5G network system is the option for better coverage, capacity and spectral efficiency. Overall targets for the 5G network are to have higher throughput per area per user with lower latency. 5G can be the answer to ever growing number of users to their growing demands. The main focus is on implementation of D2D communication which reduces burden on cellular infrastructure and increases the spectral efficiency. Unlike the traditional one, traffic has to go to the base station first even if the users are within short range of each other. Another important factor is security. A network suffers from various types of attacks especially a network like 5G which works in unlicensed spectrum A technique is being proposed for detection of malicious node, a kind of trap method is used for the detection of malicious nodes. When the grey node is detected due to the trap, an alarm is triggered to make the other nodes aware of malicious nodes. So, the network performance has been checked under three condition i.e. when the network is in ideal state (WITHOUT GREY NODE), affected from the attack (WITH GREY NODE) and network after attack (REMOVED GREY NODE). The considered parameters are Throughput, Packet delivery Ratio, Delay, and Success rate. These parameters have shown the considerable improvements as compared to the network suffering from the grey hole attack.
