The document presents a design for context-aware vertical handoff in heterogeneous wireless networks. It aims to optimize handoff decisions based on context information. The design includes a context management framework to efficiently collect and share context data between network nodes. It also requires a flexible execution platform to adapt handoff policies based on dynamic context. Simulation results show the proposed context-aware approach reduces the number of handoffs and dropping probability compared to other algorithms, with moderate increase in delay.

Improving service quality using Bayesian networksKiran Kaipa
This document discusses using Bayesian networks to improve service quality analysis for communication service providers. It describes how service quality parameters can have multi-dimensional sources and analyzing them can be complex. Bayesian networks provide a well-defined structure to represent relationships between service quality parameters. Two example use cases are described: network route selection and international roaming list prioritization. It provides details on how Bayesian networks can be used for service-specific network route selection to choose routes best suited for different service types like video based on historical performance data.

SECURE & FAULT TOLERANCE HANDOFF IN VANET USING SPECIAL MOBILE AGENTcscpconf
This document proposes a fault tolerant mobile agent based information retrieval system for handoffs in vehicular ad hoc networks (VANETs). Special mobile agents are dispatched from client vehicles to neighboring vehicles to retrieve information needed for seamless handoffs as the client vehicle moves. The system uses checkpointing and replication to increase reliability, storing copies of data at each visited node. A timestamp and threshold ensure data validity and prevent excessive resource usage. Authentication with digital signatures secures communication between agents and nodes. The proposed approach aims to provide reliable information retrieval to support fault tolerant handoffs in VANETs.

Managing microservices with Istio Service MeshRafik HARABI
Developing and managing hundreds (or maybe thousands) of microservices at scale is a challenge for both development and operations teams.
We have seen over the last years the appearance of new frameworks dedicated to deliver ‘Cloud Native’ applications by providing a set of (out of box) building blocks. Most of these frameworks integrate microservices concerns at the code level.
Recently, we have seen the emerging of a new pattern known as sidecar or proxy promoting to push all these common concerns outside of the business code and provides them on the edge by integrate a new layer to the underlying platform called Service Mesh.
Istio is one of the leading Service Mesh implementing sidecar pattern.
We will go during the presentation throw the core concepts behind Istio, the capabilities that provides to manage, secure and observe microservices and how it gives a new breath for both developers and operations.
The presentation will be guided by a sequence of demo exposing Istio capabilities.
Telco infrastructure investment model remains unaffected by Managed Services or Outsourcing, especially in the African markets. Wisdom is necessary to balance the investment outlay between Access and Core/Transport networks to achieve an optimal telecom outlay.
The document discusses Microsoft .NET Framework 3.x and the Windows Communication Foundation (WCF). It provides an overview of WCF, including its architecture, contracts, runtime, ABCs (address, binding, contract), endpoints, addressing, bindings, and fault tolerance capabilities.
One of the most complex challenges in realizing microservice architecture is not building the services themselves, but building and governing the communication between services. Most microservices developers have to take care of complex inter-service communication logic as part of their service development.
Service Mesh has emerged as a solution to overcome the challenges that we have in microservices communication. Since most of the inter-service communication requirements are quite generic across all microservices implementations, we can think about offloading all such tasks to a different layer, so that we can keep the service code independent.
This presentation will discuss the following:
1) Why we need a Service Mesh?
2) Fundamentals of Service Mesh
3) Introduction to Istio
4) What's new in Istio 1.0.
5) Seamless integration of Ballerina and Istio

It describes the 1xEV-DO network architecture and call flow, and covers different types of hard handoffs including intra-RNC, inter-RNC/intra-PDSN, inter-RNC/inter-PDSN, 1xEV-DO to 1xRTT, and 1xRTT to 1xEV-DO. For inter-network handoffs, the PPP session and IP address may be maintained using mobile IP, otherwise a new PPP session and IP address will be established.
A Novel Method for Prevention of Bandwidth Distributed Denial of Service AttacksIJERD Editor
Distributed Denial of Service (DDoS) Attacks became a massive threat to the Internet. Traditional
Architecture of internet is vulnerable to the attacks like DDoS. Attacker primarily acquire his army of Zombies,
then that army will be instructed by the Attacker that when to start an attack and on whom the attack should be
done. In this paper, different techniques which are used to perform DDoS Attacks, Tools that were used to
perform Attacks and Countermeasures in order to detect the attackers and eliminate the Bandwidth Distributed
Denial of Service attacks (B-DDoS) are reviewed. DDoS Attacks were done by using various Flooding
techniques which are used in DDoS attack.
The main purpose of this paper is to design an architecture which can reduce the Bandwidth
Distributed Denial of service Attack and make the victim site or server available for the normal users by
eliminating the zombie machines. Our Primary focus of this paper is to dispute how normal machines are
turning into zombies (Bots), how attack is been initiated, DDoS attack procedure and how an organization can
save their server from being a DDoS victim. In order to present this we implemented a simulated environment
with Cisco switches, Routers, Firewall, some virtual machines and some Attack tools to display a real DDoS
attack. By using Time scheduling, Resource Limiting, System log, Access Control List and some Modular
policy Framework we stopped the attack and identified the Attacker (Bot) machines
Hearing loss is one of the most common human impairments. It is estimated that by year 2015 more
than 700 million people will suffer mild deafness. Most can be helped by hearing aid devices depending on the
severity of their hearing loss. This paper describes the implementation and characterization details of a dual
channel transmitter front end (TFE) for digital hearing aid (DHA) applications that use novel micro
electromechanical- systems (MEMS) audio transducers and ultra-low power-scalable analog-to-digital
converters (ADCs), which enable a very-low form factor, energy-efficient implementation for next-generation
DHA. The contribution of the design is the implementation of the dual channel MEMS microphones and powerscalable
ADC system.

Influence of tensile behaviour of slab on the structural Behaviour of shear c...IJERD Editor
-A composite beam is composed of a steel beam and a slab connected by means of shear connectors
like studs installed on the top flange of the steel beam to form a structure behaving monolithically. This study
analyzes the effects of the tensile behavior of the slab on the structural behavior of the shear connection like slip
stiffness and maximum shear force in composite beams subjected to hogging moment. The results show that the
shear studs located in the crack-concentration zones due to large hogging moments sustain significantly smaller
shear force and slip stiffness than the other zones. Moreover, the reduction of the slip stiffness in the shear
connection appears also to be closely related to the change in the tensile strain of rebar according to the increase
of the load. Further experimental and analytical studies shall be conducted considering variables such as the
reinforcement ratio and the arrangement of shear connectors to achieve efficient design of the shear connection
in composite beams subjected to hogging moment.
Gold prospecting using Remote Sensing ‘A case study of Sudan’IJERD Editor
Gold has been extracted from northeast Africa for more than 5000 years, and this may be the first
place where the metal was extracted. The Arabian-Nubian Shield (ANS) is an exposure of Precambrian
crystalline rocks on the flanks of the Red Sea. The crystalline rocks are mostly Neoproterozoic in age. ANS
includes the nations of Israel, Jordan. Egypt, Saudi Arabia, Sudan, Eritrea, Ethiopia, Yemen, and Somalia.
Arabian Nubian Shield Consists of juvenile continental crest that formed between 900 550 Ma, when intra
oceanic arc welded together along ophiolite decorated arc. Primary Au mineralization probably developed in
association with the growth of intra oceanic arc and evolution of back arc. Multiple episodes of deformation
have obscured the primary metallogenic setting, but at least some of the deposits preserve evidence that they
originate as sea floor massive sulphide deposits.
The Red Sea Hills Region is a vast span of rugged, harsh and inhospitable sector of the Earth with
inimical moon-like terrain, nevertheless since ancient times it is famed to be an abode of gold and was a major
source of wealth for the Pharaohs of ancient Egypt. The Pharaohs old workings have been periodically
rediscovered through time. Recent endeavours by the Geological Research Authority of Sudan led to the
discovery of a score of occurrences with gold and massive sulphide mineralizations. In the nineties of the
previous century the Geological Research Authority of Sudan (GRAS) in cooperation with BRGM utilized
satellite data of Landsat TM using spectral ratio technique to map possible mineralized zones in the Red Sea
Hills of Sudan. The outcome of the study mapped a gossan type gold mineralization. Band ratio technique was
applied to Arbaat area and a signature of alteration zone was detected. The alteration zones are commonly
associated with mineralization. The alteration zones are commonly associated with mineralization. A filed check
confirmed the existence of stock work of gold bearing quartz in the alteration zone. Another type of gold
mineralization that was discovered using remote sensing is the gold associated with metachert in the Atmur

Reducing Corrosion Rate by Welding DesignIJERD Editor
This document summarizes a study on reducing corrosion rates in steel through welding design. The researchers tested different welding groove designs (X, V, 1/2X, 1/2V) and preheating temperatures (400°C, 500°C, 600°C) on ferritic malleable iron samples. Testing found that X and V groove designs with 500°C and 600°C preheating had corrosion rates of 0.5-0.69% weight loss after 14 days, compared to 0.57-0.76% for 400°C preheating. Higher preheating reduced residual stresses which decreased corrosion. Residual stresses were 1.7 MPa for optimal X groove and 600°C
Router 1X3 – RTL Design and VerificationIJERD Editor
Routing is the process of moving a packet of data from source to destination and enables messages
to pass from one computer to another and eventually reach the target machine. A router is a networking device
that forwards data packets between computer networks. It is connected to two or more data lines from different
networks (as opposed to a network switch, which connects data lines from one single network). This paper,
mainly emphasizes upon the study of router device, it‟s top level architecture, and how various sub-modules of
router i.e. Register, FIFO, FSM and Synchronizer are synthesized, and simulated and finally connected to its top
module.
Active Power Exchange in Distributed Power-Flow Controller (DPFC) At Third Ha...IJERD Editor
This paper presents a component within the flexible ac-transmission system (FACTS) family, called
distributed power-flow controller (DPFC). The DPFC is derived from the unified power-flow controller (UPFC)
with an eliminated common dc link. The DPFC has the same control capabilities as the UPFC, which comprise
the adjustment of the line impedance, the transmission angle, and the bus voltage. The active power exchange
between the shunt and series converters, which is through the common dc link in the UPFC, is now through the
transmission lines at the third-harmonic frequency. DPFC multiple small-size single-phase converters which
reduces the cost of equipment, no voltage isolation between phases, increases redundancy and there by
reliability increases. The principle and analysis of the DPFC are presented in this paper and the corresponding
simulation results that are carried out on a scaled prototype are also shown.
Mitigation of Voltage Sag/Swell with Fuzzy Control Reduced Rating DVRIJERD Editor
Power quality has been an issue that is becoming increasingly pivotal in industrial electricity
consumers point of view in recent times. Modern industries employ Sensitive power electronic equipments,
control devices and non-linear loads as part of automated processes to increase energy efficiency and
productivity. Voltage disturbances are the most common power quality problem due to this the use of a large
numbers of sophisticated and sensitive electronic equipment in industrial systems is increased. This paper
discusses the design and simulation of dynamic voltage restorer for improvement of power quality and
reduce the harmonics distortion of sensitive loads. Power quality problem is occurring at non-standard
voltage, current and frequency. Electronic devices are very sensitive loads. In power system voltage sag,
swell, flicker and harmonics are some of the problem to the sensitive load. The compensation capability
of a DVR depends primarily on the maximum voltage injection ability and the amount of stored
energy available within the restorer. This device is connected in series with the distribution feeder at
medium voltage. A fuzzy logic control is used to produce the gate pulses for control circuit of DVR and the
circuit is simulated by using MATLAB/SIMULINK software.
Study on the Fused Deposition Modelling In Additive ManufacturingIJERD Editor
Additive manufacturing process, also popularly known as 3-D printing, is a process where a product
is created in a succession of layers. It is based on a novel materials incremental manufacturing philosophy.
Unlike conventional manufacturing processes where material is removed from a given work price to derive the
final shape of a product, 3-D printing develops the product from scratch thus obviating the necessity to cut away
materials. This prevents wastage of raw materials. Commonly used raw materials for the process are ABS
plastic, PLA and nylon. Recently the use of gold, bronze and wood has also been implemented. The complexity
factor of this process is 0% as in any object of any shape and size can be manufactured.

Secure Image Transmission for Cloud Storage System Using Hybrid SchemeIJERD Editor
- Data over the cloud is transferred or transmitted between servers and users. Privacy of that
data is very important as it belongs to personal information. If data get hacked by the hacker, can be
used to defame a person’s social data. Sometimes delay are held during data transmission. i.e. Mobile
communication, bandwidth is low. Hence compression algorithms are proposed for fast and efficient
transmission, encryption is used for security purposes and blurring is used by providing additional
layers of security. These algorithms are hybridized for having a robust and efficient security and
transmission over cloud storage system.
Application of Buckley-Leverett Equation in Modeling the Radius of Invasion i...IJERD Editor
A thorough review of existing literature indicates that the Buckley-Leverett equation only analyzes
waterflood practices directly without any adjustments on real reservoir scenarios. By doing so, quite a number
of errors are introduced into these analyses. Also, for most waterflood scenarios, a radial investigation is more
appropriate than a simplified linear system. This study investigates the adoption of the Buckley-Leverett
equation to estimate the radius invasion of the displacing fluid during waterflooding. The model is also adopted
for a Microbial flood and a comparative analysis is conducted for both waterflooding and microbial flooding.
Results shown from the analysis doesn’t only records a success in determining the radial distance of the leading
edge of water during the flooding process, but also gives a clearer understanding of the applicability of
microbes to enhance oil production through in-situ production of bio-products like bio surfactans, biogenic
gases, bio acids etc.
Gesture Gaming on the World Wide Web Using an Ordinary Web CameraIJERD Editor
- Gesture gaming is a method by which users having a laptop/pc/x-box play games using natural or
bodily gestures. This paper presents a way of playing free flash games on the internet using an ordinary webcam
with the help of open source technologies. Emphasis in human activity recognition is given on the pose
estimation and the consistency in the pose of the player. These are estimated with the help of an ordinary web
camera having different resolutions from VGA to 20mps. Our work involved giving a 10 second documentary to
the user on how to play a particular game using gestures and what are the various kinds of gestures that can be
performed in front of the system. The initial inputs of the RGB values for the gesture component is obtained by
instructing the user to place his component in a red box in about 10 seconds after the short documentary before
the game is finished. Later the system opens the concerned game on the internet on popular flash game sites like
miniclip, games arcade, GameStop etc and loads the game clicking at various places and brings the state to a
place where the user is to perform only gestures to start playing the game. At any point of time the user can call
off the game by hitting the esc key and the program will release all of the controls and return to the desktop. It
was noted that the results obtained using an ordinary webcam matched that of the Kinect and the users could
relive the gaming experience of the free flash games on the net. Therefore effective in game advertising could
also be achieved thus resulting in a disruptive growth to the advertising firms.
Hardware Analysis of Resonant Frequency Converter Using Isolated Circuits And...IJERD Editor
-LLC resonant frequency converter is basically a combo of series as well as parallel resonant ckt. For
LCC resonant converter it is associated with a disadvantage that, though it has two resonant frequencies, the
lower resonant frequency is in ZCS region[5]. For this application, we are not able to design the converter
working at this resonant frequency. LLC resonant converter existed for a very long time but because of
unknown characteristic of this converter it was used as a series resonant converter with basically a passive

series resonant tank of Lr and Cr converter acts very similar to Series Resonant Converter. The benefit of LLC
resonant converter is narrow switching frequency range with light load[6] . Basically, the control ckt plays a
very imp. role and hence 555 Timer used here provides a perfect square wave as the control ckt provides no
slew rate which makes the square wave really strong and impenetrable. The dead band circuit provides the
exclusive dead band in micro seconds so as to avoid the simultaneous firing of two pairs of IGBT’s where one
pair switches off and the other on for a slightest period of time. Hence, the isolator ckt here is associated with
each and every ckt used because it acts as a driver and an isolation to each of the IGBT is provided with one
exclusive transformer supply[3]. The IGBT’s are fired using the appropriate signal using the previous boards
and hence at last a high frequency rectifier ckt with a filtering capacitor is used to get an exact dc

“MS-Extractor: An Innovative Approach to Extract Microsatellites on „Y‟ Chrom...IJERD Editor
Simple Sequence Repeats (SSR), also known as Microsatellites, have been extensively used as
molecular markers due to their abundance and high degree of polymorphism. The nucleotide sequences of
polymorphic forms of the same gene should be 99.9% identical. So, Microsatellites extraction from the Gene is
crucial. However, Microsatellites repeat count is compared, if they differ largely, he has some disorder. The Y
chromosome likely contains 50 to 60 genes that provide instructions for making proteins. Because only males
have the Y chromosome, the genes on this chromosome tend to be involved in male sex determination and
development. Several Microsatellite Extractors exist and they fail to extract microsatellites on large data sets of
giga bytes and tera bytes in size. The proposed tool “MS-Extractor: An Innovative Approach to extract
Microsatellites on „Y‟ Chromosome” can extract both Perfect as well as Imperfect Microsatellites from large
data sets of human genome „Y‟. The proposed system uses string matching with sliding window approach to
locate Microsatellites and extracts them.
Importance of Measurements in Smart GridIJERD Editor
- The need to get reliable supply, independence from fossil fuels, and capability to provide clean
energy at a fixed and lower cost, the existing power grid structure is transforming into Smart Grid. The
development of a smart energy distribution grid is a current goal of many nations. A Smart Grid should have
new capabilities such as self-healing, high reliability, energy management, and real-time pricing. This new era
of smart future grid will lead to major changes in existing technologies at generation, transmission and
distribution levels. The incorporation of renewable energy resources and distribution generators in the existing
grid will increase the complexity, optimization problems and instability of the system. This will lead to a
paradigm shift in the instrumentation and control requirements for Smart Grids for high quality, stable and
reliable electricity supply of power. The monitoring of the grid system state and stability relies on the
availability of reliable measurement of data. In this paper the measurement areas that highlight new
measurement challenges, development of the Smart Meters and the critical parameters of electric energy to be
monitored for improving the reliability of power systems has been discussed.

Design of Context Aware Vertical Handoff

Abstract ––This work strives for mobile nodes to execute handoff decisions in an optimal way depending on the context.
This requires a dedicated procedure to efficiently collect and manage context information and an appropriate platform to
use that information for a most favorable handoff decision.
I. INTRODUCTION
In cellular networks such as GSM, a call is seamlessly handed over from one cell to another using hard handoff
without the loss of voice data. This is managed by networks based handoff control mechanisms that detect when a user is in
a handoff zone between cells and redirect the voice data at the appropriate moment to the mobile node via the cell that the
mobile node has just entered. In 4G networks a handoff between different networks is required. A handoff between different
networks is referred to as a Vertical handoff (VHO).
II. DESIGN OF CONTEXT AWARE VERTICAL HANDOFF
This work strives for mobile nodes to execute handoff decisions in an optimal way depending on the context. This
requires a dedicated procedure to efficiently collect and manage context information and an appropriate platform to use that
information for a most favorable handoff decision [1].
III. INTRODUCTION TO CONTEXT AWARE HANDOFF
Context information may be classified as static or dynamic, depending on the frequency and reason of changes. It
can be classified also based on where such information is maintained. Some pieces of information, such as the user’s profile,
appear twice, as the information is often spread over the user’s device, the operator’s network and possibly over several
service providers. As an example, the user’s profile may include subscribed services and service preferences, e.g., which
services have to be downgraded or dropped if available resources are not sufficient. The potential next AP, nearby APs, user
history, and user mobility can be used for location prediction and limit the options for selecting the next AP. It will help
simplifying the selection of the best AP. The user’s settings for applications and the types of the ongoing applications
indicate the preferable QoS level, etc.
We need a context management framework, which assures that the context information needed for handoff
decisions is available in time (before the handoff decision needs to be made) [2]. Moreover, exchange of information
between the network and the mobile nodes should be minimized to save wireless resources. Furthermore, a context-aware
handoff requires an appropriate execution platform, which is flexible enough to adapt to the changing requirements of this
service. It should be able to cope with dynamic context and automatically alter the handoff decision policy or the al gorithm
in use. It should support continuous exchange of context information between the nodes involved in the handoff service in an
efficient way. It should also enable the mobility manager of the mobile node to take the right handoff decision.

2. Design of Context Aware Vertical Handoff
IV. CONTEXT AWARE VERTICAL HANDOFF PROCEDURE
In this research we are designed the vertical handoff which takes into consideration the context generated in the network [3].
Figure 2: Sequence of Signaling for Service Deployment
The realization of our context-aware handoff service can be divided into five phases, which are explained in the
message sequence diagrams shown in Figure 2 and Figure 3. Phases A through C are referring to the service deployment
mechanism. During Phase D relevant context information is collected. In Phase E, the context information is evaluated and
handoff decisions are made.

The service deployment phases include: fetching the right service components; installing them on the appropriate
network node; and confirming the successful installation of all the components for that service. The HDM is installed on the
mobile node, and the HSM is installed on both the mobile node and the HM. More specifically, here we need to install
appropriate versions of both the HSM and HDM on the programmable platforms of the mobile node and HM. This is
realized by the service deployment mechanism in Phase A, B and C [4].
We assume that the SDS will trigger the module installation in the HM using the concept of service broadcast,
since the location and role of the HM are “fixed” comparing to the mobile node. On the other hand, the modules in the
mobile node are very dependent on the terminal and the user. The terminal can move frequently from one network to
another, or change its service. Therefore, it is better to have the mobile node initiating the module download with its
requested service. Whenever the conditions change in the mobile node, new requests will be sent to the SDS for new
services. The signaling used by the HDM to request the needed context information is detailed in Phase D. Context
information needed for handoff decision is requested using server-client based mechanism. The HDM is the client of the
HM, since the HM is the client of the Contextrepositories. After the HDM makes the decision on the target AP based on the
collected context information, in Phase E the decision is sent to the Mobility Management Component (MMC) of the mobile
node to execute the handoff [5].

To keep the consistency in the comparison, we have simulated the context aware handoff algorithm to convey
results in terms of number of handoff generated, delay and dropping probability Figure 4 shows the performance of context

aware handoff algorithm compared with CBSF handoff algorithms. In case of context aware handoff algorithm the number
of vertical handoff generated are less, this is because the design is such that the network a priori estimates the information
pertaining to a call/data transfer.

Figure 5: shows the performance in terms of delay.
The delay performance of context aware handoff algorithm is much enhanced as compared to CBSF handoff
algorithms. For lower traffic it is higher than CBSF but for higher traffic it is less. Further it is observed that the performance
of context aware handoff algorithm results very low variance in the delay for variable CBR traffic. (mean = 50.5 ms and σ =
59.71). This is the best feature of the designed algorithm.
In this research, the performance of network is evaluated in terms of dropping probability [6]. In number of
investigations, the performance is measured in terms of complexity of the handoff algorithm. Figure 6.illustrate the outcome
of the simulation carried out for context aware handoff algorithm and shows the comparison with CFBS algorithms. From
Figure 6, it is observed that the context aware handoff algorithm outperforms the CFBS algorithms, but for low traffic its
performance is equal to the algo-II (CFBS) for CBR traffic. For traffic of 100 packets per second algo-II gives a dropping
probability of 5 × 10-3 and the context aware algorithm results into 5 × 10 -5. Further it is observed that the variation of the
dropping probability for context aware handoff algorithm with respect to traffic is less, which suggests that the designed
algorithm is better for large variations in the traffic pattern.

Figure 8 shows the performance of context aware handoff algorithm in terms of delay. Table V shows the
comparison of delay characteristics for CBR and self-similar traffic. From figure 8 and Table V, it is observed that algo-I
gives minimum mean delay for CBR and self-similar traffic but the variance is not the minimum. Context aware handoff
algorithm offers moderate mean delay and the variance is minimum of all the three algorithms in discussion.

VI. CONCLUDING REMARKS
In this chapter, the concept of vertical handoff has been presented. To demonstrate the design of new context based
handoff algorithm, the analysis and performance evaluation of CFBS vertical handoff, in which two variants have been
designed and evaluated, has been presented first. Number of researchers dealt with the performance of vertical handoff for
complexity, throughput, etc. In this research, the dropping probability and delay characteristics have been considered as the
major performance metrics. To improve the performance of the network, a context aware handoff algorithm has been
designed and shown that it out performs the adaptive vertical handoffs giving moderate rise in delay characteristics. Most
importantly, the experimental work has been carried out to test the algorithms under considerations for CBR as well as self-
similar traffic.
