Abstract
The IEEE 802.15.4 standard defines the PHY and MAC layer specifications for Low-Rate Wireless Personal Area Networks (LR-WPANs). With the proliferation of many time-critical applications with real-time delivery, low latency, and/or specific bandwidth requirements, Guaranteed Time Slots (GTS) are increasingly being used for reliable contention-free data transmission by nodes within beacon-enabled WPANs. To evaluate the performance of the 802.15.4 GTS management scheme, this paper introduces a new GTS simulation model for OMNeT++ / MiXiM. Our GTS model considers star-topology WPANs within the 2.4 GHz frequency band, and is in full conformance with the IEEE 802.15.4 – 2006 standard. To enable thorough investigation of the behaviors and impacts of different attacks against the 802.15.4 GTS mechanism, a new GTS attacks simulation model for OMNeT++ is also introduced in this paper. Our GTS attacks model is developed for OMNeT++ / NETA, and is integrated with our GTS model to provide a single inclusive OMNeT++ simulation model for both the GTS mechanism and all known-to-date attacks against it.
Highlights
The IEEE 802.15.4 standard defines the Physical (PHY) and Media Access Control (MAC) layer specifications for Low-Rate Wireless Personal Area Networks (LR-WPANs)
This paper presents a new IEEE 802.15.4 simulation model in OMNeT++ which integrates two models; a model for the 802.15.4 Guaranteed Time Slots (GTS) management scheme, and a model for the different GTS attack variants known to date
The code for our GTS attacks model was initially included within the same project folder, named netattacks, as the NETA framework, and the MiXiM project folder was added as a project reference to the netattacks project
Summary
The IEEE 802.15.4 standard defines the Physical (PHY) and Media Access Control (MAC) layer specifications for Low-Rate Wireless Personal Area Networks (LR-WPANs). OMNeT++ is a C++ object-oriented simulation library and framework primarily used for building network simulators This network simulation platform provides an extensible, modular, and component-based architecture for building modelling frameworks, enabling the modelling and simulation of a diverse range of networks, including sensor networks and wireless ad-hoc networks, to name a few (Note 1). To build our GTS attacks model, OMNeT++’s existing NETA framework is extended. Our IEEE 802.15.4 GTS simulation model is in full compliance with the IEEE 802.15.4 – 2006 standard (Note 3), and is developed by extending the existing MiXiM framework in OMNeT++
