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.
*For admission to the Faculty of Graduate Studies and Research (FGSR), our TOEFL iBT (Test of English as a Foreign Language Internet-Based Test) total score requirement is stated above. When a student presents a score report that meets or exceeds FGSR’s total score requirements, but where the Speaking or Listening scores are 18 or 19, departments can contact the student by phone or Skype to determine the student’s level of speaking and listening comprehension. If the student is able to carry on a conversation, and if the listening skills meet your expectations, please send a supporting letter addressing the low TOEFL score along with the application for admission and other admission documents.
