In particular, we will show a prototype system of WSDL/TCP/IP over a low data rate 802.15.4 radio used in home automation. The Web-service interface makes it easy for multiple programmers to develop home-control applications using devices manufactured by different OEMs without learning new programming technologies. Our system also provides a uniform setup experience for users, enabling them to integrate multiple home devices into a single network. We also will d...

A munin plugin for monitoring active hosts in the LAN
2008-03-07 01:28:00
My laboratory uses NAT for Internet connection. There are four subnet 10.10.1.0/24 - 10.10.4.0/24. I want to monitor the active hosts in the LAN. So I write this plugin. It uses the fping to get alive hosts list and counts the number. if [ "$1" = "autoconf" ]; then ; echo "yes" ; exit 0 fi if [ "$1" = "config" ]; then ; echo 'graph_title alive hosts' ; echo 'graph_args --base 1000 -l 0' ; echo 'graph_vlabel alive hosts' echo 'graph_category network' echo 'graph_info This graph shows the active hosts in the JSI network.' echo 'first.label 10.10.1.x' echo 'second.label 10.10.2.x' echo 'three.label 10.10.3.x' &...

Building a development environment for Xbow Motes on Gentoo
2008-03-04 06:13:00
http://www.acet.reading.ac.uk/~mjeg/blog. php?p=1165509636 The quick start installer from Xbow is for Windows. I wanted to configure my Gentoo Linux box as a development environment for writing Mica applications. From looking at the Cygwin environment set up by the Windows installer I knew I needed the tinyos (tos) development packages and the nesC compiler. On Gentoo all tos stuff is masked as unstable so you can’t just emerge what you need. This is what I did to build the environment: root@covent src # emerge sys-devel/crossdev root@covent src # echo "PORTDIR_OVERLAY=/usr/local/portage& quot; >> /etc/make.conf root@covent src # mkdir /usr/local/portage root@covent src # crossdev --target avr The final tool is the program to upload applications to the mote. This is called uisp, unfortunately the default version in Gentoo (when I was doing this ‘uisp-20050207-r1?) does not understand how to correctly talk to the serial programming board we have (mib510).

Reading Environmental Sensor Network (RESN)
2008-03-04 06:01:00
http://www.acet.rdg.ac.uk/projects/resn/i ndex.php The RESN project was initiated in order explore and build up local expertise in a range of Wireless Sensor Network (WSN) technologies. A goal of the project is to gain a better practical understanding of the capabilities of both the available hardware and software environments for supporting a range of applications, in the first instance those for environmental monitoring. The RESN project is a collaborative project between Computer Science and Soil Science departments. Together a public demonstrator is being created to provide a permanent WSN presence on the University campus, with an Internet facing application to access the network and publicise the effort. The knowledge gained through this project will be used to support the rest of the University during the inevitable uptake of WSN technologies. This web site is used to publish the lessons learned and goals achieved by the RESN project. http://www.acet.rdg.ac.uk/projects/re...
