摘要

In Ad Hoc networks with the hierarchical architecture, the communications for the Source-Destination pair belonging to the different Clusters often traditionally employ the triangle loop routing mode, and the communication data should be forwarded through the attached Cluster headers and serious system overhead is caused. An alternative strategy is establishing a direct routing for the Source-Destination pair, but is not always the optimal one. To address this issue, with the aid of the locations of the Source-Destination pair, the system overheads caused by the triangle loop routing mode and the direct routing mode is firstly analyzed and modeled, an improved communication scheme (adaptive routing optimization) then is proposed, which can dynamically adjust the routing mode for different system objectives. By respectively taking the energy consumption and communication delay as the main system objective, an Ad Hoc network with multi-hierarchy architecture is conducted on the NS-2 simulation platform, and the effectiveness of the adaptive routing optimization is verified by adjusting the deployed hierarchy number and the routing distance for the Source-Destination pair.
