2.6 Summary
This chapter has described the different types of ad hoc routing protocols. With examples of
each type as well as mentioning the main concepts, advantages and disadvantages of each.
The proposed work in this thesis uses the recursive unicast method to implement the
multicast routing, so there is a need for underlying unicast routing protocol to be used. The
selection of AODV to be the underlying routing protocol is done as this protocol gives a
reliable and efficient tree based routing.
These mentioned protocols are considered as a state scheme protocols, because these
protocols keep routing information inside the routers. The following chapter will discuss
different type of wired and ad hoc protocols, explicit multicast protocols that were proposed
to reduce the state routing information kept and move towards reducing the state information.
