基于应急场景的自组织网络机会路由算法
An Opportunistic Routing Algorithm Based on Emergency Scenario in Ad Hoc Networks
摘要
Abstract
Emergency scenario is an important application scenario of Ad Hoc Networks. In this scenario,it is difficult for nodes to ensure the communication. It becomes one of the goals that forwarding data packet efficiently while minimizing the transmission delay. A new opportunistic routing algorithm based on stability value is proposed,introduction of the concept of stable factor in it that the movements of nodes are associated with their neighbors. The node which has better stability is prone to receive the data packet. Moreover,with regard to the dynamics and complexity of the emergency scenario,the algorithm will dynamically update the stability of the nodes. According to simulation results,compared with the traditional routing algorithm like Epidemic,Direct Delivery,Prophet,the proposed algorithm suitable for emergency scenario can reduce the overhead and improve the delivery ratio in different network scales.关键词
