Overview

The three routing protocols AODV, OLSR and ZRP have been introduced in this section. AODV and OLSR are both accepted as experimental RFCs by the IETF and they are probably the two most popular MANET routing protocols at the current time. Much research and work is being done using these protocols. The hybrid ZRP protocol has not gained that much popularity. The protocol is actually more of a framework than a routing protocol, and it relies on well defined and robust routing protocols to be utilized in and between the zones. The latest ZRP Internet draft expired January 2003, but work is still said to be done by the authors and others. The need for solutions like ZRP might arise when the basic protocols are well tested and their limitations have been proven.
