Comparative Analysis of OLSR and GRP Routing Protocols in Mobile Ad-Hoc Networks

Wireless Technology is at its pinnacle. This field of MANET'S has become a hub of invention of latest theories and structures. Mobile Ad-hoc Network may be a special purpose of focus for the researchers. Mobile Ad-Hoc Networks (MANETs) are autonomous and decentralized wireless systems. Mobile Ad hoc Network may be a agglomeration of mobile nodes within which the wireless links are often broken because of mobility and dynamic infrastructure. Routing may be a broader issue and challenge in Mobile ad hoc networks. The main categorization of MANET routing protocols are Proactive, Reactive and Hybrid. Formulating this paper our objective is to compare performance of various routing protocol in particular Geographical-based Routing Protocol (GRP) which is a hybrid protocol and Optimized Link State Protocol (OLSR) which is a proactive routing protocol, whereby routes mostly discovered and updated frequently and accessible on demand. The simulation results showed by various researchers has been reviewed and comparison of these routing protocols has been presented on the basis of performance parameters such as throughput, delay, load, etc.
