ODMA网络高效路由修复算法研究

ODMA（Opportunity Driven Multiple Access）是一种全IP式智能、交互式自组网技术,具备高速移动接入、智慧选径等特点。针对ODMA网络节点在高速移动中可能造成的通信断链,同时考虑到现有路由修复算法的局限性,文章以本地修复机制为基础,提出一种适用于ODMA网络的改进型AODV路由算法（OW-AODV）。该算法将修复过程尽可能限制在断链的“下二跳”范围内,同时进一步细化相关路由报文,并规定相应的处理策略。仿真结果表明,OW-AODV可在控制开销指标的同时,有效提高ODMA网络的数据投递率及路由修复效率。...

Summary:ODMA（Opportunity Driven Multiple Access）是一种全IP式智能、交互式自组网技术,具备高速移动接入、智慧选径等特点。针对ODMA网络节点在高速移动中可能造成的通信断链,同时考虑到现有路由修复算法的局限性,文章以本地修复机制为基础,提出一种适用于ODMA网络的改进型AODV路由算法（OW-AODV）。该算法将修复过程尽可能限制在断链的“下二跳”范围内,同时进一步细化相关路由报文,并规定相应的处理策略。仿真结果表明,OW-AODV可在控制开销指标的同时,有效提高ODMA网络的数据投递率及路由修复效率。

ODMA （Opportunity Driven Multiple Access）is the next-generation IP intelligent and interactive Ad hoc network system with characteristics such as wisdom path selection and high-speed mobile access. In order to repair the broken link caused by high-speed mobile ODMA nodes and overcome the common shortcomings of some existing routing algorithms, this paper proposes an improved AODV local-repair algorithm （OW-AODV） which classifies various route requests and route reply messages according to the predetermined flag and then takes the corresponding processing strategies. The simulation analysis shows that OW-AODV can control the overhead indicators, as well as signifi- cantly improve data delivery ratio and route repair efficiency of ODMA networks.
