wireless sensor networks can be promptly understood simply by thinking about what they essentially are: a large number of small sensing self-powered nodes which gather information or detect special events and communicate in a wireless fashion‚ with the end goal of handing their processed data to a base station. Sensing‚ processing and communication are three key elements whose combination in one tiny device gives rise to a vast number of applications [A1]‚ [A2]. Sensor networks provide endless

Becoming a Network Administrator October 3‚ 2013 Becoming a Network Administrator I have always had a strong interest in technology and computer networks. After years of strenuous personal deliberation I finally made the decision to focus on obtaining a career as a network administrator. I had to weigh many options in making this decision and ultimately I decided that network administration had more positive aspects than negative. In my deliberations I learned that the network administration

Hierarchical Network There are many benefits associated with hierarchical network designs. Scalability Hierarchical networks scale very well. The modularity of the design allows you to replicate design elements as the network grows. Because each instance of the module is consistent‚ expansion is easy to plan and implement. For example‚ if your design model consists of two distribution layer switches for every 10 access layer switches‚ you can continue to add access layer switches until you have

Rosenblatt’s Perceptron ORGANIZATION OF THE CHAPTER The perceptron occupies a special place in the historical development of neural networks: It was the first algorithmically described neural network. Its invention by Rosenblatt‚ a psychologist‚ inspired engineers‚ physicists‚ and mathematicians alike to devote their research effort to different aspects of neural networks in the 1960s and the 1970s. Moreover‚ it is truly remarkable to find that the perceptron (in its basic form as described in this

Wireless Network Security Partha Dasgupta and Tom Boyd Dept. of Computer Science and Engineering Fulton School of Engineering Arizona State University partha@asu.edu‚ tboyd@asu.edu Abstract Wireless networking is inherently insecure. From jamming to eavesdropping‚ from man-inthe middle to spoofing‚ there are a variety of attack methods that can be used against the users of wireless networks. Modern wireless data networks use a variety of cryptographic techniques such as encryption and authentication
