using DDS for wireless sensor networks

Hi,

How DDS can be used in embedded OS for WSN. In computer DDS service is running as service/deamon, but in WSN

this not efficient for memory luck. So, how can we integrate DDS into the  Tmote sensor for example!

 

Thanks.

Which concrete WSN operating system are you looking at?

For this kind of environment I would look into using RTI Connext DDS Micro Edition: http://www.rti.com/products/micro/index.html  this is a very small-footprint version of RTI DDS which is distributed in source code such that it can be built for a variety of target platforms, inclucing systems with minimal operating systems.

RTI Connext DDS Micro Edition supports only a subset of the features and QoS. But does support the main ones like reliability, time filtering, etc. 

A very nice thing about RTI Connext DDS Micro Edition is that it supports the same DDS API and it is also compatible on the wire (i.e. imprements the standard OMG DDS-RTPS Wire protocol). So you can run this on some of the nodes and a full DDS, including tools ans such on other nodes.
