O protocolo Medium Access Control (MAC) que utiliza múltiplos canais não sobrepostos, denominado protocolo MAC multicanal, foi proposto com o objetivo de aumentar a capacidade das redes ad hoc. Como o número de interfaces de pacotes em cada nó é menor que o número de canais em redes ad hoc em geral, o nó precisa selecionar um canal adequado para transmissão de dados. Isso significa que o protocolo MAC multicanal deve ser fornecido com um bom algoritmo de seleção de canal. Neste artigo, projetamos um algoritmo de seleção de canal denominado Seleção de Canal Aleatório Condicional (CRCS) baseado no protocolo Extended Receiver Directed Transmission (xRDT) que usa apenas uma interface de pacote. Resumidamente, o CRCS utiliza o canal ativo para transmissão de dados até que a quantidade de pacotes de dados atinja um limite, momento em que seleciona um dos canais disponíveis, diferente do canal ativo. Embora o CRCS seja um algoritmo de seleção de canais muito simples, ao usar o simulador de rede descobrimos que o CRCS é eficaz para aumentar a capacidade de redes ad hoc e para manter o equilíbrio de carga de todos os canais em comparação com outros algoritmos de seleção de canais.

Abstract: The Medium Access Control (MAC) protocol that uses non-overlapping multiple channels, called the multi-channel MAC protocol, was proposed in order to increase the capacity of ad hoc networks. Since the number of packet interfaces on each node is less than the number of channels in ad hoc networks in general, the node needs to select a suitable channel for data transmission. This means that the multi-channel MAC protocol must be provided with a good channel selection algorithm. In this paper, we design a channel selection algorithm called Conditionally Randomized Channel Selection (CRCS) based on Extended Receiver Directed Transmission (xRDT) protocol that only uses one packet interface. Briefly, CRCS uses the acitve channel for data transmission until the amount of data packets reaches a threshold, at which point it selects one of the available channels other than the active channel. Although CRCS is a very simple channel selection algorithm, by using network simulator we find that CRCS is effective to increase the capacity of ad hoc networks and to keep the load balance of all channels compared to the other channel selection algorithms.
