MAC layer misbehavior detection and reaction in wireless networks

Shenbagaraj, Anbarasan (Wichita State University, 2012-07)

IEEE 802.11 wireless LAN medium access control (MAC) provides transmission fairness to nodes in a network. A misbehaving node can modify its MAC and operate in a selfish manner to improve its own performance (throughput) ...
Mac layer misbehavior effectiveness and collective aggressive reaction approach

Giri, VamshiKrishna Reddy (Wichita State University, 2010-12)

Current wireless MAC protocols are designed to provide an equal share of throughput to all nodes in the network. However, the presence of misbehaving nodes (selfish nodes that deviate from standard protocol behavior in ...
A macro level environmental performance comparison: dry machining process vs wet machining process

Lodhia, Prashant (2007-05)

The metal cutting process, known as conventional machining process, utilizes cutting fluids to provide lubrication, cooling and easy chip removal. The long-term effects of cutting fluids disposal into the environment are ...

Maintenance oriented optimal design of accelerated degradation testing

Hamada, Murad (2006-12)

In this dissertation, the problem of using accelerated degradation testing data for reliability estimation is studied and demonstrated. Simulation and analytical approaches have been investigated. By simulation which ...
Mapping controllers from the s-domain to the z-domain using magnitude invariance and phase invariance methods.

Vadhavkar, Prathamesh R. (Wichita State University, 2007-12)

Design by emulation has been widely used in the field of control systems. Design by emulation is a process where initially a continuous time controller is designed to achieve desired closed loop specifications. This ...
Maximizing data preservation time in intermittently connected sensor networks

Hou, Xiang (Wichita State University, 2012-05)

In intermittently connected sensor networks, wherein sensor nodes do have connected paths to the base station periodically, preserving generated data inside the network is a new and challenging problem. We propose to ...
Measurement of energy consumption in Wireless LANs and Radio Frequency Identification systems

Ramamoorthy, Suresh (Wichita State University, 2011-07)

As mobile hand-held devices such as cell phones and personal digital assistants are battery operated, it is important to minimize their energy consumption. The limited lifetime of the battery is always a problem for all ...
Measuring anonymity while sending and receiving multiple messages

Samad, Abdus (Wichita State University, 2012-05)

Anonymity systems are designed in a way that hides the level of communication between senders and receivers of a message, and the goal of an attacker is to find that communication pattern. It is usually very difficult to ...
Mechanical and electrical properties of aligned carbon nanofiber/epoxy nanocomposites

Lim, Chee Sern (Wichita State University, 2010-05)

Carbon Nanofibers (CNFs) are high aspect ratio nanofillers that possess excellent mechanical and electrical properties. Hence, CNFs have been incorporated into polymer to fabricate nanocomposites with superior mechanical ...
Mechanical testing and evaluation of high-speed and low-speed friction stir welds

Banwasi, Nitin (2005-12)

The potential of the Friction Stir Welding (FSW) process is easily observed in the creation of defect free welds in almost all of the Aluminum alloys. The success and applicability of the process, however, will depend on ...
A methodology for aircraft seat certification by dynamic finite element analysis

Bhonge, Prasannakumar (Wichita State University, 2008-12)

Dynamic aircraft seat regulations are identified in the Code of Federal Regulations 1(CFR), 14 CFR Parts 23.562 and 25.562 for crashworthy evaluation of a seat in a dynamic environment. The regulations specify full-scale ...
