Routing Techniques in Wireless Sensor Networks: A Survey
- IEEE WIRELESS COMMUNICATIONS
, 2004
"... Wireless Sensor Networks (WSNs) consist of small nodes with sensing, computation, and wireless communications capabilities. Many routing, power management, and data dissemination protocols have been specifically designed for WSNs where energy awareness is an essential design issue. The focus, howeve ..."

, and coherent-based depending on the protocol operation. We study the design tradeoffs between energy and communication overhead savings in every routing paradigm. We also highlight the advantages and performance issues of each routing technique. The paper concludes with possible future research areas.
View-Dependent Refinement of Progressive Meshes
"... Level-of-detail (LOD) representations are an important tool for realtime rendering of complex geometric environments. The previously introduced progressive mesh representation defines for an arbitrary triangle mesh a sequence of approximating meshes optimized for view-independent LOD. In this paper, ..."

, we introduce a framework for selectively refining an arbitrary progressive mesh according to changing view parameters. We define efficient refinement criteria based on the view frustum, surface orientation, and screen-space geometric error, and develop a real-time algorithm for incrementally refining
ALLIANCE: An Architecture for Fault Tolerant Multi-Robot Cooperation
- IEEE Transactions on Robotics and Automation
, 1998
"... ALLIANCE is a software architecture that fa- cilitates the fault tolerant cooperative control of teams of heterogeneous mobile robots performing missions composed of loosely coupled subtasks that may have ordering dependencies. ALLIANCE allows teams of robots, each of which possesses a variety of hi ..."

A framework for information systems architecture.
- IBM Syst. J.,
, 1987
"... With increasing size and complexity of the implementations of information systems, it is necessary to use some logical construct (or architecture) for defining and controlling the interfaces and the integration of all of the components of the system. This paper defines information systems architect ..."

Also, some preliminary conclusions about the implications of the resultant descriptive framework
Segmentation using eigenvectors: A unifying view
- In ICCV
, 1999
"... Automatic grouping and segmentation of images remains a challenging problem in computer vision. Recently, a number of authors have demonstrated good performance on this task using methods that are based on eigenvectors of the a nity matrix. These approaches are extremely attractive in that they are ..."

of this approach, the estimation process leads to a notoriously di cult optimization. The frequently used EM algorithm [3] often converges to a local maximum that depends on the initial conditions. Recently, anumber of authors [11, 10, 8, 9, 2] have suggested alternative segmentation methods that are based
FEATURES OF WSN AND VARIOUS ROUTING TECHNIQUES FOR WSN: A SURVEY
"... A Wireless Sensor Network is the collection of large number of sensor nodes, which are technically or economically feasible and measure the ambient condition in the environment surrounding them. The difference between usual wireless networks and WSNs is that sensors are sensitive to energy consumpti ..."

. Furthermore, these protocols can be classified into multi-path based, query based, negotiation-based, QoS-based, and coherent–based, depending on the protocol operation. In this paper the survey of routing techniques in WSNs is shown. It is also outlined the design challenges and performance metrics
ROAMing Terrain: Real-time Optimally Adapting Meshes
, 1997
"... Terrain visualization is a difficult problem for applications requiring accurate images of large datasets at high frame rates, such as flight simulation and ground-based aircraft testing using synthetic sensor stimulation. On current graphics hardware, the problem is to maintain dynamic, view-depend ..."

Dynamic View-Dependent Simplification for Polygonal Models
, 1996
"... We present an algorithm for performing view-dependent simplifications of a triangulated polygonal model in real-time. The simplifications are dependent on viewing direction, lighting, and visibility and are performed by taking advantage of image-space, objectspace, and frame-to-frame coherences. A c ..."

Furthermore, these protocols can be classified into multipath-based, query-based, negotiation-based, QoS-based, and coherent based depending on the protocol
Speculative Versioning Cache
- In Proceedings of the Fourth International Symposium on High-Performance Computer Architecture
, 1998
"... Dependences among loads and stores whose addresses are unknown hinder the extraction of instruction level parallelism during the execution of a sequential program. Such ambiguous memory dependences can be overcome by memory dependence speculation which enables a load or store to be speculatively exe ..."
