Broadcast or flooding is a dissemination technique of paramount importance in wireless adhoc networks. The broadcast scheme is widely used within routing protocols by a widerange of wireless ad hoc networks such as mobile ad hoc networks, vehicular ad hoc networks,and wireless sensor networks, and used to spread emergency messages in criticalscenarios after a disaster scenario and/or an accidents. As the type broadcast scheme usedplays an important role in the performance of the network, it has to be selected carefully.Though several types of broadcast schemes have been proposed, probabilistic broadcastschemes have been demonstrated to be suitable schemes for wireless ad hoc networksdue to a range of benefits offered by them such as low overhead, balanced energy consumption,and robustness against failures and mobility of nodes. In the last decade, manyprobabilistic broadcast schemes have been proposed by researchers. In addition to reviewingthe main features of the probabilistic schemes found in the literature, we also present aclassification of the probabilistic schemes, an exhaustive review of the evaluation methodologyincluding their performance metrics, types of network simulators, their comparisons,and present some examples of real implementations, in this paper.
