摘要：In wireless networks for cooperative relaying, some nodes eavesdrop on the data send from the sender node relay it to the receiver node. We increase the capability of the network by optimizing relay node choosing and decreasing the count of hops. The topology control problem is then prepared as a distinct stochastic optimization trick that is decided using a stochastic estimation method. The existing systems effects in time delay in choosing alternative node due to node crash and inadequate ability to transfer the file. But each node in our proposed system encrypts and decrypts the file according to node capability to evade node crash. We choose the best node to transfer the file by assessing its impartial task and making the intervention set of the chosen relay node. The outcomes divulge that that our suggestion achieves better in the system connectivity, time factor and correct relay node choice than the multi hop communication. The performance of multi hop scheduling and Optimized Cooperative Scheduling (OCS) are compared in terms of probabilities, end to end delay, losses occurred and network capacity.
