| Abstract(in English) | In simulations of wireless ad hoc networks, numerous number of packet reachability checks are needed to consider the effect of traffic of beacons which are sent periodically from all nodes. The reachability checks can be executed in parallel. Despite recent trends of general-purpose computing on graphic processing units (GPGPU), only a few cases of using GPGPU for wireless ad hoc network simulation are reported. We designed and implemented an enhancement of a Java-base wireless network simulator JiST/SWANS for using GPGPU to check the packet reachability in parallel. The experiment results show that our implementation of parallel reachability check based on the simplest node management scheme LinearList in Jist/SWANS achieves 3.4 times and 4.9 times faster than the original JiST/SWANS's LinearList when the number of nodes is 500 and 1000 respectively. It also outperforms two efficient node management schemes Grid and HierGrid in JiST/SWANS when the number of nodes is 1000 and over. |
