虚电路技术可以为Ad Hoc网络中的节点提供面向连接的服务。然而,由于拓扑动态性等特征,Ad Hoc网络中的虚电路容易断开,从而导致业务时延、时延抖动增大甚至通信中断等问题。为此文章提出了一种基于弱多径覆盖的虚电路恢复策略,通过将虚电路机制与弱多径覆盖多径策略相结合,可以有效地减少虚电路恢复时间和需要重新预约资源的节点的数量。理论分析和仿真结果表明了该方法的有效性。
Virtual circuit technology can provide connection-oriented services for nodes in Ad Hoc networks. However, because of topological dynamic characteristics, virtual circuits in Ad Hoc network can be easily disconnected, resulting in problems such as service delay, delay jittering and even communication interruption. This paper proposes a virtual circuit recovery strategy based on weak multipath coverage. By combining the virtual circuit mechanism with the weak multipath coverage multipath strategy, the virtual circuit recovery time can be effectively reduced and the nodes that need to reserve resources again Quantity. Theoretical analysis and simulation results show the effectiveness of this method.
