A mobile ad hoc network is a multi-hop, centerless and ad hoc network consisting of a group of mobile terminals with wireless communication transceiver devices, and it does not require the support of fixed facilities, composed of a large number of dispersed wireless nodes. Each node can act as both a terminal and as a router, which means that each node can serve as a terminal to produce or receive data information and also serve as a router to forward the data information from other nodes. As the mobile terminals are mostly battery-operated and extremely sensitive to energy consumption, it is very important to prolong the lifetime of the network by reducing the energy consumption of the node. In this paper, a mobile ad hoc network is introduced briefly first, followed by the analysis of the research status of the AODV protocol for the mobile ad hoc network, with focus placed on the introduction to a routing protocol MTTC-ADOV (Minimum Total Transmission on Cost AODV) that can optimize energy consumption by choosing the routing path involving the minimum total transmission cost from all possible routing sets, with consideration given to power and node energy consumption as the routing selection goal. The total transmission cost includes the energy consumption of nodes on the link during transmission, energy consumption of nodes during the message receiving process and energy consumption of nodes during the message transmission process.The MTTC-AODV protocol required the minimum transmission power of each hop on the multi-hop link consisting of the routing, thereby extending the network lifecycle.
