Em redes entre veículos, é necessário que as mensagens de alerta de colisão sejam distribuídas em vários saltos com atraso significativamente curto. O encaminhamento de pacotes cut-through é conhecido por ser um método eficaz para reduzir a latência de encaminhamento. No entanto, sofre do problema de confiabilidade, que é especialmente grave em cenários altamente móveis, devido ao desvanecimento de múltiplos caminhos. Este artigo tenta estabelecer um esquema de encaminhamento cut-through confiável aplicando o método de combinação de diversidade a mensagens de aviso de colisão. Ao explorar a natureza do encaminhamento multi-hop de um pacote de difusão em redes sem fios CDMA, o esquema de combinação de diversidade não incorre em qualquer sobrecarga ou atraso de comunicação adicional. Os resultados da simulação mostram que os esquemas de combinação de diversidade, especialmente a combinação de razão máxima (MRC), podem efetivamente reduzir o BER em ordens de grandeza.

Abstract: In inter-vehicle networks, it is required that collision warning messages be distributed over multiple hops with significantly short delay. Cut-through packet forwarding is known to be an effective method to reduce forwarding latency. However, it suffers from the reliability issue, which is especially severe in highly mobile scenario, due to multi-path fading. This paper tries to establish a reliable cut-through forwarding scheme by applying diversity combining method to collision warning messages. By exploiting the nature of the multi-hop forwarding of a broadcast packet in CDMA wireless networks, the diversity combining scheme does not incur any additional communication overhead or delay. The simulation results show that diversity combining schemes, especially Maximal Ratio Combining (MRC), can effectively reduce BER by orders of magnitude.

AB - In inter-vehicle networks, it is required that collision warning messages be distributed over multiple hops with significantly short delay. Cut-through packet forwarding is known to be an effective method to reduce forwarding latency. However, it suffers from the reliability issue, which is especially severe in highly mobile scenario, due to multi-path fading. This paper tries to establish a reliable cut-through forwarding scheme by applying diversity combining method to collision warning messages. By exploiting the nature of the multi-hop forwarding of a broadcast packet in CDMA wireless networks, the diversity combining scheme does not incur any additional communication overhead or delay. The simulation results show that diversity combining schemes, especially Maximal Ratio Combining (MRC), can effectively reduce BER by orders of magnitude.
