Wireless communication system, wireless communication device, method of wireless communication, and computer program

Abstract

Provided is a wireless communication system, wireless communication device, method of wireless communication, and computer program to stably execute the route control as a sequence at the beginning of communications in an self-organization network and enable a stable communication. A terminal of a packet sending source forms an expanded route request message, containing a key exchange request message in a route request message, and sends it by broadcasting toward an addressed terminal to deliver it to the addressed terminal, in accordance with a specified route setting process. The addressed terminal having received the expanded route request message forms an expanded route answer message including a key answer request message in the route answer message, and establishes a route reverse to the send source terminal to send it by unicast.

Description

technical field [0001] The present invention relates to a wireless communication system, a wireless communication device, a wireless communication method, and a computer program for communicating with each other among a plurality of wireless stations, and in particular to a device that is not specially configured as a control station through self-organization (Ad- hoc) communication to construct a wireless network, a wireless communication device, a wireless communication method, and a computer program. [0002] More specifically, the present invention relates to a wireless communication system, a wireless communication device, a wireless communication method, and a computer program that perform path control as a sequence at the start of communication in an ad hoc network (mesh network or multi-hop network), especially The present invention relates to a wireless communication system, a wireless communication device, a wireless communication method, and a computer program that ...

AI Technical Summary

Problems solved by technology

However, since the encryption key generation process of these key exchange protocols is usually performed after the path is created, there is a problem that it takes time before communication starts.

In addition, control messages for path control and key exchange are frequently generated, thereby increasing the number of times message processing and communication traffic on the terminal become loads.
