Abstract
Topology control has received much attention in stationary sensor networks by effectively minimizing energy consumption, reducing interference, and shortening end to-end delay. The transience of mobile nodes in Vehicular Ad hoc A network (VANETs) renders topology control a great challenge. the existing edge connected topology control algorithms need to determine the value priori, but moving speeds of nodes are unpredictable, and therefore, these algorithms are not practical in VANETs. In the proposed method if node failure occurs the described algorithm automatically determines the appropriate alternate node based on the efficient values for the required graph, using Local information while ensuring the required connectivity ratio of the whole network. The results show that the dynamic method can enhance the practicality and packet transmission in undisturbed channel with the strong topology control algorithms while guaranteeing the network connectivity.
