Analysis of path duration in mobile ad-hoc networks

Srinivasan, Manivannan (Wichita State University, 2008-05)

Estimation of path duration in MANET's is useful and it can be used in various ways to improve the performance of communication in MANET's. One such application is the assignment of optimum route cache TTL for "on demand" ...

Connection probability in reference point group mobility model

Kaur, Ramneet (2006-12)

In ad hoc wireless mobile networks, the mobility of wireless nodes plays a significant role in evaluating the network’s performance. As the nodes are mobile there is a frequent transition between the connections of nodes ...

Distributed source coding using non binary LDPC

Potluri, Madhurima (2005-12)

In this thesis we have extended non binary low-density parity-check (LDPC) codes, developed for channel coding, to be used for source coding to compress correlated non binary sources. Focusing on the asymmetric case of ...

Distributed video coding using non-binary LDPC codes

Chilumuru, Suma (2006-12)

Distributed coding is a new paradigm for video transmission, based on the Wyner-Ziv theorem. In this thesis, a new Wyner-Ziv codec was proposed using non-binary Low-Density Parity-Check (LDPC) codes. Non-binary LDPC codes, ...

Estimation of path duration in mobile ad-hoc networks: A theoretical study

Devaraj, Sreekalyan (Wichita State University, 2009-12)

Mobile ad hoc networks (MANETs) are widely deployed for different purposes. Some of these areas are for the military, emergency rescue operations, etc. These networks are established "on the fly" and, therefore, play a ...

Flexible autonomous robotic task scheduling using advanced RISC machines

Zaccagni, Zachary James (Wichita State University, 2008-08)

This research presents two methods for a group of Garcia robots to collaboratively decide which task to attend to, and to move to their respective locations. One method allows for a needed flexibility and dynamic analysis ...

Image change detection using wireless sensor networks

Yelisetty, Sree Ramya (2007-05)

Change detection in images is of great interest because of its relevance in many applications such as video surveillance. This thesis presents the underlying theoretical problem of distributed image change detection using ...

Image registration in low resolution visual sensor networks

Balasubramanian, Harini (Wichita State University, 2007-12)

Image registration is the process of integrating data from different coordinate systems into one coordinate system. It is of great interest in video surveillance because of its capability to combine images and generate a ...

Information theoretic analysis of the capacity of multi channel digital image watermarking

Kothinti, Kalyan Reddy (2005-12)

Watermarking channel capacity is defined as the highest rate in bits per image of information that can be embedded with arbitrarily low probability of detection error under a given distortion between original and watermarked ...

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 ...

Model to estimate the number of sessions handled by conference server in session initiation protocol conferencing solution with less delay and the optimum processing capacity

Venugopalan, Natarajan (Wichita State University, 2009-07)

The recent introduction of conferencing products such as telepresence has led to immense growth in the number of voice conferencing calls on the internet protocol (IP) network. Currently, voice conferencing users are ...
