Enhancement of Users Call Logging facilities using Push Down Automata (PDA) with Real Time Constraint Notation (RTCN)
This paper highlights the use of Push – Down Automata (PDA) in storing and maintaining the call logs. The special feature about this paper is to maintain incoming call record from the different mobile service provider in a mobile in clustered way to the user. It focuses on real time constraint notation being applied to the push down automata for formal verification of the model.
