Description
Summary:The Vehicular Ad-hoc NETwork (VANET) requires a suitable routing protocol to accommodate its special characteristics (e.g., high mobility, short-lived links, and fast-changing topology). There are many routing algorithms which are developed for transmitting information more quickly and cost-effective. In this paper, we propose a routing protocol which relies on Defer-Time Control Function (DTCF) to reduce the hop count, the transmission delay, and the probability of collisions during transmission. We provide an extensive analysis of DTCFs and choose the power-law model for routing protocol optimization. The function can be adjusted dynamically according to the distribution of the neighboring nodes (vehicles) of each hop. We also propose a mechanism to prevent the selected next-hop leaves the transmission range.
