Description: Wireless Sensor Networks (WSN) are becoming popular day by day,
however one of the main issue in WSN is its limited resources. We
have to look to the resources to create Message Authentication Code
(MAC) keeping in mind the feasibility of technique used for the
sensor network at hand. This research work investigates different
cryptographic techniques such as symmetric key cryptography and
asymmetric key cryptography. Furthermore, it compares different
encryption techniques such as stream cipher (RC4), block cipher
(RC2, RC5, RC6 etc) and hashing techniques (MD2, MD4, MD5,
SHA, SHA1 etc). The result of our work provides efficient
techniques for communicating device, by selecting different
comparison matrices i.e. energy consumption, processing time,
memory and expenses that satisfies both the security and restricted
resources in WSN environment to create MAC.

Description: Energy Harvesting wireless sensor network(EH-WSN) is a kind of WSN that
uses rechargeable power supply instead of using traditional battery.
In traditional WSN, the energy sources is limited. When the power source of
node nish, it can not continue to work unless it is recharged again. So the
eort was to design energy-e cient network protocols to maximize the lifetime
of WSN by minimizing energy usage.if we can have access to unlimited power, we can have in nite
lifetime in network. This unlimited power can be provide by environment such
as light, vibration and heat. Then stores the harvested energy in a storage
device. When the device uses energy harvested instead of battery, the residual
energy is no more an useful quantity to preserve. In EH-WSN, if the rate of
harvesting power is lesser than the power used by the node, the sensor node
should go to sleep to charge up.

Description: As we know, the energy needed for sensors should be electrical. So the rst
step before start to work is to convert environmental energy to electrical one.
Inside the node there are dierent components for sensing the area, collecting
data and processing the data. So the main dierent part of this kind of nodes,
in compare of WSN nodes, is the power part. Once the stored energy reach
to a certain amount, the power supply for micro controller and transceiver will
start to work. They will continue to work until they have energy, as soon as the
energy nish, they stops and energy storage device start to work to save energy
again.
The other fact should be consider about EH-WSN node is that the available
energy can change in dierent nodes. So every node has its own harvesting rate.

Description: A combining breadth-first search (BFS) or depth-first search (DFS) with aware range to find minimum connected dominating set
A backbone in a Wireless Sensor Network (WSN) reduces the communication overhead, increases the bandwidth efficiency, decreases the overall energy consumption and thus increases network operational life.The nodes in a wireless sensor network forward data towards a sink via other nodes. The limited resources on the nodes require minimum energy to be spent in this energy consuming task. This necessitates a virtual backbone that can minimize the number of hops required to reach the sink assuming that all nodes have equal transmission range. In the wireless domain, this backbone is a minimum connected dominating set.
In this paper, I propose using breadth-first search (BFS) or depth-first search (DFS) with given range to find minimum connected dominating set.

Description: Mobile wireless sensor networks (MWSNs) have recently launched a growing popular class of WSN in which mobility plays a key
role in the execution of the application. In recent years, mobility has become an important area of research for the WSN community. The
increasing capabilities and the decreasing costs of mobile sensors make mobile sensor networks possible and practical. Although WSN deployments
were never envisioned to be fully static, mobility was initially regarded as having several challenges that needed to be overcome,
including connectivity, coverage, and energy consumption, among others.However, recent studies have been showing mobility in a more
favorable light. In this article, an overview of proposals that evaluate mobile communication in WSNs is presented.

Description: It is a novel fuzzy based sleep mode technique for WSN that turns off the ONUs
(placed at the customer premises) when certain traffic conditions are verified. The objective is to
achieve an improved energy efficiency without impacting too much the Quality of Service
perceived by end-users. The whole operation is managed at the central Node and the length of the sleep time periods is computed employing a statistical method.-It is a novel fuzzy based sleep mode technique for WSN that turns off the ONUs

Now-a-days the demand for home automation systems in homes and offices are invariably increasing. The home automation system is a key for energy conservation that can be equipped in normal buildings. As there are many benefits of wireless technology over wired, most of the home automation systems are based on the WSN technology. In this paper we present the design and implementation of a smart home based on LabVIEW using wireless sensor network system. The system can monitor the temperature, light, fire & burglar alarm of the house and have infrared sensor to guarantees the family security. The monitored data is automatically stored into an excel file. The system can be connected to internet to monitor the security of home anywhere in the world.-Smart home is a house that uses technology to monitor the environment with the help of various sensors, control the electrical appliances and communicate the outer world.
