Abstract

[In this chapter, we introduce the proposed broadcast protocol for multi-hop CR ad hoc networks, BRACER. There are three components of the proposed BRACER protocol: (1) the construction of the broadcasting sequences; (2) the distributed broadcast scheduling scheme; and (3) the broadcast collision avoidance scheme. We assume that a time-slotted system is adopted for SUs, where the length of a time slot is long enough to transmit a broadcast packet [1]. In addition, we assume that the locations of SUs are static. We also assume that each SU knows the locations of its all 2-hop neighbors. We claim that this is a more valid assumption than the knowledge of global network topology. We provide a detailed discussion on this issue in Chapter 3.3. In the rest of the book, we use the term “sender” to indicate a SU who has just received a message and will rebroadcast the message. In addition, we use the term “receiver” to indicate a SU who has not received the message. The notations used in our protocol design are listed in Table 3.1.]
