    Abstract: Many application fields require detecting real-time composite events and reacting to them immediately
considering their sensitive condition. This raises the need for efficient, situational aware Complex Event
Processing (CEP) engines to handle massive amount of streamed data. To satisfy this need an optimization
method to enhance the engine's efficiency and reliability is proposed. It adopts a combination of enhanced
buffer allocation method with pattern matching process under the supervision of domain expert. An error
detection and recovery to handle any failure case is proposed with the system to assure high reliability and
accuracy in delivering and detecting the events. The proposed system is evaluated in terms of performance over
time, throughput, error rate and pattern detection accuracy. A comparative evaluation with a state-of-art engine
is done and the proposed system outperformed it under challenging workloads.
