Computer Science (CS) spans the range from theory to practice to cutting−edge inventions. CS makes graduates aware of
new technologies and new ideas and is a foundation for many different computing careers. Computer Scientists design and build
software and create efficient solutions to real−world problems in fields such as robotics, computer−enhanced vision,
and digital forensics.
The need for computing professionals and executives right here in the . is growing as companies become more global. Almost every major challenge facing our world is turning to computing for a solution, from conquering disease to eliminating hunger, from improving education to protecting the environment.
WSN nodes resource constrained. In order to keep the size and the cost of the nodes down, the nodes have limited processing power, memory and radio range. However, the resource constraint which has the most significant impact on many WSNs is the constraint on energy. WSN nodes are battery operated. Many wireless sensor networks are deployed in locations where battery replacement is not feasible. A node has to be discarded when the battery depletes. Energy scavenging may alleviate this problem in some sensor networks. Most WSN protocols are very conscious of the limited supply of energy, and try to conserve energy.
