Increasing Localization Precision In Sensor Networks With Mobile Beacons - A Genetic Path Planning Approach
(Computer Science & Engineering, 2009-09-16)
This work describes a genetic algorithm based approach to approximate an optimal path for a mobile beacon node in a grid of stationary wireless sensors. As the beacon moves over the field of sensors it broadcasts its ...
Towards An Implementation Of Avoip: Anonymous Voice-over-ip
(Computer Science & Engineering, 2009-09-16)
Voice over IP (VoIP) is one of the fastest growing telecommunicaiton market today. However with great popularity comes greater security risk. When we communicate over the Internet we expose our identity to all the prying ...
Use Of Wireless Signal Characteristics For Mobile Robotics Localization And Access Point Mapping
(Computer Science & Engineering, 2009-09-16)
Mobile robotics is an interesting and challenging emerging field in computer science.To properly achieve true autonomy, a robot must be able to determine where it is in relationshipto a global frame of reference and it ...
Design And Analysis Of A Mobile File Sharing System For Opportunistic Networks
(Computer Science & Engineering, 2009-09-16)
In the past several years, wireless mobile devices with advanced computing, sensing, and storing capabilities have been increasingly developed by handset manufacturers, deployed by wireless carriers, and accepted by ...
A Particle Filter Based Framework For Indoor Wireless Localization Using Custom Ieee 802.15.4 Nodes
(Computer Science & Engineering, 2009-09-16)
Locating people and objects as soon as possible and fair amount of precision has always been an important part of any organization or industry, especially in manufacturing, healthcare, and logistics. Systems that now have ...
Dynacet: A Minimum-effort Driven Dynamic Faceted Search System Over Structured Databases
(Computer Science & Engineering, 2009-09-16)
In this thesis, we propose minimum-effort driven navigational techniques for enterprise database systems based on the faceted search paradigm. Our proposed techniques dynamically suggest facets for drilling down into the ...
Adapting Harmonic Function Path Planning: To Reflect User Motion Preferences
(Computer Science & Engineering, 2009-09-16)
Every human in the real world has a unique motion preference while moving to achieve a given task. These preferences could be expressed by moving in a straight line, following the wall along a corridor, avoiding sharp ...
Modeling And Simulation Of A General Motors Conveyor System Using A Custom Decision Optimizer
(Computer Science & Engineering, 2009-09-16)
The temporal behavior of conveyor systems can be modeled using discrete event (DE) simulations. DE modeling provides a quick and cost effective method for analyzing complex problems as different scenarios can be tested ...
Pseudo-hierarchical Ant-based Clustering Using A Heterogeneous Agent Hierarchy And Automatic Boundary Formation
(Computer Science & Engineering, 2009-09-16)
The behavior and self-organization of ant colonies has been widely studied and served as the inspiration and source of many swarm intelligence models and related clustering algorithms. Unfortunately, most models that ...
Query Auditing Against Partial Disclosure
(Computer Science & Engineering, 2009-09-16)
Many government agencies, businesses, and nonprofit organizations need to collect, analyze, and report data about individuals in order to support their short-term and long-term planning activities. Statistical Databases ...
