The impacts on topology control and network capacity, especially in mobile ad hoc networks (MANETs), which can establish a dynamic network without a fixed infrastructure. A node in MANETs can function both as a network router for routing packets from the other nodes and as a network host for transmitting and receiving data. MANETs are particularly useful when a reliable fixed or mobile infrastructure is not available. The topology control issues in MANETs with cooperative communications lead to propose a Capacity-Optimized Cooperative (COCO) topology control scheme to improve the network capacity in MANETs by jointly optimizing transmission mode selection, relay node selection, in MANETs with cooperative communications. As an advancement to the COCO, with the topology control improvement, also suggesting the transmission selection from one to another using best path strategy and forwarding the information securely by encrypting the messages being transmitted between the MANETs.
