Wireless body area sensor networks (WBASNs) have gained much importance in current research domains and are implemented in real scenarios like hospitals for monitoring patients real-time data. Tiny sensing nodes in WBASNs have limited processing, storing capacity and battery life. The communication of sensing nodes is made energy efficient to conserve the(More)
Problem arising in CFG (Context Free Grammar) due to ambiguity can be trace to 1962. Even now there is no general method or procedure introduced to detect ambiguity in CFG. In parser generation and in language design, ambiguity in context free grammar, is a frequent problem as well as in application where it is used for the representation of physical(More)
