异构自组织网络环境下路由算法研究

摘要

针对传统自组织网络路由方法不能满足异构网络环境下的通信要求这一问题，提出混合节点发现算法（HNDA ）以及结合路由跳数和节点负载的综合度量方法（CM‐HCTL）；将HNDA与CM‐HCTL相结合融入AODV协议，得出完整的异构网络环境下自组织网络路由解决方案 HC‐AODV。对AODV和 HC‐AODV这两种算法进行仿真对比，仿真结果表明，在一定的网络环境下， HC‐AODV 方法能够提高数据分组投递率，降低平均端到端时延以及路由控制开销，具有有效性。%To solve the problem that the traditional self‐organizing network routing method is unable to meet the communication requirements in heterogeneous network environment ,a hybrid nodes discovery algorithm (HNDA) and a comprehensive‐metric method combining hop count with traffic load (CM‐HCTL) were designed .And a complete self‐organizing network routing solu‐tion (HC‐AODV) in heterogeneous network environment based on the combination of HNDA and CM‐HCTL in AODV was pro‐posed .The results of computer simulations show with the usage of HC‐AODV method in the certain network environment , packet delivery ratio can be improved ,and both average end‐to‐end delay and routing control overhead can be reduced .In conclu‐sion ,the effectiveness of the HC‐AODV is demonstrated .
