项目摘要

With the growing interest in various wireless networks, the need for seamless integration and efficient transmission of heterogeneous wireless networks is becoming increasingly important. In heterogeneous wireless networks, communication between pair of a sensor and a mesh node may be asymmetric, meaning that the sensor may receive data from the mesh node but not vice versa. In this research work, we focus on the asymmetric multicast communication and propose a multicast over tree-based routing (mTBR) protocol to improve the performance of conventional protocol in terms of routing overhead, packet delivery ratio, and delay. We evaluate the proposed mTBR through simulation and verify its performance using the experiment of heterogeneous wireless networks, which consists of 802.11b/g (Wireless LAN networks) and 802.15.4 (sensor networks).

随着人们对各种无线网络的兴趣日益增长，对异构无线网络的无缝集成和高效传输的需求变得越来越重要。在异构无线网络中，传感器和网格节点对之间的通信可以是不对称的，这意味着传感器可以从网格节点接收数据，但反之亦然。在这项研究工作中，我们专注于非对称多播通信，并提出了一个基于树的路由多播（mTBR）协议，以改善传统协议的路由开销，数据包投递率和延迟方面的性能。我们评估建议mTBR通过仿真和验证其性能的实验异构无线网络，其中包括802.11b/g（无线局域网网络）和802.15.4（传感器网络）。
