COMPARATIVE ANALYSIS OF VARIABLES USED IN ZIGBEE DISTRIBUTED NETWORKS FOR INTRUSION DETECTION ON END DEVICES IN AN UNMANNED AUTONOMOUS VEHICLES NETWORK

Cyber attacks have become more common and sophisticated in the new age of technology. Intrusion detection systems were designed to detect attacks while they are being carried out and many applications have been deployed in IoT, showing great effectiveness to identify anomalies. However, almost all of them are built under a conventional scheme where network traffic is generated by services based on a client-server architecture. Pure Zigbee networks are distinguished by the connection between end devices and do not generate this kind of network traffic because Zigbee protocol stack is limited. Because of this, many of the variables presented in related works to train machine learning algorithms are not present in such a network. This would generate effects such as data theft, identity theft, permanent loss of information and even manipulation of devices, something significantly serious in the area of unmanned vehicles. The purpose of this article is to expose variables obtained from pure Zigbee in a distributed environment can be used to identify intrusions in a simulated test case such as the connection between unmanned vehicles. In this way, a new identification approach is introduced, within end devices are focused instead network traffic only to identify anomalies. It is intended to demonstrate that CPU and RAM variables analysis directly from end devices allow an effective identification in packet storm denial of service attacks and that they would be a considerable option to avoid end effects.

Design and Measurement of a Differential Printed Antenna for a Wireless Sensor Network Node

This letter presents the design and measurement of an antenna integrated into an agricultural sensor network node operating on the 2.4-GHz ISM band using the ZigBee protocol stack. The novel structure, coined bowtie-shaped folded dipole (BSFD) , has a differential 100- $\Omega$ input impedance matching a particular controller widely used in wireless sensor network (WSN) applications. This letter also presents a survey of existing WSN antennas to which the proposed design compares favorably. The challenges of testing a differential antenna using conventional single-ended equipment are addressed regarding antenna impedance and radiation pattern measurements. The differential antenna input impedance was confirmed with four different test setups using a conventional vector network analyzer. The radiation pattern of the proposed antenna was measured in-prototype resorting to a spectrum analyzer. The measured patterns show that the proposed antenna has a maximum received power over 4 dB compared to two early versions of the WSN node that used commercial off-the-shelf antenna solutions. The performance was also confirmed in a field test where a BSFD-equipped prototype achieved close to a 300-m range, tripling that typical for ZigBee applications.

Device and operation mechanism for non-beacon IEEE802.15.4/Zigbee nodes running on harvested energy

The power supply is one of the main constraints when operating Wireless Sensor Networks (WSN). The most obvious energy source for a WSN node is a rechargeable or non-rechargeable battery. Batteries seriously limit WSNs usage and are associated to the increasing cost of large networks. Low cost networks will be achieved when battery consumption becomes substantially reduced or eliminated. Within this scope, powering WSN devices using mains power, is not an advantage since node installation requires complex and time consuming actions. Replacing batteries is therefore an important topic even in environments with mains power availability. In this paper, a battery-less device running an IEEE802.15.4/Zigbee protocol stack on harvested energy is proposed. Its operation mechanism and required software adaptation to sustain this complex protocol are described. The protocol compliant node uses a contact-less scavenger system that is able to power a WSN node from mains power lines thus providing an inexpensive and easily installable device even for non-skilled users.

A holistic approach to ZigBee performance enhancement for home automation networks.

Wireless home automation networks are gaining importance for smart homes. In this ambit, ZigBee networks play an important role. The ZigBee specification defines a default set of protocol stack parameters and mechanisms that is further refined by the ZigBee Home Automation application profile. In a holistic approach, we analyze how the network performance is affected with the tuning of parameters and mechanisms across multiple layers of the ZigBee protocol stack and investigate possible performance gains by implementing and testing alternative settings. The evaluations are carried out in a testbed of 57 TelosB motes. The results show that considerable performance improvements can be achieved by using alternative protocol stack configurations. From these results, we derive two improved protocol stack configurations for ZigBee wireless home automation networks that are validated in various network scenarios. In our experiments, these improved configurations yield a relative packet delivery ratio increase of up to 33.6%, a delay decrease of up to 66.6% and an improvement of the energy efficiency for battery powered devices of up to 48.7%, obtainable without incurring any overhead to the network.
