What is Xwire Linux?

Xwire Linux is a wireless mesh enabled router flash based firmware which contains features that allow you to build your network easily and quickly.

The firmware is available for the most common industry standard embedded platforms and offers a common operating environment to managing all your network hardware platforms.

Xwire Linux uses open standards, open source, and Linux to create an easy to use wireless operating environment to create network connected applications. Xwire Linux is available for download and can be used on any standard Compact Flash. Installation is simple and the requirements are minimal.

Appendix B - Planning and Designing The Network

Channel Planning

Deploying a network requires careful channel planning.

 

ISM Band Description

 

There at most three non-overlapping non-interfering channels in the 2.4Ghz band.

Working from the Console or Shell

 

System Configuration

sysconfig is single data store configuration and interface program to manipulate the data store.

A simple and consistent interface was developed for the UI interface without having to develop a different parsing method for each system configuration file. The system configuration uses templates to substitutes the configurable variables to produce the resulting configuration file used by the processes and system services.

This allows system script could interface to the data store in a consistent way and attempts to keep configuration of command line users and GUI users in sync.

OLSR Configuration

This screen provides feedback about how OLSR is currently configured.

 

OLSR Routes

This screen is used to understand how OLSR routies are formed between routers and border routers.

 

OLSR Topology

This screen provides insight into OLSR metrics, links, and neighbors that form the network topology. 

 

Appendix A - Performance Testing

Scope
The scope of these tests are to evaluate stability and performance of Linux, driver, and wireless network interfaces using various network configurations to achieve optimal performance. These tests do not account for interoperability and compatibility of various wireless NICi manufactures.

Description
The following is a description of the test tools, test cases, configurations, and assumptions to perform performance testing of the target system. This document is accompanied by diagrams detailing the test case configurations.

Managing the Xwire Router

There are two ways to configure the access pointi: via ssh and serial ports. To configure via ssh, see the default configuration above for information about which IPi addresses to use, what interfaces are available, and what to expect.

Accessing using ssh connection

With an ssh client, the Xwire Router can be accessed at any one of the interfaces. However, because the sshd daemon and networking does not start until after the Xwire Router is fully operational, many of the log messages that are visible under serial connections are not available. These can be examined via the dmesg command line. The only requirement to make ssh connections is a wireless or wired network adapteri card that has a route to the Xwire Router and a ssh client.
