Alocação de canais para redes veiculares baseada no comportamento do nó

Abstract

This work presents a node behavior-based channel allocation strategy for Vehicular Ad hoc NETworks (VANETs). The main contribution of this work is to consider some characteristics of the node behavior to guide the channel allocation process in VANETs. In the work is used a distributed approach that allows the strategy quickly to respond to changes in the network topology while limiting the exchange of messages. The channels allocated are of the spectrum of the IEEE 802.11p standard and the evaluation metrics are: throughput, packet delivery rate, end-to-end delay, and overhead. The results show that the strategy presents higher aggregated throughput and packet delivery rate, with lower end-to-end delay when compared to random channel allocation method and single channel. When compared to a centralized approach, the strategy presents performance closer to Tabu algorithm, but with lower overhead.
