A User Friendly Toolkit for Building Robust Environmental Sensor Networks
Found in: Communication Networks and Services Research, Annual Conference on
By John-Paul Arp, Bradford G. Nickerson
Issue Date:May 2007
pp. 76-84
Wireless sensor network research is growing rapidly, but building and deploying real-world wireless sensor network applications still requires the assistance of technology experts. We present a user friendly toolkit that simplifies the process of building ...
 
Sensor Web Adaptation to Dynamic Sensor Networks
Found in: Communication Networks and Services Research, Annual Conference on
By Gunita Saini, Bradford G. Nickerson
Issue Date:May 2011
pp. 137-144
As nodes appear and disappear in a Wireless Sensor Network (WSN), communication protocols acting in the data link, network and transport layers adapt dynamically to the new network structure. We present an extension of the dynamic nature of WSNs to the web...
 
A Sensor Web Language for Mesh Architectures
Found in: Communication Networks and Services Research, Annual Conference on
By Bradford G. Nickerson, Zhongwei Sun, John-Paul Arp
Issue Date:May 2005
pp. 269-274
A Sensor Web Language (SWL) for mesh architectures is presented. The mesh SWL architecture was extended from a hierarchical structure to provide a more robust environment to deploy, maintain and operate sensor networks. Alerts, direct sensor node communica...
 
Reasoning About Nuclear Physics Processes
Found in: Tools with Artificial Intelligence, IEEE International Conference on
By Sri Hartati, Bradford G. Nickerson, George R. DeMille
Issue Date:November 1995
pp. 228
This paper discusses a model for reasoning about nuclear physics processes. Nuclear Process Theory (NPT) is a formal knowledge representation system for nuclear physics processes. Knowledge of the nuclear physics process is expressed in terms of a basic nu...
 
Communicating and Displaying Real-Time Data with WebSocket
Found in: IEEE Internet Computing
By Victoria Pimentel,Bradford G. Nickerson
Issue Date:July 2012
pp. 45-53
Internet communication provides a convenient, hyperlinked, stateless exchange of information, but can be problematic when real-time data exchange is needed. The WebSocket protocol reduces Internet communication overhead and provides efficient, stateful com...
 
End-to-End Acknowledgement for Data Collection in Wireless Sensor Networks
Found in: Communication Networks and Services Research, Annual Conference on
By John-Paul Arp, Bradford G. Nickerson
Issue Date:May 2010
pp. 93-101
A novel method to improve the reliability of data collection in wireless sensor networks is presented. The Disseminated ACKnowledgment protocol (DACK) builds on collection and dissemination protocolsto provide end-to-end acknowledgement of data samples. A ...
 
I/O-Efficient Rectangular Segment Search
Found in: Computational Science and its Applications, International Conference
By Gautam K. Das, Bradford G. Nickerson
Issue Date:March 2010
pp. 61-67
We consider the I/O-efficient rectangular segment search problem in 2D. The problem involves storing a given set ${\cal S}$ of $N$ line segments in a data structure such that an axis aligned rectangular range query ${\cal R}$ can be performed efficiently; ...
 
An Adaptive Programming Model for Environmental Sensor Networks Using Fuzzy Logic
Found in: Communication Networks and Services Research, Annual Conference on
By Bradford G. Nickerson, Ke Deng
Issue Date:May 2008
pp. 350-357
In this paper, we present a sensor network programming model using fuzzy logic. A fuzzy controller model is used to dynamically control the rate of observation of environ-mental variables. Differing rates arise from changing environmental conditions. Infer...
 
A Language for Wireless Sensor Webs
Found in: Communication Networks and Services Research, Annual Conference on
By Bradford G. Nickerson, Jing Lu
Issue Date:May 2004
pp. 293-300
A language for wireless sensor webs called the Sensor Web Language (SWL) is presented. SWL is especially useful for transmitting information over low-power wireless networks with relatively low bandwidth. The language has been designed for automated transl...
 
Efficient search of moving objects on a planar graph
Found in: Proceedings of the 16th ACM SIGSPATIAL international conference on Advances in geographic information systems (GIS '08)
By Bradford G. Nickerson, Thuy Thi Thu Le
Issue Date:November 2008
pp. 1-8
We present a dynamic spatio-temporal data structure called the Graph Strip Tree (GStree) for indexing objects constrained to move on a graph. The GStree is designed to efficiently answer range queries about the current or past positions of moving objects. ...
