Title: Multihop radio communication network, mobile node, and communication method
Inventor: FUJII TAKEO
IPC: H04W84/18
Filed: 2008-07-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a multihop radio communication network which suppresses radio wave interference and optimizes data transfer efficiency.  <P>SOLUTION: Each of mobile nodes selects a subcarrier to be used for data transmission, calculates the number of transmittable bits in a 10 FDM symbol based on radio communication quality between the mobile node and a mobile node at a transfer source, and the mobile node at the transfer source determines fixed packet length based on the number of transmittable bits in the 10 FDM symbol between mobile nodes with the lowest transmission capacity in a transfer path. Each mobile node determines time slots with different transmission timing from that of the adjacent mobile node and transfers data comprising the fixed packet length. When the minimum necessary subcarrier is selected, in the case where the subcarrier of the mobile node overlaps a subcarrier in the hop after the next one in the transfer path, the subcarriers on the side with the more number of transmittable bits in the 10 FDM symbol are reduced.  <P>COPYRIGHT: (C)2010,JPO&INPIT
