A mobile ad hoc network (MANET) is outlined as a network of mobile devices that can coordinate and communicate among themselves without any prior administration. Energy efficient lifetime maximizing methods based on channel awareness in MANETs result in better performance of the networks until the nodes energy is capable of handling control messages. In the existing approach, the nodes lifetime and consistency of packet flow are defaced due to unplanned energy conservation methods. This results in a tradeoff between network throughput and node energy, resulting in post network failure. The post network failure results in limited TTL of the nodes and retarded network throughput with higher control overhead. To bridge the gap between network throughput and energy conservation under limited overhead, a Transition State supporting cooperative MAC broadcast protocol for both conserving node energy and to utilize available node in an effective manner prior to their energy drain is proposed in this paper. TSMP reduces the total energy consumption to a maximum extent of 14–21% higher than DPCMP and 24–33% than SPCMP. And comparatively, the routing overhead falls almost 45–52% than SPCMP and 27–31% than DPCMP.
