Wireless multi-hop network data sending and receiving methods based on intelligent antenna technology

Abstract

The invention is applied to the wireless mobile communication field, and provides wireless multi-hop network data sending and receiving methods based on intelligent antenna technology. The data sending method comprises the following steps: (a1) acquiring destination address information from a data packet to be sent; (a2) according to the acquired destination address information, determining a destination node in all overlay nodes overlaid by an emission node; (a3) according to the determined destination node and other overlay nodes overlaid by the emission node, determining an expectation angle and an interference angle; (a4) according to the determined expectation angle and the interference angle, calculating a weight vector of adaptive wave beamforming , and aligning a main lobe with an expectation signal and aligning a zero point with an interference signal; (a5) according to the weight vector of the adaptive wave beamforming, sending the data packet after weighted to the object node. According to the sending method in the invention, a node coverage range, communication quality and communication efficiency can be raised, and a communication blind area can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of wireless mobile communication, in particular to a wireless multi-hop network data sending and receiving method based on smart antenna technology. Background technique [0002] Today's information society is entering the Internet age from the era of personal computers.
