MANETs are decentralized, infrastructure-less and dynamic wireless networks. The mobility of nodes in the networks is one of the most striking features of MANETs. MANETs are very useful in situations where the deployed nodes keep changing their positions. Here packet transmissions take place through the intermediate nodes connecting the source to the destination. The dynamic nature and flexibility of MANETs lead to complex issues like frequent link breaks and quick exhaustion of energy, which needs to be addressed effectively. Cooperative communication is a fast-growing research area, which focuses on improving the lifetime and flexibility of the network‟ robustness. A number of research works have been published which focus on how to exploit cooperative communication techniques to enhance the capability of MANETs. But most of the research work has laid stress on the enhancement of lower layers. Numerous issues still persist in the Network layers, which are yet to be addressed completely, requiring considerable research. This paper reviews some of the works done on cooperative routing protocols for Adhoc wireless network by systematically analyzing their limitations, benefits, working principles and core characteristics. The protocols are studied in depth to analyze their performance and compare them.
