Um protocolo de controle de acesso ao meio de salto de canal (MAC) é proposto para operação cognitiva das redes Mesh 802.16d. A proposta inclui principalmente um algoritmo de salto de canal de acesso a canais para transmissão e recepção de mensagens de controle, um algoritmo de alocação de largura de banda em operação cognitiva, uma estrutura de quadro aprimorada por cognição, um método de relatório de resultados de detecção de espectro e um método de detecção incumbente. Comparado a outros estudos, o algoritmo de salto de canal para transmissão e recepção de mensagens de controle não requer canais de controle comuns extras e operação de clusters de malha, portanto, é mais econômico e mais simples de operar. A análise mostra que com este algoritmo um nó Mesh com quaisquer canais disponíveis tem oportunidades justas de receber beacon e informações de configuração de rede. Os resultados numéricos mostram que, comparado ao método de cluster em malha, o algoritmo de salto de canal proposto tem ganho, por exemplo, tão alto quanto 3 vezes, na obtenção de mensagens de controle de escalonamento de dados recebidas por vizinhos de um salto, portanto, tem vantagens em minimizar a largura de banda colisões de alocação. O algoritmo de alocação de largura de banda detalha a estrutura de handshake de três vias para aplicação e concessão de largura de banda definida no padrão Mesh 802.16d e permite alocações dinâmicas de recursos em operações cognitivas. A viabilidade do protocolo MAC de salto de canal é confirmada por simulações. E os resultados da simulação mostram que, com os parâmetros definidos, é possível obter uma taxa de transferência de saturação agregada normalizada de cerca de 70%.

Abstract: A channel-hopping medium access control (MAC) protocol is proposed for cognitive operation of the 802.16d Mesh networks. The proposal mainly includes a channel-hopping algorithm of channel accessing for control messages transmission and reception, an algorithm of bandwidth allocation in cognitive operation, a cognition-enhanced frame structure, a method of spectrum sensing results reporting, and a method of incumbent detection. Compared to other studies, the channel-hopping algorithm for control messages transmission and reception requires no extra common control channels and operation of mesh clusters, thus it is more cost-effective and simpler in operation. Analysis shows that with this algorithm a Mesh node with any available channels has fair opportunities to receive beacon and network configuration information. Numerical results show that, compared to the mesh cluster method, the proposed channel-hopping algorithm has gain, e.g., as high as 3 times, in getting the data scheduling control messages received by one-hop neighbors, thus it has advantages in minimizing bandwidth allocation collisions. The algorithm of bandwidth allocation details the three-way handshake framework for bandwidth application and grant that is defined in 802.16d Mesh standard, and it enables dynamical resource allocations in cognitive operations. The feasibility of the channel-hopping MAC protocol is confirmed by simulations. And simulation results show that with the parameters set, a normalized aggregate saturation throughput of about 70% is achievable.
