碩士 === 淡江大學 === 電機工程學系碩士在職專班 === 97 === In the Ad-hoc On-Demand Distance Vector (AODV) wireless network, any two mobile nodes could transfer data to each other. It allows these mobile nodes to route the data through their neighbors to nodes with which they cannot directly communicate. However, battery capacity for mobile nodes is a very critical issue. Therefore, how to design power saving mechanisms to improve the overall survival time of AODV network is the most important topic. Conventional “Layer 3” Ad-hoc routing algorithms typically make routing decisions based on the minimum hop-count (MHC). In the real world, the node is restricted with the battery capacity. Use of the MHC metric leads to selection of paths with few hops but one or more of these hops may turn out to be low-speed radio links and waste more transmission power due to adaptive rate selection at the physical layer. In this thesis, a new cross layer routing metric algorithms has been studied. It is called, Cross Layer Routing Protocol (CLAP) for AODV wireless network with Power Aware and Multi-rate (CLAP-AODV). CLAP-AODV finds routing paths that maximize the lifetime of network and minimize the total transmission energy consumption. Design and implementation of the proposed CLAP-AODV metric for proactive ad-hoc routing protocols are also presented. Simulation results for typical ad-hoc network scenarios show that the proposed CLAP-AODV metric achieves significantly maximize the lifetime and the high-speed radio link of network by selecting paths.
