Wireless networking Essays

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

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

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

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? Answer: Installing multiple accesspoints in WLL in a building properly enhances the performance of the wifi networks overall. It helps to avoid co-channel and adjacent channel interferenc as too much co-channel or adjacent channel interference will degrade the performance of your wireless network

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

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

Abstract – A main requirement in high performance networks is multicast communication, which involves transmitting information from a single source node to multiple destination nodes. A multicast assignment is a mapping from a set of network nodes called as source nodes, to a maximum set of network nodes called destination nodes with no overlapping allowed among the destination nodes of different source nodes A network is said to be nonblocking for multicast assignments, if for any legitimate multicast

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
