ABSTRACT
Routing protocols have an important role in any Mobile Ad Hoc Network (MANET). Researchers
have elaborated several routing protocols that possess different performance levels. In this paper we
give a performance evaluation of AODV, DSR, DSDV, OLSR and DYMO routing protocols in
Mobile Ad Hoc Networks (MANETS) to determine the best in different scenarios. We analyze these
MANET routing protocols by using NS-2 simulator. We specify how the Number of Nodes parameter
influences their performance. In this study, performance is calculated in terms of Packet Delivery
Ratio, Average End to End Delay, Normalized Routing Load and Average Throughput.

6. A PROPOSED NOVEL APPROACH FOR SENTIMENT ANALYSIS AND
OPINION MINING
Ravendra Ratan Singh Jandail, Galgotias University, India
ABSTRACT
As the people are being dependent on internet the requirement of user view analysis is increasing
Exponentially. Customer posts their experience and opinion about the product policy and services.
But, Because of the massive volume of reviews, customers can’t read all reviews. In order to solve this
problem, a lot of research is being carried out in Opinion Mining. In order to solve this problem, a lot
of research is being carried out in Opinion Mining. Through the Opinion Mining, we can know about
contents of whole product reviews, Blogs are websites that allow one or more individuals to write
about things they want to share with other The valuable data contained in posts from a large number of
users across geographic, demographic and cultural boundaries provide a rich data source not only for
commercial exploitation but also for psychological & sociopolitical research. This paper tries to
demonstrate the plausibility of the idea through our clustering and classifying opinion mining
experiment on analysis of blog posts on recent product policy and services reviews. We are proposing
a Nobel approach for analyzing the Review for the customer opinion

8. SMARTPHONE PREVENTIVE CUSTOMIZED POWER SAVING MODES
Ahmed Sameh and Abdulla Al-Masri, Prince Sultan University, KSA
ABSTRACT
The postulate of this paper is that current smartphones' power saving modes can be improved towards
saving more power and/or gain more user satisfaction only if they start following “preventive” and/or
user customized power saving plans. We develop a number of preventive power saving modes that
save the battery power without the need of using the power of the same battery for detecting abusage.
It will be supporting the user with a preventive plan that could give him/her an idea about what to run
or don’t run. Another issue of current power saving modes is the “One Size Fits All” philosophy which
does not take into consideration the factors that could distinguish different smartphone users, for
example, the nature of the workspace of the user (Indoor/Outdoor), the age, the gender and/or the
user’s applications categories of interests. The paper develops a strategy to match a smartphone power
saving mode with its perfect smartphone user by classifying smartphones users into classes depending
on a set of different factors and having the user to identify himself/herself to the smartphone before the
first use.
