Internet of Things (IoT) has pretty much taken the digital world by storm. The way of information being produced and outputted is through m communication.But, with sensors acting as middlew brings us with even higher state of connectivity and interactivity. On the basis paper discusses and addresses the issues of packet monitoring of IoT device simulations in Cooja framework. Addressing this issue is tantamount to addressing the security and packet loss issue in Cooja framework; a simulator provided by Con develop and run IoT enabled systems.
