“…Many communication mechanisms have been introduced in WMN including link scheduling , gateway placement , gateway selection , relay selection , broadcast routing , and multicast routing to support its applications. A vital question in all these designing issues is how to assign the available channels to interfaces of nodes in such a way that the minimal interference is achieved.…”

Wireless mesh network (WMN) has been deployed as a key and progressing technology all around the world to provide the end-to-end users with high quality of service. Regarding of its major design concern as network throughput, WMN has been evolved based on multi-channel multi-radio strategy to make simultaneous transmissions possible. The advent of this significant improvement has introduced other challenging issues such as channel assignment (CA). Its core strategy applied in multi-radio multi-channel WMNs to promote achievable capacity using properly mapping the available channels to the radio interfaces. Although, in recent years, there are a number of research studies on CA's improvement, there are some security drawbacks that should be addressed. Most of CA schemes assume all nodes involved in CA techniques are trustworthy. This unrealistic assumption and misbehavior of those nodes makes the network susceptible to various security attacks which lead to performance degradation. This paper presents an in-depth survey of the CA's attacks as well as detection or prevention mechanism found in the literature. The attacks are classified into two groups: attacks imposed by the malicious neighbor as well as by the assigner or the assignee. In addition, a comparative and analytical discussion is provided on current solutions and their open problems. According to conducted analysis, the current knowledge gap leading to most of these attacks is lack of accurate verification because of implicit trust in nodes in CA procedure. Although, there are some research studies proposing kinds of case-specific verification, they cannot close the gap properly, and there is a need to comprehensive approach. Finally, reviewing state-of-the-art of related works shows, there are more possible attacks such as collusion or multistage attacks that have not taken into account so far.

“…In ACCPF, nodes take into account both the Euclidean distance and the number of copies received in order to compute the forwarding probability (68). In this scheme, each node maintains the number of copies m, and the smallest additional coverage area S min for each broadcast packet m. After a waiting period of time RAD, the nodes retransmit with a probability,…”

a b s t r a c tBroadcast or flooding is a dissemination technique of paramount importance in wireless ad hoc networks. The broadcast scheme is widely used within routing protocols by a wide range 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 critical scenarios after a disaster scenario and/or an accidents. As the type broadcast scheme used plays 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 broadcast schemes have been demonstrated to be suitable schemes for wireless ad hoc networks due 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, many probabilistic broadcast schemes have been proposed by researchers. In addition to reviewing the main features of the probabilistic schemes found in the literature, we also present a classification of the probabilistic schemes, an exhaustive review of the evaluation methodology including their performance metrics, types of network simulators, their comparisons, and present some examples of real implementations, in this paper.
