Scheduling for interference mitigation using enhanced intercell interference ...eSAT Journals
Abstract Deployment of low power base station (pico) in macro cell is a key for providing high data rates. Cell range expansion is one of the features of LTE-advanced where low power base station in a heterogeneous network can increase their coverage area and neighboring cells can offload users to low power base station to reduce overload in macro cell. This presents a very challenging multi-user communication problem. Co-channel deployed Het-Net will experience interference between pico and macro. The main challenge of pico cells embedded into a macro cell is to let more users profit from the additional bandwidth introduced into the network. Enhanced Inter-cell Interference Coordination (eICIC) has been introduced to solve interference problem. Scheduling for eICIC is used to provide best solution for interference mitigation, overload in macro cell, fairness in resource usage by users. In this paper we have analyzed Round Robin scheduling for eICIC, results prove that fairness is maintained between users and throughput has been improved. Key Words: LTE - Long term Evolution, UE - User Equipment, eNB – eNodeB.

EFFECT OF HASH FUNCTION ON PERFORMANCE OF LOW POWER WAKE UP RECEIVER FOR WIRE...IJNSA Journal
Next generation network will consist of different types of wireless networks like WSN, Wi-Fi, WiMAX, UMTS, LTE and etc. Wireless Sensor Network (WSN) finds unique and special application as compared to the said networks because sensors are deployed in a very secret, awkward and hostile environment like battle field etc. Various wireless sensor nodes are interconnected and form a Wireless Sensor Network. Sensor nodes once deployed in a region, can’t be repaired thus the power system deployed in the nodes becomes a major key issue i.e. how long its battery life can be utilised. Another major issue of WSN is to have a more secured network which is a function of hash keys. Increase usage of hash key means enhanced security but at the cost of power and area. Sensor systems must utilize the minimal possible energy while operating over secured and wide range of operating scenarios. In this paper, we have proposed a novel ID matching mechanism that uses a Bloom filter to realize wake-up wireless communication. Paper uses hash function for uniquely recognizing particular sensor- node- cluster among all clusters. Paper also shows the effect of number of hash functions on performance of wireless sensor node. The design and implementation of a wireless wake-up receiver module simulation reveals
that proposed model consume 724nW dynamic power and with bloom filter, the proposed model consumes dynamic power 85% less than the consumption cited in “Takiguchi” model[1]. Dynamic power is further reduced by 10% when parallel processing is implemented. Finally paper provides a novel approach to save the dynamic power and subsequently increases the battery life of wireless sensor node and network as a whole.

A wireless sensor network has important applications such as remote environmental monitoring and target tracking, particularly in recent years with the help of sensors that are smaller, cheaper, and intelligent. Sensors are equipped with wireless interfaces with which they can communicate with one another to form a network. A WSN consists of a number of sensor nodes (few tens to thousands) working together to monitor a region to obtain data about the environment. The design of a WSN depends significantly on the application, and it must consider factors such as the environment, the applications design objectives, cost, hardware, and system constraints.
Current Activities in WSN: Developing test bed for target tracking Using Passive Infrared and Ultrasonic Sensors Improving the delivery rate in low power wireless networks .Guided Navigation of Friendly Vehicle towards tracked Object. Design and development of smart mines and explosive ordinance for intelligent activation and deactivation and safe recovery based on secure WSN. Design of a data mule for data collection from remotely placed sensor nodes
The course gives the thorough concepts of the wireless sensor networks, applications examples. It also gives detailed study of sensor node architecture and various protocols used in wireless sensor networks. It also covers issues related to topology, clustering ,synchronization and operating execution environment used for wireless sensor networks.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Abstract
Surveillance is a key aspect in security scenario in existing world. The existing systems consist of continuous monitoring and
recording of the scenario or area under surveillance. This causes considerable amount of power expense and unnecessary data
recording. To counteract these two problems we propose here a system which has an energy harvester and intelligent power saving
technique. The proposed system consists of an PIR and a proximity sensor placed in the line of sight of the camera. When any kind of
anomaly is detected in the foreground of the camera, the camera is powered on by the energy harvester unit to turn on the camera.
Once the foreground is cleared of the anomaly the energy harvester unit stops the power to the camera and shut down the camera.
This helps in significant improvement in power saving and longer battery life in wireless sensor network. The image process
techniques use the background subtraction to detect the geometry of anomaly. The proposed method also has renewable energy
production system with a solar panel and a energy management unit for charging and discharging unit. The total system will have
codes written in MATLAB for the blob analysis of image acquired. The frames will be analyzed by MATLAB for same. The proposed
system offers significant improvement in power saving in image acquisition.
Keywords: surveillance, infrared sensor, anomaly, wireless sensor network, energy harvester, power saving technique

1. INTRODUCTION
The focus of surveillance missions is to acquire and verify in-
formation about enemy capabilities and positions of hostile
targets. Such missions often involve a high element of risk for
human personnel and require a high degree of stealthiest.
Hence, the ability to deploy unmanned surveillance missions,
by using wireless sensor networks, is of great practical
importance for the military. Because of the energy constraints
of sensor devices, such systems necessitate energy aware
design to ensure the longevity of surveillance emissions.
Solutions proposed recently for this type of system show
promising result. However, the simplified assumptions they
make about the system in the simulator often do not hold well
in practice and energy consumption is narrowly accounted for
within a single protocol. One of the key advantages of
wireless
Sensor networks (WSN) is their ability to bridge the gap
between the physical and logical worlds, by gathering certain
useful information from the physical world and
communicating that Information to more powerful logical
devices. If the ability of the WSN is suitably harnessed, it is
envisioned that WSNs can reduce or eliminate the need for
human involvement in information gathering in certain
civilian and military applications. In the near future, sensor
devices will be produced in large quantities at a very low cost
and densely deployed to improve robustness and reliability.
They can be miniaturized into a cubic millimeter package in
order to be stealthy in a hostile environment. Cost and size
considerations imply that the resources available to individual
nodes are severely limited that limited processor band width
hand memory are temporary constraints in sensor networks.
They will disappear with fast developing fabrication
techniques. The energy constraints on the other hand are more
fundamental. According to R.A. Powers battery capacity only
doubles in 35 years. Energy constraints are unlikely to be
solved in the near future with the slow progress in battery
capacity and energy scavenging. Moreover, the untended
nature of sensor nodes and the hazardous sensing
environment preclude manual battery replacement. For these
reasons, energy awareness becomes the key research
challenge for sensor network protocol design.
2. RELATED WORK
A video sensor node in a wide area sensor network is a node
capable of performing on-board video processing, and com-
municating the information over a self-organizing and fault-
tolerant wireless network. Commercial CCTV and PC-based
surveillance systems are not suitable for wireless sensor net-

work surveillance application, and are orthogonal to our
approach. In fact, the CCTV are not processing the data on
line and are wired for power consumption, while PC-based
and com mercial cameras rely on high power consumption,
which is not suitable for the WSN. For this reason, this
section does not re- view these kinds of solutions.
Recently, several platforms and commercial cameras with
similar goals have been developed within a sensor.
We can classify these approaches in three categories:
• Lowcost nodes with wired interface (e.g., commercial
USB/LAN camera, or the node designed by
Corely[12];
• Wireless nodes with significant power consumption
• Application-specific single ultra-low power single chip
solution
Being wired, the nodes in the first category obviously do not
satisfy the basic requirement of being wireless, thus usually
these cameras send the data to a remote host to be processed,
although novel commercial cameras have the possibility to do
it on-board they still send the results by means of a wire.
Instead, nodes in the second category consume roughly more
power than a typical first generation wireless sensor node and
for this reason they are not suitable for wireless sensor
network which should work for several months. Finally,
single-chip solutions have extremely low-power consumption,
but they are neither programmable nor configurable in field.
One important common point among current video wireless
nodes belonging to the first and second category is that the
digital signal processing sub- system is the main power
bottleneck. This is due to the fact that the high data rate of
CMOS image sensor imposes the selection of fast processors
and memories with high power consumption. Hence, the main
open challenge in this area is to synergistically develop
algorithms and architectures for energy-efficient image
processing without giving up the flexibility of in-field
configuration.
The academic literature provides more similar approaches in
terms of low-power cameras and wireless sensor application.
In sensor nodes equipped with PIR, acoustic and magnetic
sensors have been deployed in order to achieve adjustable
sensitivity, stealthiness and effectiveness in a distributed
military surveillance applications. To balance privacy and
security in surveillance applications, networks of infrared
sensors (IR) and cameras are employed also in. Cameras are
used in public areas while networks of IR detectors [14]are
deployed in private areas. The system processes the data from
IR sensors in order to detect an event of interest in the private
area to identify the author by correlation with the images
grabbed in the public area. Energy conservation through
limiting the sensing to a small part of the network was also
considered in. In, the activation pattern is swept across the
network. Both schemes assume a simple topology and do not
handle sensing holes due to the sleeping time of the sensors.
In fact in this previous work the sleeping time is fixed and the
sensor could sleep also when it is need have data acquisition.
In, the activation pattern follows a user-defined path through
the sensor network as a sentry. In, a sleep/wakeup strategy in
solar-powered wireless sensor is presented. Our work
incorporates many similar ideas to the ones mentioned above
however in contrast to the other works we present a
combination of video sensor with other low-cost and low-
level sensors, which are used mainly for triggering the camera
at the right time and not to promote a reduction of the system
energy requirements. In fact the PIR sensor can be used as an
ultra low power wake-up trigger to re- duce the power
consumption when the video processing is not needed.
Moreover, data from PIR sensors can be used from the
application to understand when the best moment for starting
an image acquisition occurs. This will bring both a reduction
of false positives and a reduction of the number of frame
being processed, thus also a reduction of power consumption.
Finally, we equipped the node with a solar panel to recharge
the batteries and achieve perpetual work.
3. SYSTEM ARCHITECTURE
Fig 1 Camera sensor with PIR sensor, processing unit
ATMEGA 328 microcontroller with SRAM
Fig. 1 shows the smart camera structure. A smart camera is a
camera that can do on-board processing instead of
transmitting all video data to a central controller. The choice
of a smart camera is motivated by the notably reduced power
consumption required by processing on-board compared to a
solution relying on transmitting raw data through a wireless
interface. The wire- less smart camera consists of a camera
sensor, an embedded processor (Atmega328 from STM), a
CMOS video sensor (VS6624 from STM), a pyroelectric
infrared sensor used as trigger and a wireless communication
module, being supported through a suitable interface which
can host either a ZigBee or Bluetooth compliant transceiver.
The whole system is designed to achieve low power
consumption. Each device provides a power saving mode to
reduce consumption when not in use. The smart camera is
connected to a host (central PC) to send alarms or relevant

image content; moreover it can receive wireless messages
from the host so as to modify its settings was very easy to
implement .the transformation is made by using Zigbee or
other latest technology.
3.1. Processing Core
Choosing the suitable target hardware for a smart camera
processor is an important issue. Due to the very large amount
of data involved in image processing and computer vision
tasks and the aforementioned constraints on power
consumption, we have chosen The high-performance Atmel
8-bitAVRRISC-based micro controller combines 32 KB ISP
flash memory with read-while-write capabilities, 1 KB
EEPROM, 2 KB SRAM, 23 general purpose I/O lines, 32
general purpose working registers, three flexible
timer/counters with compare modes, internal and external
interrupts, serial programmable [21]USART, a byte-oriented
2-wire serial interface, SPI serial port, 6-channel 10-bit A/D
converter (8-channels in TQFP and QFN/MLF packages),
programmable watchdog timer with internal oscillator, and
five software selectable power saving modes. The device
operates between 1.8-5.5 volts. By executing powerful
instructions in a single clock cycle, the device achieves
throughputs approaching 1 MIPS per MHz, balancing power
consumption.
3.2. CMOS Image Sensor
To achieve low power consumption we chose the VS6624
CMOS imager from STMicroelectronics as the video device.
The image sensor provides full SXGA (1280 1024)
resolution at 15 frames per second, or VGA (640 480)
resolution at 30 frames per second. A very important feature
is the power consumption, which is just 120 mW when active
(2.8 V and 12 MHz frequency), while it goes down to 23 mW
when it switches to standby. The CMOS camera can be
programmed and controlled via internal registers using I C
serial interface. It supports several output formats, however
most video processing algorithms use grayscale image, thus
we adopt 8-bit grayscale images with YCbCr 4:0:0 formats.
Although it supports SXGA resolution, due to limited size of
the internal SRAM only little parts of the images can be
processed, typically 160 120 pixels, but the node can use
external RAM extending the memory capability. This
resolution is enough to perform our image processing
algorithm, and to save time and energy for storing and
processing data.
3.3. Pyroelectric Infrared Senor
Pyroelectric devices, such as the PIR sensor, have +ve
elements made of a crystalline material that generates an
electric charge when exposed to infrared radiation. The
changes in the amount of infrared striking the element change
the voltages generated, which are measured by an on-board
amplifier. The device contains a special filter called a Fresnel
lens, which focuses the infrared signals onto the element. As
the ambient infrared signals change rapidly, the on-board
amplifier trips the output to indicate motion.[17]

3.4. Wireless Transceiver
Analog wireless is the transmission of audio and video signals
using radio frequencies. Typically, analog wireless has a
transmission range of around 300 feet (91 meters) in open
space; walls, doors, and furniture will reduce this range.
Analog wireless is found in three frequencies: 900 MHz, 2.4
GHz, and 5.8 GHz. Currently, the majority of wireless
security cameras operate on the 2.4 GHz frequency.
Most household routers, cordless phones, video game
controllers, and microwaves operate on the 2.4 GHz
frequency and may cause interference with your wireless
security camera. 900 MHz is known as Wi-Fi Friendly
because it will not interfere with the Internet signal of your
wireless network. The advantage of transceiver is multiple
receivers per camera: the signal from one camera can be
picked up by any receiver; you can have multiple receivers in
various locations to create your wireless surveillance
network.
3.5. Energy Harvesting Unit
Solar power is the conversion of sunlight into electricity,
either directly using photo voltaics (PV), or indirectly using
concentrated solar power (CSP). Concentrated solar power
systems use lenses or mirrors and tracking systems to focus a
large area of sunlight into a small beam. Photo voltaics

convert light into electric current using the photoelectric
effect. Photo voltaics were initially, and still are, used to
power small and medium-sized applications, from the
calculator powered by a single solar cell to off-grid homes
powered by a photovoltaic array. They are an important and
relatively inexpensive source of electrical energy where grid
power is inconvenient, unreasonably expensive to connect, or
simply unavailable.
A charge controller, charge regulator or battery regulator
limits the rate at which electric current is added to or drawn
from electric batteries. It prevents overcharging and may
prevent against overvoltage, which can reduce battery
performance or lifespan, and may pose a safety risk. It may
also prevent completely draining ("deep discharging") a
battery, or perform controlled discharges, depending on the
battery technology, to protect battery life. The terms "charge
controller" or "charge regulator" may refer to either a stand-
alone device, or to control circuitry integrated within a battery
pack, battery-powered device, or battery recharger. Charge
controllers are sold to consumers as separate devices, often in
conjunction with solar or wind power generators, for uses
such as RV, boat, and off-the-grid home battery storage
systems In solar applications, charge controllers may also be
called solar regulators. Some charge controllers/solar
regulators have additional features, such as a low voltage
disconnects, a separate circuit which powers down the load
when the batteries become overly discharged.
Lithium-ion batteries are common in consumer electronics.
They are one of the most popular types of rechargeable
battery for portable electronics, with one of the best energy
densities, no memory effect and only a slow loss of charge
when not in use. Beyond consumer electronics, LIBs are also
growing in popularity for military, electric vehicle and
aerospace applications. Handheld electronics mostly use LIBs
based on lithium cobalt oxide (LiCoO2), which offers high
energy density, but presents safety risks, especially when
damaged.

4. VIDEO ANALYSIS ALGORITHM
In the field of computer vision, blob detection refers to
mathematical methods that are aimed at detecting regions in a
digital image that differ in properties, such as brightness or
color, compared to areas surrounding those regions. There are
two main classes of blob detectors: (i) differential methods
are based on derivatives of the function with respect to
position, and (ii) methods based on local extreme are based
on finding the local maxima and minima of the function.
Another common use of blob descriptors is as main primitives
for texture analysis and texture recognition.[23]
The contours of an object in an image are determined by
calculating the gradient magnitude of each pixel in the image.
The stronger the intensity transition, the greater the
magnitude will be. The gradient magnitude is calculated at
each pixel position from the image's first derivatives. It is
defined as:
Gradiant magnitude =
Where: ׀x and ׀y = the X and Y derivative values, respectively
They define the components of the gradient vector as:
Gradiant vector =
An edge element (edge) is located at the maximum value of
the gradient magnitude over adjacent pixels in the direction
defined by the gradient vector. The gradient direction is the
direction of the steepest ascent at an edge in the image while
the gradient magnitude is the steepness of that ascent.[6][7].
The gradient direction also is perpendicular to the object
contour. Well-defined contours are extracted from strong and
sharp intensity transitions. A strong contrast between the
objects and their background improves the edge detector's
robustness and location accuracy.

5. EXPERIMENTAL RESULT
5.1. Video Analysis Evaluation
Experiment concerns an indoor setup aimed at monitoring a
sector of a hallway in a building. The camera was placed a
few meters away from the wall and switched on. In order to
achieve the best performance, the camera has to be firmly
attached to the wall or placed over a vibration-free surface
[24]. In fact, although the camera is mounted on a mobile
device, the image processing algorithm assumes the presence
of a static camera. Meanwhile several real
abandoned/removed object instances were generated. The
processed images were sent directly to a host PC via
Bluetooth. We have analyzed three continuous footages
where, each time the camera was switched on by the PIR
sensor, the cur- rent frame was processed by the proposed
algorithm. We have collected a total of 64 frames, with each
frame containing at times even multiple abandoned/removed
objects, for a total of 78 abandoned/removed objects. Also, a
subset of frames does not contain any case of object
removal/abandon. As for the background subtraction
algorithm, out of 78 ROIs, 77 ROIs have been correctly
detected by the algorithm, yielding only one false negative
and four false positives, for a correct segmentation rate of
98.7%. These 77 ROIs, fed to the classification stage, were
then correctly classified in 73 cases as abandoned/removed
object, yielding to a correct classification rate of 94.8%.
Fig.5 reports some qualitative examples of correct
segmentation and classification yielded by the proposed
algorithm on the dataset of Experiment 1. In the figure, seven
examples are reported (indicated by letters a–f), where for
each example the two frames and the final output of the
algorithm are shown. As for the output, each detected ROI is
indicated by a white bounding box, while the classification
result is encoded as a symbol shown inside each detected
bounding box: the ― ‖ symbol stands for abandoned object
(as if it is added to the scene) while the ― ‖ symbol stands for
removed object (as if it is subtracted from the scene). As it
can be seen from the figure, the proposed algorithm is able to
achieve correct segmentation and classification also in
presence of very small, partially trans- parent objects (cases e
and f) and with multiple ROIs (cases a-f).
In Experiment 2, we present a qualitative evaluation of the
proposed algorithm in an outdoor environment under sunny
conditions, which concerns specifically the case of
monitoring a wall from undesired events such as graffiti,
stealing or unauthorized poststicking. In this case the distance
from the wall was around 5 m in the case (a–c) Figs.6 m in
(d) our system has been tested against events such as graffiti
(case a), wall affixtures (case b), object removal [case c and
Fig. 10(d)]. Finally a situation where only illumination
changes occur in the scene is shown in Fig. 9(d) In this test
the camera was left at 1000 in morning and the video
processing were performed 2 h later with different light. As it
can be seen, our algorithm is capable of robustly handling all
the aforementioned cases, yielding correct classification also
when the object ROI is particularly small (e.g., case c of both
figures and d Fig. 10, and with each single writings appearing
in the graffiti situation concerning case a) and despite the
nonoptimal illumination conditions.

object removal (c), illumination change (d).
5.2. Power Consumption Analysis
Table IV shows the power consumption of our prototype. The
table shows how the power consumption of the whole system
in sleep mode is more than 10 times less than that in normal
mode. We estimated that the average time to elaborate one
abandoned/ removed object event is about 3 s from the
moment when the detection starts. Moreover, the amount of
time required for blob analysis depends on the number and
size of the detected ROIs. Hence, it will be zero if the system
does not detect any blob and about 100 ms for three ROIs
sized 16 pixels. To evaluate the benefits provided by our
approach in terms of improvement of battery life we consider
the same system without PIR sensor. More specifically, we
com- pare the two approaches assuming different amounts of
random events (i.e., 50, 100, 300 events per hour) and by
estimating the lifetime of the three scenarios using a full 2000
mAh bat- tery. In the first simulation the PIR sensor is
disconnected and the system does not know when to switch
off/on the camera or when to turn into sleep mode, so it will
work continuously and the power consumption will be
independent from the number of events. Then, in our
approach, and as previously mentioned, the PIR sensor
detects events and wakes up the microcontroller which waits
until the FOV is empty to start the video analysis. When the
video analysis is over the microcontroller turns the camera off
to reduce power consumption.
Table -3: Power consumption of the video sensor node
Using the solar panel to harvest the energy, we can obtain an
additional improvement of battery life, achieving perpetual
working in an application scenario with 50 events per hour. A
simulation verifying the performance of the proposed system
is depicted in Fig. 7, where the energy harnessed from the
solar cell powers the sensor node and recharges the battery
with the exceeding events. In our simulations we assume a
rate of 50 events per hour representing people walking within
the field of view of the video node. Furthermore we measured
the energy intake from the energy harvester and the solar light
intensity during five days (Fig.8). All the information was
stored in files used as input to our simulations. Finally the
energy level of the battery at the beginning of the simulation
is half its full capacity (2000 mAh, expressed in Joules). This
simulation shows how the system can work perpetually with a
small PV panel. The node without the energy harvester stops
working after approximately 40 h, as it can be seen from Fig.
7. Instead, the node with the harvester can recharge its battery
during the day, the energy accumulated in the battery being
sufficient to keep the node on during the night.

6. COCLUSIONS
Proposed method utilizes the efficient energy harvesting
methodology for increasing the charged battery life. The
Codes written in the Arduino board helps in significant
controlled discharge of battery during the surveillance and
efficient charging from environment. The use of MATLAB
subsequently gives a better environment for image processing
and blob analysis. The present algorithm can be enhanced by
smart optimization techniques. In this work, a self-powered
wireless smart camera for run time video processing has been
presented. The proposed approach have shown that combing
advanced hardware/software solutions makes possible high
accuracy and perpetual work in video processing on wireless
sensor network where smart cam- eras find the most critical
constrain in the power consumption.
In fact, energy harvesters provide energy to replenish the
batteries, while the combined use of different sensors with
heterogeneous features allows for a remarkable reduction of
the overall power consumption. We designed the camera for
real time video processing algorithm and an ad-hoc
abandoned/re- moved object using PIR features. Data were
presented to evaluate the performance of our approach in term
of energy consumption, video processing application and
accuracy. The experimental results showed the versatility of
the application in indoor and outdoor scenario and the
simulation showed the perpetual work was achieved in
simulation outdoor scenario. Future work will include a
complete campaign of new experiments in order to analyze
better the issue of background changes and more challenging
condition (i.e., direct sun light, shadows). Moreover they will
be directed towards improving the hardware of the smart
camera node, video processing algorithm, and distributed
intelligence.
