A Gray Hole Attack (GHA) in dynamic wireless sensor networks (Dynamic WSN) is an attack that specifically drops or conveys occasion packets as the traded off hub moves. In such an attack, it is hard to recognize the traded off hub contrasted and the sending attack happening in the remote sensor arrange on the grounds that all sensor hubs move. To distinguish sending attacks in Dynamic WSN, a haze figuring based framework for a Gray hole recognition plot known as Fuzzy logic determining

... hs in Gray hole attack (FL-MP-GHA) has been proposed. In any case, since the proposed recognition conspire utilizes a solitary way, the vitality utilization of the sensor hub for course revelation when the sensor hub moves is substantial. To take care of this issue, the manuscript utilizes fluffy rationale to decide the quantity of multi-ways expected to improve the vitality effectiveness of sensor systems. Trial results demonstrate that the vitality productivity of the sensor organize is improved. Keywords : Gray hole attack (GHA), dynamic wireless sensor networks (Dynamic WSN), Fuzzy logic determining multi-paths in Gray hole attack (FL-MP-GHA).
