The basic idea of DBT [5] was proposed without any actual implementation and simulation
study. In our first part of research a modification was made to the previous proposed protocol
and implemented in addition to comprehensive simulation study.
The remainder of this chapter is organized as follows; Sections 4.3 to 4.5 will explain SReM
protocol and its details while at Section 4.6 the implementation and results will be discussed
in Section 4.7.
4.2.1 Definitions
In this section, definitions of terminologies and messages used in the proposed protocol are
explained. These messages and terminologies will be discussed in details during the
explanation of the proposed protocol in this chapter, which are summarized in Table 4.1.

The proposed protocol uses a set of messages for constructing and maintaining the multicast
tree. Table 4.2 summarizes these messages used in the proposed protocol.
