Study and analysis of opportunistic routing protocols in MANET

Mobile Ad-hoc Network (MANET) is a self-configuring infrastructure less network of wireless communication. The performance of MANET fundamentally depends upon routing protocols used by the network. MANETs are typically powered by batteries which have limited energy reservoir and it may not be easily replaced or recharged on the way. Hence, power consumption becomes an important issue. Opportunistic routing has recently emerged as a mechanism for obtaining high throughput even when links are lost. The opportunistic routing allows any node that overhears the transmission and is closer to the destination to participate in forwarding the packet. In this paper, we compare the Opportunistic Routing Protocols such as EXOR, MORE, SOAR, POR and PSR. The simulation of opportunistic routing is provided based on Quality of Service (QoS) and energy efficiency in MANET.
