Technical Paper: Energy-aware Security Management Utilizing Adaptive Security Mechanisms for Wireless Sensor Network

1 Reply

Energy has been an important subject these recent years. While some people are advocating more efficient and sustainable use of energy through the green energy movement, some scientific and engineering fields should include efficient energy usage into the equation in order to provide an effective solution. One of these fields is wireless sensor network. Wireless sensor network is a subdomain of distributed system. The network consists of distributed nodes that communicate one another wirelessly. As the name entitles, nodes are equipped with sensing capability (humidity, temperature, air pressure, etc) and these sensed data should be delivered to a collecting point, which is usually named sink node, to be processed later. Unlike traditional network that is connected to sufficient power-supply, nodes in wireless sensor network (other than sink node) are usually restricted to energy-constraint. The nodes are mostly powered by battery packages and due to the placement of these nodes in topographically challenging area, frequent battery replacement is undesirable. Thus, it is imperative to involve efficient energy usage in the design.

Whitepaper – An Introduction to Private Cloud

Leave a reply

As the word “cloud computing” becomes more ubiquitous these days, several questions can be raised ranging from basic question like the definitions of a cloud and cloud computing to more tempting questions like architecture of cloud infrastructure and implementation of cloud computing to solve complex, data-intensive compute problems.

Concerns raised over the cloud computing are mainly related on how secure and reliable the cloud is to support enterprise-level requirements. The notion of offloading data and process to third party infrastructure or software providers in cloud computing may not be a sound idea in the enterprise realm. This article will briefly summarize private cloud, a type of cloud environment which is designed to be run with stringent requirements that may fit the enterprise-level SLAs.

Querying XML Documents, Revisiting Existing Languages and Methodologies

Leave a reply

XMLThese days in the web 2.0 era, we are using XML extensively. We use xml on our browser, to represent the hypertext. We use xml in our most recent MS Word documents. We use XML in web services. We use XML in our AJAX applications. To the bigger scale, the enterprise, we also use XML in the service oriented architecture implementation.We fall onto XML as our first choice for universal data format. And also databases?

As a plain text data representation, XML should incur extra overhead for the size and processing time. Indexing XML documents is also another issue, not to mention providing relational data on top of XML documents. Building pure XML database is non-trivial, hence we hardly find implementation for such. However, given all the disadvantages of utilizing XML as the database, is it still possible to do basic database functionality for XML documents?

Fortunately, the answer is yes.

I provide a paper containing my survey to existing approaches to querying XML documents and achieving database functionality over XML documents. Although the structure of the paper may be inclined to academic domain, i think it will still be useful for developer who is looking for quick hindsight for such matter.
