interest in 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

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

for the people how far apart they are. After this radio based communication systems Era started. It was an extension of wired based networks. In the beginning it was developed for some special purposes like military and police usage. With the passage of time these systems emerged to allow common peoples to communicate with each other‚ rather then using wired based network. After this the age of faster communication and capabilities of voice get started and evolved into new telecommunication system.
