Abstract: Complex event processing (CEP) combines information from different sources to infer events or patterns that recommend a lot of difficult circumstances. The goal of complex event processing is to search out significant events and reply to them as quickly as doable. Complex event processing may be integrated into 2 forms specifically Active-rule complex Event processing (ACEP) and In-Network Distributed complex Event processing (INDCEP). Active rules in ACEP enable us to specify a pattern query's dynamic condition and real-time actions. The technical challenge is to handle interactions between queries and reactions to queries within the high-volume stream execution. In-Network Distributed complex Event processing (INDCEP) is employed to perform the process inside the network by pushing complex event processing into network nodes. It focuses on distributed event detection via diffusing distributed plans into a network of sensing element nodes to perform complex event tasks. In this paper, we discuss about real time risks, tackle by active rule embedded CEP and processing by pushing CEP into the network nodes by INDCEP. By comparing these two integrated forms we conclude that In Network Distributed Complex Event Processing is more efficient since it meets both real time requirements and network characteristics.
