Embodiment Construction

[0035] This embodiment discloses a wireless terminal design method with a routing function, including the following steps:

[0036] A wireless terminal design method with routing function, which is to build a wireless self-organizing network hardware terminal on the ARM Linux platform, use Samsung s3c2410 processor to connect to the wireless network card supporting 802.11a / b / g, plus SDRAM, Nand The modules of flash, debugging serial port and power supply constitute the hardware framework of the wireless terminal. On this basis, the Bootloader, Linux kernel, file system and AODV routing protocol are transplanted. In order to demonstrate the functions of routing protocols more conveniently, iptables is transplanted at the same time. The entire wireless terminal device with routing function realizes the demonstration of routing jump and self-organization function on the basis of 802.11a / b / g, and at the same time encapsulates the hardware circuit board to form a wireless terminal...

Abstract

The invention relates to a method for designing a wireless terminal which can realize data wireless transceiving and has a routing function. The method comprises the following steps of: establishing a mobile ad hoc network hardware terminal on a random access memory (ARM) Linux platform; connecting a wireless network card supporting 802.11a / b / g by using a Samsung processor s3c2410; and arranging modules such as a synchronous dynamic random access memory (SDRAM), a Nand, a flash, a debugging serial port and a power supply to obtain a hardware framework of the wireless terminal. On the basis, Bootloader, a Linux kernel, a file system and an ad hoc on-demand distance vector (AODV) routing protocol are transplanted. In order to more easily demonstrate the function of a routing protocol, iptables is also transplanted. Based on the 802.11a / b / g, the whole wireless terminal equipment having the routing function realizes the demonstration of route jump and a self-organization function, and a hardware circuit board is packaged to form the wireless terminal equipment having the routing function.

Description

technical field [0001] The invention relates to a design of a wireless terminal with a routing function, especially realizes wireless self-organization and routing and forwarding functions, and belongs to the technical field of wireless communication. Background technique [0002] There are three mainstream standards for wireless LAN, 802.11a / b / g. The 802.11b specification works in the 2.4GHz communication frequency band, the data rate exceeds the critical limit of 10Mbps, and the physical layer adopts high-speed direct sequence spread spectrum technology. The second branch of 802.11 is 802.11a. 802.11a operates in the 5.2GHz frequency band and is specified for data rates up to 54Mbps. And 802.11g can provide the same 54Mbps connection rate as the 802.11a standard when it is compatible with the 802.11b network. [0003] The wireless network cards currently available on the market simply support the Infrastructure mode, and few products support the AdHoc mode. Even if it i...
