Packet switching: Pros: Network lines are only used when messages need to be sent, meaning the 90% inactive time of users can be used by other users who need to send information right away. By splitting up data into packets, only packets that are corrupted needs to be resent rather than the whole data. Routers can dynamically route packets along different paths to provide a potentially more optimal path for all users. Cons: Packets can arrive out of order meaning end users will have to spend extra
In today’s world the technology which is made wireless communication easier is Bluetooth technology which is used for transferring data in short range. People who are looking to gain information in an unauthorized manner is viewed very closely to any new improvement or invention. Security of data is very important aspect in Bluetooth .Bluetooth security has many other different versions of bluetooth regarding security and speed of transferring the data which is to be according to the need and demand
To get started the LAN would be the main configuration for connecting the computers on each floor with star typology. Star topology will connect all nodes individually to a central connection point also known as the switch. A pro with this configuration if a cable fails only one node will be brought down and the rest will continue running. In addition, we can use twisted pair for the wire used to simply to cancel out electromagnetic interface from external sources since there will be multiple computers
WiFi connection is made by using a wireless adapter(that converts digital information to radio waves and back with antenna) to create a hotspots that allow access to internet service. WiFi technology is using 802.11 networking standards (802.11a, 802.11b, 802.11n etc. ) that will depend on needs for the user. In wireless networks there are two logical typologies that are use, a star and point-to-point (devices connect directly to each other and do not need access point device to communicate), in general
Abstract: Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. For such a reasons this technology has become popular. Though it is familiar, its wireless channel is vulnerable to the eavesdroppers during message delivery (security is the major problem). In the previous cases this problem was solved by cryptographic
telephone wire (ADSL) or fibre optic cable. As the latter is now capable of speeds in excess of 100Mb, an increasing number of homes have "superfast" fibre optic connections. Mobile broadband uses the same technology as mobile phones to give you internet access wherever you go with your laptop, netbook, tablet or iPad. It 's slower and usually comes with a relatively low download limit, but allows you greater flexibility away from home.
BLUETOOTH SECURITY STANDARDS 4.1 Wireless Security One of the major problems with wireless technologies is their security. Non-wireless networking technologies require to tap into the actual line to see the flow of bits, however, with wireless all you have to do is be in the range of the transmitting device. This allows anyone with a receiver to pick up the bits “flapping in the breeze”. This causes security to be one of the main areas of concentration for all wireless technologies. 4.2 Four Essentials
Pros & Cons Pros • Easy to install: Wireless networks have become commonplace with Wireless N being the current standard. Wireless router is easy to purchase, connect it to the Internet, and install in either at home or office setting, it is recommended to hire a network professional to install and setup the wireless router in order to ensure that you have high level of security enabled and there is sufficient wireless coverage throughout the whole areas. • Cost: The cost of the hardware is low,
2.1 Wireless LAN Infrastructure Devices Proper WLAN infrastructure design requires understanding and deploying QoS (Quality of Service) on the wireless network to ensure end-to-end data / video/voice quality on the entire network. Like a traditional wired LAN, WLAN is a grouping of computers and peripheral devices that share a common communications backbone. As per the name itself, a WLAN allows users to connect to the LAN through radio transmission. The below mentioned are the most common components
who have secure attachment can cope with difficult events in their lives in a better way. It is actually connected point with resiliency, however, we do not have any further information about this relationship between attachment and resiliency. In psychology and counseling literature, there are two bodies of knowledge: attachment and resilience. These theories have crucial points for one’s life. However, literature has lack of evidence to find a connection between them. Since attachment and resiliency

Wireless protocols have evolved over the years, there are many new models being created that push more bandwidth data using wireless technology. In most cases the older, wireless models are more sensitive to interference, which in turn result for the protocol to fallback to slower modes for the data to get though (insert). According to an article that PCmag.com wrote, there are three limitation to 802.11b limited bandwidth, radio interference from other devices and networks, and security concerns
In 1884, F.B. Morse, developed the Morse code for efficient communication. It is because of the simplicity yet efficaciousness that these Morse codes are used even today. Morse codes are composed of ditz and dahs, which are used by a number of people for communication purposes. Moreover, the use of these codes is not limited for simple communication. It is also used for encrypted communication for security purposes. This code is used for Emergency Signaling (SOS) for all kinds of receivers. This

has actually now gone wireless. Smart phone, as the name suggests, supplies movement. It is a portable communication device. One can bring it anywhere. It is enabled by satellites that transmit signals for the phone to receive and send. It is very practical as one can use it anywhere irregardless of time and area. People everywhere have seen the development of communication innovation, from a phone that utilizes wires to one that no longer requires any. In some places, wireless phones were provided
are routed to their corresponding destination. Here, all connections once again share the link connecting RN and node 1. This process needs additional N-1 wavelengths. Thus, atleast 2N-2 wavelengths are required for the above connections. At this point, when a new connection of the form arrives, it needs another new wavelength. Thus, atleast wavelengths are required for this worst case multicast assignment. Therefore, 2N-1 wavelengths are sufficient and necessary for a WRMD WDM unidirectional
5. METHODOLOGY 5.1 Secure Multipath Routing Protocols in Wireless Sensor Networks Till date many routing protocols have been proposed for wireless sensor networks, but only few of them consider the problem of security [4] and most of them are developed without any security concern. So in this section we focus at selected multipath routing protocols in order to cope with the various attacks. For avoiding intruders attacks in HWSN various methods and algorithms are implemented out of that Professor
1) Explain the difference between access point and a portal. Answer: The difference between an access point and a portal is that an access point acts as a bridge and it enables the linking of various separate 802.11 wireless LANs whereas the portal is the one which provides a point for interconnection between a wired LAN and an 802.11 wireless LAN. 2)Why are multiple accesspoints in WLL installed in a building?
