Based on Third Generation HF Wireless Communications Routing Design

摘要

Routing is one of the key technologies of the Third Generation HF wireless communication network, and is the hotspot of the research in the field at present. This paper proposes a minimum energy cost link cache dynamic source routing protocol MECDSR (An On-demand Minimum Energy Cost Routing Protocol) based on the traditional DSR protocol. This routing protocol mainly uses the "five ideas" to improve the DSR: the idea of transmission power control, the idea of minimum energy consumption, the idea of link cache, the idea of short path and the idea of seeking minimum energy consumption by real-time tracking based on the data piggyback technology. Simulate on the HF communication network model which is composed by twenty-five communication nodes, and the simulation results show that, compared with the traditional DSR ,the MECDSR can averagely delay the death time of the first node by 2 times, and extend the entire communication network 's life cycle by 1.26 times. Therefore, the MECDSR is more suitable for Third Generation HF Wireless Communications networks in energy efficiency and the improvement of the network's lifetime.
