Du, Qinghe (2012-02-14)Due to the highly-varying wireless channels over time, frequency, and space domains, statistical QoS provisioning, instead of deterministic QoS guarantees, has become a recognized feature in the next-generation wireless ...
-
Leonard, Derek Anthony (2012-02-14)As the Internet has grown in size and importance to society, it has become increasingly difficult to generate global metrics of interest that can be used to verify proposed algorithms or monitor performance. This ...
-
Won, Myounggyu (2013-07-17)Complex Network Topologies (CNTs)–network holes and cuts–often occur in practical WSN deployments. Many researchers have acknowledged that CNTs adversely affect the performance of location-based routing and proposed various ...

Viqar, Saira (2012-10-19)In this dissertation we present deterministic algorithms for reliable and efficient communication in ad hoc networks. In the first part of this dissertation we give a specification for a reliable neighbor discovery layer ...

Xiong, Yunli (Texas A&M University, 2005-08-29)In wireless sensor networks (WSN), nodes have very limited power due to hardware constraints. Packet losses and retransmissions resulting from congestion cost precious energy and shorten the lifetime of sensor nodes. This ...
-
Jung, Eun Jae (2009-05-15)A local reconfiguration algorithm (INP) for reliable routing in wireless sensor networks that consist of many static (fixed) energy-constrained nodes is introduced in the dissertation. For routing around crash fault nodes, ...
-
Pandey, Nikhil (2012-07-16)Graph decompositions have useful applications in optimization problems that are categorized as NP-Hard. Modular Decomposition of a graph is a technique to decompose the graph into non-overlapping modules. A module M of ...

Easwaran, Gopalakrishnan (2010-01-16)Closed-loop supply chain (CLSC) management provides opportunity for cost savings through the integration of product recovery activities into traditional supply chains. Product recovery activities, such as remanufacturing, ...

Lee, Jaeyong (2009-05-15)Deployment of mobile nodes in a region of interest is a critical issue in building a mobile sensor network because it affects cost and detection capabilities of the system. The deployment of mobile sensors in essence is ...
-
Chen, Yu (Texas A&M University, 2006-10-30)This dissertation focuses on the design and analysis of distributed primitives for mobile ad hoc networks, in which mobile hosts are free to move arbitrarily. Arbitrary mobility adds unpredictability to the topology changes ...
-
Su, Hang (2012-02-14)As more and more wireless applications/services emerge in the market, the already heavily crowded radio spectrum becomes much scarcer. Meanwhile, however,as it is reported in the recent literature, there is a large amount ...

Subramanian, Sivaramakrishnan (2009-05-15)Mobile ad hoc networks consist of potentially moving, computing nodes that communicate via radio and do not have access to any fixed infrastructure. The knowl- edge about nearby nodes is a fundamental requirement and is ...
-
Cao, Guangtong (Texas A&M University, 2005-11-01)A mobile ad hoc network consists of certain nodes that communicate only through wireless medium and can move arbitrarily. The key feature of a mobile ad hoc network is the mobility of the nodes. Because of the mobility, ...
-
Zhang, Fenghui (Texas A&M University, 2008-10-10)Much research has been done on wireless sensor networks. However, most protocols and algorithms for such networks are based on the ideal model Unit Disk Graph (UDG) model or do not assume any model. Furthermore, many ...
-
Matthews, Suzanne (2012-07-16)Evolutionary relationships between a group of organisms are commonly summarized in a phylogenetic (or evolutionary) tree. The goal of phylogenetic inference is to infer the best tree structure that represents the relationships ...
-
Flow control techniques for real-time media applications in best-effort networks using fluid models Konstantinou, Apostolos (Texas A&M University, 2004-11-15)Quality of Service (QoS) in real-time media applications is an area of current interest because of the increasing demand for audio/video, and generally multimedia applications, over best effort networks, such as the Internet. ...
-
Huang, Tao (2009-05-15)Parallel prefix sums algorithms are one of the simplest and most useful building blocks for constructing parallel algorithms. A generic implementation is valuable because of the wide range of applications for this method. This ...

Gesmundo, Fulvio (2017-04-20)The notion of matrix rigidity was introduced by L. Valiant in 1977. He proved a theorem that relates the rigidity of a matrix to the complexity of the linear map that it defines, and proposed to use this theorem to prove ...
