Scalability of Ad Hoc Dynamic Spectrum Access Networks

Abstract :-

Dynamic Spectrum Access allows wireless users to access a wide range of spectrum which increases a node’s ability to communicate with its neighbors, and spectral efficiency through opportunistic access to licensed bands. Our study focuses on the scalability of network performance, which we define in terms of network transport capacity and end-to-end throughput per node, as the network density increases.

Performance Evaluation of Symmetric Encryption Algorithms on Power Consumption for Wireless Devices

Abstract :-
This paper illustrates the key concepts of security, wireless networks, and security over wireless networks. Wireless security is demonstrated by applying the common security standards like (802.11 WEP and 802.11i WPA,WPA2) and provides evaluation of six of the most common encryption algorithms on power consumption for wireless devices namely: AES (Rijndael), DES, 3DES, RC2, Blowfish, and RC6. A comparison has been conducted for those encryption algorithms at different settings for each algorithm such as different sizes of data blocks, different data types, battery power consumption, date transmission through wireless network and finally encryption/decryption speed.

Analyzing the Energy Consumption of Security Algorithms for Wireless LANs

Abstract :-
Security in wireless networks is of paramount importance. Due to the broadcast nature of the wireless radio signals, wireless networks are implicitly vulnerable to several network attacks. Anyone within the wireless transmission range of a device (including malicious users or attackers) is able to passively listen to or eavesdrop on the signals and could potentially access information from the signals. It is also possible to actively transmit signals that can attack the network. Encryption algorithms play good roles in information security systems (ISS).

Evaluating the Effects of Cryptography Algorithms on power consumption for wireless devices

Abstract :-
Security is important for wireless networks, mainly because the communications signals are openly available as they propagate through the air. The security settings can be different in many factors, but the main factors are the choice of ciphers used to provide security functions, the key length, and the number of operational rounds, packet size, and data types. These factors also have a significant impact on the energy consumption for providing security.
