Research review of development of novel routing algorithms for mobile Ad-hoc networks

Routing in mobile adhoc networks is always an issue of great significance and key focus of researchers from last decade. The design of legacy routing protocols was simpler due to little dependency of applications on routing algorithms. However the large scale inception of mobile devices in market drives application developers to develop many novel applications. The applications require high processing speeds, larger memory, more battery power and high utilization of bandwidth. These applications on one hand created challenges for hardware designers to design fast and efficient processors and other entities and on the other hand challenged network engineers to research newer routing algorithms which satisfy the needs of these applications. In this paper we investigate various routing algorithms proposed for MANETs and the inherent problems which drive the development of these schemes.
