A mixed topology control method based on AODV protocol

Abstract

A mixed topologic control method improving route protocol performance and system integral performance combines with AODV protocol. The technical solution is that method comprises an area division, a topologic control in an area and a topologic control among areas, characterized in that further comprises steps of improving AODV route protocol; adding two control messages POSITION and POWER in the AODV route protocol, respectively to send the topologic information to a central node by a node in the area and to send the power configuration information to each corresponding node by the central node, adding corresponding message sending and receiving function as well as a timer to carry out the topologic control; on another hand, mending a Hello message format and process flow of AODV and solving single way channel problem that could occur after topologic control and carrying out distributing control.

Description

technical field [0001] The invention belongs to the field of wireless Ad hoc network topology control methods, in particular to a hybrid topology control method combined with the AODV protocol for solving the problems of wireless Ad hoc network capacity, interference, energy, connectivity and routing. The invention has no strict limitation on the network scale, and is especially suitable for tactical cooperative communication in the military field and static Ad hoc networks, such as wireless sensor networks. Background technique [0002] Topology control is one of the important technologies of wireless Ad hoc network research in recent years. Topology control is to adjust the signal transmission power under the condition of ensuring a certain communication quality, and finally make the nodes form a fully connected network with the minimum transmission power. Through topology control, not only can save battery energy, prolong the life of nodes, simplify the network topology,...
