Abstract: To solve the redundancy of control overhead and allocation time consumption in the address assignment algorithm of Low-Rate Wireless Personal Area Network (LR-WPAN) mesh, a High-efficiency and Low-delay Address Assignment (HLAA) algorithm for LR-WPAN mesh was proposed. By using the process of network access to realize the function of network access and address assignment, and deleting the redundant fields in the address assignment, HLAA had reduced allocation time as well as control overhead in the premise of realizing the function of address allocation. The simulation results show that compared with the original algorithm, HLAA can decrease the control overhead by 22.15%, and reduce the allocation time by 7.68%.

摘要： 针对IEEE 802.15.5标准中低速率无线个域网(LR-WPAN) Mesh的地址分配算法在地址分配通信开销和时间方面存在冗余的问题,提出一种高效低时延的地址分配(HLAA)算法。该算法通过使用入网申请消息替代专门的地址申请消息和删除地址分配消息中的冗余字段,减少了通信开销并降低了组网时延。仿真结果表明:与现有的低速率无线个域网地址分配算法相比,HLAA算法的通信开销减小了22.15%,组网时延则降低了7.68%。
