IPv6 Label Switching on IEEE 802.15.4

2009 Third International Conference on Sensor Technologies and Applications, 2009
Driven by the idea to converge to the Internet of Things, we searched within the course of a FP6-project for a suitable mechanism to transport IP packets on ad-hoc wireless personal area networks (WPANs). Prior work was already done and so we decided to start with RFC4944, which was probably the best working solutions for this problem.

Towards an IEEE 802.15.4 SDR transceiver

2010 17th IEEE International Conference on Electronics, Circuits and Systems, 2010
One of the goals of a software defined radio system is to be adaptable to send and receive data according to several specifications. That can be achieved if that system implements most of the communication operations, including physical layer tasks, in reconfigurable platforms.

Evaluating IEEE 802.15.4 for CPS

2015
This chapter provides a brief introduction of IEEE 802.15.4 and its compatibility toward CPS. IEEE 802.15.4 was not designed for networks that provide guaranteed QoS, while the performance of cyber-physical applications usually depends highly on QoS of the underlying networks. Therefore, it becomes necessary and important to assess the applicability of

IEEE 802.15.4 Based Adaptive MAC Protocols

2015
WSANs provide the infrastructure for many applications of CPS. Lots of these applications use the IEEE 802.15.4 standard. However, it does not provide any means of differentiated services to improve QoS for time-critical and delay-sensitive events. A large amount of efforts have been made to address such issues.

IEEE 802.15.4 security sublayer for OMNET++

2017 13th International Wireless Communications and Mobile Computing Conference (IWCMC), 2017
Most network simulators do not support security features. In this paper, we introduce a new security module for OMNET++ that implements the IEEE 802.15.4 security suite. This module, developed using the C++ language, can simulate all devices and sensors that implement the IEEE 802.15.4 standard. The OMNET++ security module is also evaluated in terms of

Comparative Analysis of IEEE 802.15.4 and IEEE 802.15.6 Standards

2014 International Conference on Computational Intelligence and Communication Networks, 2014
A Wireless Personal Area Network is a network of interconnecting devices centered around an individual's work space. Wireless Sensor Networks as well as Body Area Networks can be used in a Wireless Personal Area Network. The IEEE 802.15 group is specifically concentrated on the standardization of the Wireless Personal Area Networks and also categorizes

IEEE 802.15.4 Compliant RF Module Design

2005 IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications, 2006
The RF module is designed using the CC2420 IC and ATmega128 MCU. The RF module, which is few in power consumer and small in size, works at the frequency of 2.4 GHz and is IEEE 802.15.4 compliant, and can be used widely in low-data-rate communications.

Interference Mitigation in IEEE 802.15.4 Networks

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
In this paper, we consider interference mitigation in IEEE 802.15.4 beacon-enabled cluster-tree networks. The proposed scheme first detects the presence of interference by means of packet-error detection and/or channel sensing in a clusterwise manner.

Proximity Sensing Using IEEE 802.15.4 Radios

2006
Accurately determining the location of devices is a key challenge in contextual smart sensing. This poster describes how IEEE 802.15.4 radios can be used for accurate proximity sensing of co-located devices. In particular, the effect of low noise amplifiers on the estimation accuracy are discussed.
