Aziz Ur Rahaman
Makandar1 and K. Karibasappa2
Abstract : The wavelet transform has emerged
as a cutting edge technology, within the field of image compression research.
Wavelet theory and subband coding have created a surge of interest in
wavelet based applications during the past decade. Image coding
(or compression)is an important application that has benefited
significantly from the wavelet theory. Lossless image coding using the
Embedded Zerotree Wavelet (EZW) is the main focus of this work and also in
the sequel to this work. The main purpose of this paper is to
investigate the impact and quality of orthogonal wavelet filter for EZW.
Meanwhile, we also look into the effect of the level of wavelet decomposition
towards compression efficiency. The wavelet filters used are Haar
and Dauhechies 4. The experimental results have been compared
and qualitative analysis is done on the basis of time taken for
compression & error after decompression for medical images.
Key words: lossless, image coding, EZW, wavelet.

1S. N. Panda and 2Gaurav Kumar
Abstract : Intrusion detection and corrective measures in the
networks is one of the challenges in the fast growing world of Cyber Crime.
The network establishments are facing various types of threats on
routine basis. To efficiently transmit information across a network, there
is need of an improved and reliable architecture. The intrusion
detection systems should be developed with utmost care to avoid any natural
or intentional attempts. Moreover, the packet encryption algorithm
should be developed in such a way so that cracker is not able to change even
a single bit in the confidential data. This paper proposes an
efficient algorithm for Packet Encryption as well as the standard to detect
any kind of intercept attempt.

A Review of Intradomain Packet Routing Optimization in IP Networks
Rakesh Kumar1 and Mahesh
Kumar2
Abstract : This paper presents recent work on Intradomain
routing optimization using legacy protocols, and identifies important
areas where further research is needed. The shortest and optimal routing
is discussed in context of intradomain routing protocols. An
alternative to having the distributed routing protocols adept to the prevailing
traffic, the network operator or automated network management tools
can modify the configuration of static parameters that derive the
operation of routing protocols using traffic engineering concepts. The
Objective of routing optimization is to balance the traffic load in the
network with the goal to improve quality of service (QoS) and optimal
utilization of available resources. The paper also provides the literature on
traffic engineering and other algorithms that contributing to the
optimization of Intradomain routing.
Key words: Intra-domain routing protocols, Quality of
service, Routing Optimization, Traffic Engineering.

Distributed remote method invocation
1Anil Rajput,
2Neeraj Bhargava 3Hemraj Singh Thakur, 4Manmohan Singh and
5Shivshakti Shrivastav
Abstract : An emerging trend in the Signal and Image Processing
(SIP) community is the appearance of middleware and middleware
standards that can be readily exploited for distributed computing applications
by the SIP community. High performance computing and
High Performance Embedded Computing (HPEC) applications will
benefit significantly from highly efficient & portable computational
middleware for signal & image processing. Open middleware standards such
as VSIPL, MPI, CORBA, Data mining RMI, and Web Services (based
on SOAP/XML), offer a unique opportunity for the rapid development
of easily maintained HPEC codes that combine portability and
flexibility across a number of applications This middleware infrastructure
will support the rapid development and deployment of portable,
efficient, SIP critical applications that will be of immediate benefit to many.
The use of distributed computing technologies for problem solving has
been around for many years. The early paradigm of distributed
computing has been that of remote procedure calls (RPC). However, in
recent years, this paradigm has shifted to the use of remote objects due to
the acceptance of object oriented programming practices. Even today
web services are built around the concept of messaging and frequently
these messages take the form of request/response-type remote procedure
calls on remote objects. The existing and emerging standards for
performing distributed computing have resulted in several possible
middleware choices for the SIP community. This paper focuses on three
specific middleware standards for distributed computing, namely: the
Common Object Request Broker Architecture (CORBA).
Index Terms: Remote method invocation, Object
request broker, Inter-object communication, Distributed embedded
computer systems, Distributed object models, data mining AI.

Ajay Jangra1 Deepa
Sharma2 Jasbir Singh3 and
Priyanka4
Abstract : Software Engineering works as systematic,
disciplined, quantifiable tool to the development, operation, and maintenance
of software. In software development life cycle many models have
been developed to evaluate and improve their capabilities. This
paper proposed two new D-tables (decision tables
i.e. D1, D2) which
provide necessary guidelines to the developer/ organisation on decision
making regarding selecting System Development methodology (SDM)
by "Comparing traditional and object oriented SDM". This work is
novel in the sense it comprises traditional and object oriented SDM
models, analyzing with respect to pros. & cons. and guide the developer
to select particular SDM approach. The required result may depend
on organization's decision that how well they create software
according to how they define and execute their processes. In this paper, we
focus on different approaches of SDM and try to find out the suitability
of different SDM approaches in software.
Key
words: software development methodology
(SDM), SDLC, Object oriented system design, user, developer,
SRS.

Image Enhancement : A Pre-Processing Technique
Ms. Ketki R. Ingol1 and
V K. Shandilya2
Abstract : An image can be synthesized from a micrograph of
various cell organelles by assigning a light intensity value to each cell
organelle. The sensor signal is "digitized"— converted to an array of
numerical values, each value representing the light intensity of a small area
of the cell. Digital image processing is an area characterized by the
need for extensive experimental work to establish the viability of
proposed solutions to a given problem. Image processing modifies pictures
to improve them, extract information, and change their
structure. Image enhancement improves the quality (clarity) of
images for human viewing. Removing blurring and noise, increasing
contrast, and revealing details are examples of enhancement operations.
For example, an image might be taken of an endothelial cell, which
might be of low contrast and somewhat blurred. Reducing the noise
and blurring effect and increasing the contrast range could enhance
the image. The original image might have areas of very high and very
low intensity, which mask details.
Key words: histogram equalization, grey values, dft,
Fourier transform.

Routing Protocols for Mobile Sensor Networks
Rajesh Yadav#1 and Dilbag
Singh#2
Abstract : Mobile sensor networks (MSNs) have been widely studied
in recent years and are expected to be applied in a variety of
applications such as battlefield surveillance, event detections, hostile
environment monitoring, and wild animal tracking. In this report, we list out
the existing routing protocol for wireless sensor networks. A WSN
is composed of a large number of sensor nodes that are densely
deployed either inside the phenomenon or very close to it. The position of
sensor nodes need not be engineered or predetermined. This allows
random deployment in inaccessible terrains or disaster relief operation. In
this paper we study different type of routing protocol for sensor
network like flooding, SPIN (Sensor Protocols for Information via
Negotiation), LEACH (Low Energy Adaptive Clustering Hierarchy) in details
and check how they different from the ad hoc network. SPIN and
LEACH routing protocol are compared with flooding protocol.

Implementation of digital logic in generation of symmetric key for cryptography
Poonam Rathee1, Davinder Rathee
and Kehar Singh
Abstract : Cryptography is the art of achieving security by encoding
messages to keep the information non-readable. Cryptography actually is a
mathematical scrambling and unscrambling of data to achieve, Confidentiality
(Readable only to sender and receiver); Integrity (not modified by any one to integrity
of message); Non repudiation (sender can't refuse the claim of not sending);
and Entity authentication. While sending or receiving the data, special keys
are used to encrypt/decrypt data to verify the original contents. This key
makes the process of cryptography secure. There are two approaches for the
generation of encryption/decryption keys
i.e software and hardware. The purpose of
this paper is to generate encryption key using hardware technique. To
design electronics circuit basic concept is derived from encoding and decoding
of data vis four different channels at different times. Selections of channels
will be guided by timer and decoder circuits. one form to another from at
transmitter end receiver end respectively. The purpose of this paper is to generate the
key code using electronic circuits to make the data secure.
