARP), which implements fully functional network layer on the board. Our Le-WARP design is using WLAN based reference design, which is operating on 2.4 or 5 GHz bands.
We introduce two processor core design for running Linux OS on the board, whereas reference design is using one processor core for running MAC code. The new design makes the platform more independent part of the research network, it adds the capability of running network layer functions on board, such as routing and applications for monitoring and measuring the traffic of the network.
On top of link level research, routing capabilities makes it possible to create various networks with our environment, emulated cellular networks and Ad Hoc networks have been created in previous projects.

SRE can be used for:
Emulating mobile networks
Building Ad Hoc networks
Testing and prototyping different PHY and MAC layer functionalities in real-time environment
currently 5 pieces of WARP v3 (newest) and 9 pieces of WARP v2
Le-WARP software design for both versions of the platform
graphical user interface (GUI) to illustrate network behavior
experts for using and modifying current system
all necessary tools for programming the devices and measurement tools
Visible Light Communication (VLC) capability is under development, it will enable use of hybrid systems where both RF and optical links are used for communication.
WARP environment have been used to demonstrate many novel concepts of wireless communications, to mention few:
1) Centralized network emulating mobile networks which contain base stations (BSs) and user equipments (UEs)
Co-primary Spectrum Sharing with Inter-Operator D2D Trial, presented in MobiCom 2014,
Benefits Of Cooperative Offloading In Cognitive Radio Networks, FRUCT Conference 2012
2) Cognitive Radio Assisted Mobile Ad Hoc Network (CRAMNET)
In MobiCom 2010 Chicago, Best Demonstration Award
On Monday 11 January 2010 the first phone call over a cognitive radio network using CRAMNET
3) Distributed TDMA MAC Protocol Implementation with OLSR on Linux Enriched WARP for Ad hoc networks
In MobiCom 2009 Beijing, Best Demonstration Award
Development of Le-WARP environment has been funded by many internally and externally funded projects during last 7 years. Development of Le-WARP system is currently part of the WNL project, which includes also modular Wireless Sensor Network (mWSAN) environment. WNL project contains research of both environments, but in future research project Le-WARP and mWSAN environments can be exploited together or separately. Separate SRE description about mWSAN environment is available.
