Research ArticleOpen accessIn the abstractEnhancing Wireless Medium Access Control Layer Misbehavior Detection System in IEEE 802.11 NetworkA. M. Alsahag, M. OthmanWireless Medium Access Control (MAC) protocols such as IEEE 802.11 use distributed contention resolution mechanisms for sharing the wireless channel. In this environment, selfish hosts that fail to adhere to the MAC protocol may obtain an unfair throughput share. For example, IEEE 802.11 requires hosts competing for access to the channel to wait for a "back-off" interval, randomly selected from … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,967 accessesView PDFCite

Research ArticleOpen accessIn the abstractAnimation of Natural Language Specifications of Authentication ProtocolsMabroka A. Mayouf, Zarina ShukurProblem Statement: A few visualization tools have been created for protocol design and analysis. Although these tools provide an environment for designing security protocols, each one has its own protocol definition language (its also called informal specification language). The problem is that the user should understand the language which related to the used tool in order to define an exist … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,736 accessesView PDFCite
Research ArticleOpen accessIn the abstractFuzzy Assignment Procedure based on Categories' BoundariesGeorge Rigopoulos, John Psarras, Dimitrios Th. AskounisWe presented a procedure for multicriteria assignment problems. Assignment to a category is based on the comparison between an action and categories’s boundaries. Boundary is represented by the least typical action that can be included in the category, and is considered as the category’s inclusion threshold. Comparison is executed considering performance on evaluation criteria and calculation of a fuzzy inclusion … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractCreep-Fatigue Crack Growth Interaction in Nickel Base Supper AlloyF. DjavanroodiMost engineering components which operate at elevated temperatures are subjected to non-steady loading during service. This paper describes the current fracture mechanics concepts that are employed to predict cracking of Nickel base supper alloy materials at high temperatures under low and high frequency cyclic loading. A model for predicting creep crack growth in terms of C* and the creep uniaxial … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,895 accessesView PDFCite
