This paper presents Novel Deg-Greedy algorithm based on Dominating Nodes (DN) and cooperative jamming scheme for secure transmission of big data in wireless cloud networks. Each node has a transmission radius in a multi-hop wireless cloud network that can transmit a message to all of its neighbours positioned in the radius. A Dominating Node (DN) based virtual backbone plays an important role in wireless networks for efficient routing and broadcasting. In the proposed algorithm, the same message is sent by a source node sends to all the leading nodes in the network. A dominating node is selected based on degree based evaluation of the given cloud network. The dominating nodes broadcast the requesting big data message to its path, if it finds the requested information along the path it sends the content to the destination node. During this path of flow there may presence of eavesdroppers and it is prevented by emitting jamming signal by adopting cooperative jamming scheme. The novel algorithm is analyzed by splitting the network as Strongly Perfect Network (SPN), Strongly Weekly Perfect Network (SWPN) and Weekly Strongly Perfect Network (WSPN).
