The Collection Tree Protocol for the Castalia Wireless Sensor Networks Simulator

The Collection Tree Protocol (CTP) is a well-know protocol that provides a reliable collection service for wireless sensor networks. In this report, we describe our implementation of CTP for the version 3.0 of the Castalia wireless sensor networks simulator. Besides being a reference for researchers interested in experimenting with CTP in Castalia, this report also provides a throughout description of the mechanisms of CTP. As the structure of our Castalia-based implementation mimics that of CTP’s TinyOS 2.1 components, the report also offers several insights into the details of such components. A former implementation of CTP for Castalia 1.3, which we had described in previous work [8], is no longer supported. The module implementing CTP for Castalia 3.0 is publicly available at http://code.google.com/p/ctp-castalia.
