Scheduling Algorithm for Vehicle to Road-Side Data Distribution [chapter]

Mohammad Shahverdy, Mahmood Fathy, Saleh Yousefi
2010 Communications in Computer and Information Science  
We propose a scheduling algorithm in which each RSU implements two separate queues for: 1) download requests from the scratch and 2) resumed downloads.  ...  The data segment for distribution is chosen from aforementioned queues based on some scheduling policies.  ...  Performance Evaluations Experimental Setup We simulate our proposed algorithm with ns-2 [13]. The simulation area is a 400*400 square that includes 9 cross-roads.  ...
