Abstract


Wireless mobile ad hoc network technology (Ad hoc), compared with the traditional wired network, by means of mobile nodes and wireless communications equipment dynamically generate a new generation of network. Its nodes rely mainly on battery supply, energy efficient and increase network throughput to become a major research direction. The main work of this paper include: Ad hoc network and its power control technology analysis based on in-depth study of three technical issues encountered in the power control of wireless Ad hoc networks: transmission power control, power routing, low-power mode be discussed, with an emphasis on the transmission power control and propose a new power control scheme jointly decided by the MAC layer and the network layer, which performs two functions, improve network throughput and reduce the energy consumption of nodes, improve network throughput. energy consumption of respective nodes on the basis of the amount reduced. It features: First, the nodes within the region classification similar transceiver nodes use the same power, this power is the relative power, and avoid the use of the maximum power, which can reduce the energy consumption of each node, again in the different classes between nodes different power transceivers, the above highlights can be provided for large area node, node power of different sizes, to avoid the all-pass network is to be formed in the entire region using the maximum power, may also have a bidirectional link to eliminate the hidden terminal problem. Better compatibility In addition to this agreement, majority agreement calls for the network to have full continuity and bi-directional link. And this article using a the channel proxy methods simplified protocol difficulty, for similar nodes use the same power the different classes of nodes of the same channel using different channels of different power, the different categories of the node information exchange via the channel agent finishes. Classification of nodes can be divided into three. : Node roughly evenly distributed, according to the area classification: key node network, according to key nodes distinguish reduce bottlenecks. : Clustered node, according to the bulk density of distinction. According to the classification of different a different conclusion, the idea of ??using the limit, if the entire area is a group, then the whole area is only a maximum power, and if each node is a group then each node is a channel proxy node. In this paper, the first case. Last by using OMnet software to establish a simulation model from the physical layer to the application layer, prove that the agreement may be well with existing 802.11 physical layer and MAC layer, AODV routing protocol combining simulation found that the agreement greatly improved network performance.
