Description: Routing in WSN as an Optimization Problem
Routing in Wireless sensor networks can be viewed as an optimization problem in which there is a need to find the optimal path (which is not necessarily the shortest one) in terms of some parameters like energy, delay and reliability.

Description: pear to be accurate enough in case MAC reliability is not used as when packet
drops occurs due to collisions buffer drains and size is decreased. Well known schemes
use a combination of channel utilization and buffer occupancy, as seems to be the most
effective method. Fidelity measurement at the sink is also used but is more slow method,
as end-to-and and processing delay is added at the sink.
Talking for Feedback methods local ones are most frequently used as transient
congestion problems are most usual in wireless sensor networks and quick reaction is
needed in these situations.
Control Methods used in different schemes is the most important part. The u

Description: This paper presents a model for reliable packet delivery in
Wireless Sensor Networks based on Discrete Parameter Markov
Chain with absorbing state. We have demonstrated the
comparison between cooperative and non cooperative automatic
repeat request (ARQ) techniques with the suitable examples in
terms of reliability and delay in packet transmission. Platform: |

Description: Energy consumption is prominent and critical issue faced by wireless sensor networks.
The maximum amount of energy is consumed when the sensors communicate with each other.
Therefore energy efficient routing mechanisms are required. In this paper, a routing scheme based
on the fisheye state routing with a difference in route selection mechanism has been proposed to
ensure the reduction in the overall energy consumption of the network. This scheme is named as
Energy-Aware Fisheye State Routing (EA-FSR). It is simulated considering various parameters
using QualNet5.0. Performance of EA-FSR has been compared with the original fisheye state routing algorithm which is also simulated in the same environment. For comparison various parameters
like end-to-end delay average, energy consumption and throughput have been considered. Platform: |

Description: This book is now in its fifth edition. Each edition has corresponded to a dif
ferent phase in the way computer networks were used. When the first edition ap
peared in 1980, networks were an academic curiosity. When the second edition
appeared in 1988, networks were used by universities and large businesses. When
the third edition appeared in 1996, computer networks, especially the Internet, had
become a daily reality for millions of people. By the fourth edition, in 2003, wire
less networks and mobile computers had become commonplace for accessing the
Web and the Internet. Now, in the fifth edition, networks are about content dis
tribution (especially videos using CDNs and peer-to-peer networks) and mobile
phones are small computers on the Internet.
New in the Fifth Edition
Among the many changes in this book, the most important one is the addition
of Prof. David J. Wetherall as a co-author. David brings a rich background in net
working, having cut his teeth designing metropolitan-area networks more than 20
years ago. He has worked with the Internet and wireless networks ever since and
is a professor at the University of Washington, where he has been teaching and
doing research on computer networks and related topics for the past decade.
Of course, the book also has many changes to keep up with the: ever-changing
world of computer networks. Among these are revised and new material on
Wireless networks (802.12 and 802.16)
The 3G networks used by smart phones
RFID and sensor networks
Content distribution using CDNs
Peer-to-peer networks
Real-time media (from stored, streaming, and live sources)
Internet telephony (voice over IP)
