Nowadays, Sensor nodes are utilized in widespread distribution. Thus, security issues are a significant apprehension in the Wireless Sensor Networks (WSN). The gray hole attack is a particularly damaging kind of assault that, in addition to bringing down WSNs, brings down whole networks and interferes with the flow of data. A hash signature algorithm (IGDH) is proposed to solve these problems to improve data integrity for Gray hole attack detection. During the process of route discovery in the network, this strategy makes use of an algorithm that generates a hash signature to detect the Gray hole attack. The recipient node gets the message from any sensor and verifies the sensor node hash signature. During data transmission, the recipient node checks the principal communication count (PCC) and size of the data packet; if the packet size is equal Accept the message; otherwise, the recipient node decides some packets are dropped and isolates that node is a grayhole attacker. The simulation results explain the proposed method has better packet delivery and minimizes the packet loss and miss detection ratio in the WSN.
