Abstract

Node IDs are stored in an NAT in association with MAC addresses, and bit information indicating whether to reverse a channel allocation rule that is based on whether a node ID is an odd number or an even number is stored in a reverse register. Also, information indicating whether to use each 60G wireless module is stored in a disable register. Then, a CH determination unit allocates a channel to each 60G wireless module based on the NAT, the reverse register, and the disable register. That is, the CH determination unit allocates a channel, for the 60G wireless module to be used, based on whether the node ID is an odd number or an even number and whether to reverse the channel allocation rule that is based on whether the node ID is an odd number or an even number.

Claims

1. An information processing apparatus comprising:

an allocation unit that allocates a channel to be used for wireless communication by the information processing apparatus in a housing based on position information of the information processing apparatus in the housing in such a way that the channel is not same as a channel to be used for wireless communication in a same direction by an adjacent information processing apparatus; and

a communication unit that performs wireless communication with another information processing apparatus in the housing by using the channel allocated by the allocation unit.

2. The information processing apparatus according to claim 1,

wherein information processing apparatuses are arranged two-dimensionally in the housing, with an even number of information processing apparatuses being arranged in a first axis direction, each information processing apparatus including a plurality of the communication units,

wherein a number storage unit that stores, for respective information processing apparatuses, serial integer numbers allocated to respective information processing apparatuses sequentially from a predetermined position in the housing in the first axis direction, and after reaching an information processing apparatus at an end in the first axis direction, from another end in a level that is shifted by one in a second axis direction, and

a reversal information storage unit that stores whether a position is odd-numbered or even-numbered in the second axis direction are further comprised as the position information, and

wherein the allocation unit allocates different channels to respective communication units based on the number storage unit and the reversal information storage unit.

3. The information processing apparatus according to claim 1,

wherein information processing apparatuses are arranged two-dimensionally in the housing, with an odd number of information processing apparatuses being arranged in a first axis direction, each information processing apparatus including a plurality of the communication units,

wherein a number storage unit that stores, for respective information processing apparatuses, serial integer numbers allocated to respective information processing apparatuses sequentially from a predetermined position in the housing in the first axis direction, and after reaching an information processing apparatus at an end in the first axis direction, from another end in a level that is shifted by one in a second axis direction is further comprised as the position information, and

wherein the allocation unit allocates different channels to respective communication units based on the number storage unit.

4. The information processing apparatus according to claim 1,

wherein each information processing apparatus includes a plurality of the communication units,

wherein an identifier storage unit that stores, for each information processing apparatus, an apparatus identifier used to identify the information processing apparatus and a position in the housing is further comprised as the position information, and

wherein the allocation unit allocates different channels to respective communication units based on the identifier storage unit.

5. The information processing apparatus according to claim 1,

wherein each information processing apparatus includes a plurality of the communication units,

wherein a reversal information storage unit that stores a bit value reversed for adjacent information processing apparatuses in the housing is further comprised as the position information, and

wherein the allocation unit allocates different channels to respective communication units based on the reversal information storage unit.

6. The information processing apparatus according to claim 1,

wherein each information processing apparatus includes a plurality of the communication units, and

wherein the allocation unit allocates, in association, all channels included in a predetermined frequency band to communication units of the number of channels.

7. The information processing apparatus according to claim 1,

wherein each information processing apparatus includes a plurality of the communication units, and

wherein the allocation unit selects, from all channels included in a predetermined frequency band, channels of the number of communication units, and allocates the selected channels to respective communication units.

8. The information processing apparatus according to claim 2, comprising:

a use information storage unit, as the position information, that stores information about whether or not to use each communication unit, based on a position in the housing,

wherein the allocation unit allocates different channels to respective communication units based on the use information storage unit.

9. A communication method performed by an information processing apparatus in a housing, the method comprising:

allocating a channel to be used for wireless communication by the self apparatus based on position information of the self apparatus in the housing in such a way that the channel is not same as a channel to be used for wireless communication in a same direction by an adjacent information processing apparatus; and

performing wireless communication with another information processing apparatus in the housing by using the allocated channel.

10. A computer-readable storage medium storing a communication program that causes a processing device embedded in an information processing apparatus in a housing to execute a process comprising:

allocating a channel to be used for wireless communication by the information processing apparatus based on position information of the information processing apparatus in the housing in such a way that the channel is not same as a channel to be used for wireless communication in a same direction by an adjacent information processing apparatus; and

instructing that wireless communication is to be performed with another information processing apparatus in the housing by using the allocated channel.
