Abstract

Open Shortest Path First (OSPF) is a well known and prominent Internet Protocol (IP) for network routing. By deploying a link state routing (LSR) algorithm OSPF comes under the category of interior gateway routing protocols. In today’s wireless ad hoc Internet, the current routing domain needs to maintain a peak level of service accessibility and availability, thus OSPF must be extended to the wireless ad hoc network for maximizing routing performance in the network by taking into account key routing issues, i.e., optimal Hello Interval, efficient flooding schemes, optimizing the traffic engineering related issues, optimum adjacency creations, connectivity factors, reducing control overhead, and QoS and security challenges. In addition, OSPF is very effective in its adoption of handling the network bandwidth utilization, therefore, wireless capacity planning is of utmost importance for today’s Internet with the possible presence of wireless infrastructure. Improving routing stability in OSPF MANET under topology change(s) due to variation in link connectivity becomes a very demanding challenge for the research community. Given a fascinating volume of review for literature and unavoidable importance relating to OSPF extension to MANETs, there has still persist a need to highlight key issues related with routing in OSPF MANET.
