T.Deepa, Dr.M.Punithavalli |
| Abstract |
In Mining High-Dimensional Imbalanced
dataset(where one class outnumbers the other) feature
selection is an important and crucial task. Filtering
Technique is the simplest feature selection methodology used
to extract features in High-Dimensional database. This
paper involves evaluating the performance of commonly
used filtering techniques and proposes the accurate
technique for feature selection. The Techniques are
evaluated using micro array dataset.

| Abstract |
Sensor networks are collection of sensor nodes which co-operatively send sensed data to base station. As sensor nodes are battery driven, an efficient utilization of power is essential in order to use networks for long duration hence it is needed to reduce data traffic inside sensor networks, reduce amount of data that need to send to base station. The main goal of data aggregation algorithms is to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced. Wireless sensor networks (WSN) offer an increasingly Sensor nodes need less power for processing as compared to transmitting data. It is preferable to do in network processing inside network and reduce packet size. One such approach is data aggregation which attractive method of data gathering in distributed system architectures and dynamic access via wireless connectivity. Wireless sensor networks have limited computational power and limited memory and battery power, this leads to increased complexity for application developers and often results in applications that are closely coupled with network protocols. In this paper, a data aggregation framework on wireless sensor networks is presented. The framework works as a middleware for aggregating data measured by a number of nodes within a network.
The aim of the proposed work is to compare the
performance of TAG in terms of energy efficiency in comparison
with and without data aggregation in wireless sensor networks and
to assess the suitability of the protocol in an environment where resources are limited. |

| Abstract |
Long-Term Evolution (LTE) is the next-generation
beyond 3G network. LTE uses OFDM (orthogonal
frequency-division multiplexing) radio access
technology together with advanced antenna
technologies. In addition to LTE, 3GPP has
specified a flat, IP-based network architecture as
part of the system architecture evolution (SAE)
effort. It is the natural evolution of 3GPP GSM,
WCDMA, and 3GPP2 CDMA networks.LTE
security must provide at least the same level of
security as provided by 3G security functions and
still minimize the effect on the previous
architecture. Authentication service is one of the
most essential services in LTE networks, which has
significant effects on internet security. First, we
review the Security analysis and architecture of
LTE . Then, we review the standardized
authentication protocol such as PAP, LEAP ,EAP-
TLS. More-over, we will review some papers
related to the security issues and solutions on EAP
TLS security protocol.We also further make some
comparisons to these schemes on their features and
performance. Finally,we conclude some future
works for the interworking between LTE and
WiMAX networks. |

SUITUATION BASED INTELLIGENCE ROUTING IN WIRELESS SENSOR NETWORK |

D.karthik, Dr.S.Nagarajan |
| Abstract |
Wireless sensor nodes are driven by limited power supply
where replacing or charging the batteries are not feasible. This paper
studies situation based intelligence routing as power minimization
technique. It uses an intermediate node to send out the packet, based
on the power passed by each sensor node and in case of fault
tolerance. Thus intelligence routing reduces power consumption by
minimizing the life time of the network when intelligence routing is
being applied. This paper explains what is situation based
intelligence routing, its benefits and how the routing changes
dynamically. Intelligence routing reduces the power consumption by
minimizing the number of transmissions required to communicate a
given amount of information across the network Evaluation results
indicate that the proposed solution is more efficient than non
intelligence routing which still meeting the required lifetime
constraints. |

Implementation Of An Enhanced File Search Efficiency In P2P Network |

| Abstract |
The original intent of the peer-to-peer (P2P)
concept is to treat each participant equally, heterogeneity widely
exists in deployed P2P networks. In many aspects peers are
different from each other such as bandwidth, CPU power, and
storage capacity. Various approaches have been taken with the
use of query forwarding heterogeneity i.e. the high band width of
powerful nodes can be fully initialized to increase the system
capacity. In this paper, we suggest to directly improve the search
efficiency of P2P network using the query answering
heterogeneity. In our proposed Differentiated Search
(DiffSearch) algorithm, the peers with high query answering
capabilities will have the highest priority to be queried. Since the
query answering capacities are extremely unbalanced among
peers by querying a small portion of a network a high query
success rate can be achieved. The search traffic is further
reduced due to the shrunken search space. For example, the
random walk or DHT can still be applied in the ultrapeer overlay
to further reduce the search traffic, which will be investigated in
this paper. This paper analysis and implement flooding search,
proposed diffsearch algorithm, diff search algorithm with
random walk techniques and compare these algorithm and
finally show that the DiffSearch algorithm with random walk can
save more than 80 percent of search traffic. |

| Abstract |
Knowledge about the status of the female
reproductive system is important for fertility problems and
age related family planning. The volume of these fertility
requests in our emancipated society is steadily increasing.
Transvaginal ultrasound imaging of the follicles in the
ovary gives important information about the ovarian aging,
i.e., number of follicles, size, position and response to
hormonal stimulation. Manual analysis of many follicles is
laborious and error-prone. In this paper, a new method for
recognition of follicles in ultrasound images of ovaries is
proposed. This fully automated segmentation method is
based on active contours without edge method. The
proposed technique is tested on ultrasonographic images of
ovaries. The experimental results are compared with
inferences drawn by medical expert and demonstrate the
efficacy of the method. |
