Mobile AdHoc Networks (MANETs) has a wide range of applications, ranging from everyday mobile phone application to mission critical military applications. MANETs have proved their necessity and the ease of setting up networks. Thus MANETs are very popular for scenarios which are sensitive and urgent like disaster relief, military applications, etc. As the application of MANETs increases, the attacks on MANETs also increase. A vast range of research is being conducted to keep routing in MANETs robust and secure. One of the major research area is routing privacy. Many routing solutions are proposed to maintain privacy. Location aided routing is a novel idea; in which routing is done based on location information, therefore node identity is not revealed. This paper outlines few of the routing algorithms in MANETs.
