A Survey on Geographic Routing Protocol in MANET

Anand Gautam, Shiva Prakash


Mobile ad hoc networks (MANET) are characterized by multi-hop wireless links and resource constrained nodes. One of the
major challenges in mobile ad hoc networks (MANETs) is link failures due to mobility. Because nodes in a MANET act as
routers for any ongoing packet communication and have limited transmission ranges, the communication links are broken, and
packet losses occur. To improve network lifetime, energy balance is an important concern in such networks. Geographic
routing has been widely regarded as efficient and scalable. However, it cannot guarantee packet delivery in some cases, such as
faulty location services. The matter gets even worse when the nodes on the boundaries of routing holes suffer from excessive
energy consumption, since geographic routing tends to deliver data packets along the boundaries by perimeter routing. This
paper will be a basis for study in the domain of geographic routing for the new researcher point of view.
