Neural Networks are being used for character recognition from last many years but most of the works were reported to English character recognition. Character recognition is one of the applications of pattern recognition, which has enormous scientific and practical interest. Many scientific efforts have been dedicated to pattern recognition problems and much(More)
The Request-to-Send and Clear-to-Send (RTS/CTS) mechanism was introduced to minimize the collisions due to "Hidden Nodes" in wireless networks. It tried well to solve this problem over Carrier Sense Multiple Access (CSMA), but it gave rise to some more problems. These problems are "Exposed Node Problem", "False Blocking Problem" and "Masked Node Problem".(More)
