ExOR - Extremely Opportunistic Routing

Jump to navigation Jump to search

Description

Extremely Opportunistic Routing is a Routing algorithm that takes advantage of the characteristics of wireless networks. Therefor ExOR determines the path as the packet moves through the network instead of choosing a single route ahead of time.

Implementation

Performance

In comparison to many well-known Routing - algorithms like OSPF,DSR,AODV Opportunistic routing generally performs better than the a margin of 55%. Depending on how large the network is there are improvements of up to 65%. In generell the greatest benefit out of ExOR is its ability to skip intermediate hops.
