Intelligent load balancing in mobile ad hoc networks

Khanna, Varun (Wichita State University, 2010-12)

On demand ad hoc routing protocols such as AODV and DSR do not look for new routes unless there is a change in the network topology. In scenarios where same intermediate node is used for longer time, this behavior may cause ...
Interoperability of ad-hoc routing protocols

Raghuveer, Madhusudhan (Wichita State University, 2008-05)

Mobile ad-hoc networks are fast emerging and play a very important role in the field of wireless communications. With the advantages of mobility and infrastructure less the applications of ad-hoc networks have increased ...
IP multicast admission control for IPTV

Jayaraman, Deepa (Wichita State University, 2012-05)

Video streaming over the Internet has become the most sought after application and is growing at a very fast rate. Internet Protocol Television (IPTV) is a technology that has been growing fast, replacing traditional cable ...
ISCSI performance for mobile appliances using intermediate target storage

Arragattu, Prashanth Kumar (Wichita State University, 2009-05)

Looking at the present demand for mobile services we can predict that there will be an explosive growth in the usage of mobile appliances in the future. But these mobile appliances suffer from significant problems related ...
iSCSI performance over RDMA-enabled network

Pallampati, Amarnath (2006-07)

With an increase in the amount of information being exchanged every day, there is a need for storage repositories and faster networks to retrieve data with a minimum amount of time delay. Keeping this in mind, inroads have ...
Iterative EM channel estimation for turbo-coded DS CDMA receiver under different communication scenarios

Bijukchhe, Neelu (Wichita State University, 2008-05)

This thesis proposes a scheme of obtaining an estimate of channel coefficients and noise power spectral density (PSD) using iterative expectation maximization based on a turbo-coded code-division multiple-access (CDMA) ...
Iterative low-complexity multiuser detection and decoding for coded UWB systems

Sathish, Arun D. (2006-07)

In general, ultra wideband (UWB) signals are transmitted using ~'eIYshort pulses m tiIae domain, thus promising very high data rates. In this thesis, a recei'ler structure is proposed for decoding multiuser information ...
Label-free electrical immunoassay biosensors for early disease diagnosis

Brandigampala, Savindra Madhavi (Wichita State University, 2012-05)

This thesis focused on developing an inexpensive and user friendly “point- of- care” (POC) device for early disease diagnosis. Proteomics research has elucidated many new proteins as biomarkers that have the potential to ...
LDPC encoded pilots for iterative receiver improvement

Hassan, Khurrum (2005-12)

Turbo and low density parity check (LDPC) codes show performances approaching Shannon capacity. This thesis proposes a novel iterative channel estimation and LDPC decoding scheme where the pilot symbols are encoded and can ...
LDPC-like approach for distributed detection in Wireless Sensor Networks

Shukair, Mutaz Z. (Wichita State University, 2007-12)

LDPC codes have many applications in channel and source coding. In this thesis, we apply LDPC-like belief propagation algorithm to address distributed detection problem in Wireless Sensor Network. The objective is to achieve ...
Linear quadratic regulator design for doubly fed induction generator using singular perturbation techniques

Aravinthan, Abhiramy (Wichita State University, 2012-07)

Doubly fed induction generators (DFIG) are widely used in wind power generation because of their ability to be operated at varying rotational speeds while producing power output at a constant frequency. Electrical dynamics ...
Local caching architecture for RFID tag resolution

Thadani, Prakash (Wichita State University, 2007-12)

Radio Frequency Identification (RFID) is set to become the standard in identification and tracking of items worldwide with projected numbers in tens of billions in a few years. With the reducing size and cost of RFID ...
Location-aware replication in virtual Hadoop environment

RajuladeviKasi, UdayKiran (Wichita State University, 2012-12)

MapReduce is a framework for processing highly distributable tasks across huge datasets using a large number of compute nodes. As an implementation of MapReduce, Hadoop is widely used in the industry. Hadoop is a software ...
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 ...
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)
