Abstract

A single host device, comprising a plurality of communication devices, estimates bandwidth requirements such as maximum rates and/or an average data rate expected by each of a plurality of applications to be run on the single host. For each communication device, available frequencies utilized are determined based on the estimated bandwidth requirements. Each of the plurality of applications is allocated to corresponding one or more communication devices based on the determined available frequencies so as to, for example, concurrently run corresponding applications on the single host. The determined available frequencies are assigned to corresponding communication devices based on the estimated bandwidth requirements. The determined available frequencies and the plurality of applications may be reassigned and reallocated, respectively. Each of plurality of applications is allocated to the corresponding one or more communication devices based on the assigned/reassigned available frequencies and/or the estimated bandwidth requirements.

Claims

performing, by a single host device, load balancing of a plurality of applications among a plurality of communication devices, the single host device coupled to the plurality of communication devices;

determining available bandwidth corresponding to each communication device among the plurality of communication devices; and

allocating the plurality of applications to at least a portion of the plurality of communication devices based on at least one of;

the load balancing of the plurality of applications or the determined available bandwidth.

2. The method of claim 1, wherein the single host device is coupled to the plurality of communication devices via a plurality of Bluetooth connections.

3. The method of claim 1, wherein at least a portion of the plurality of applications are executed by the single host device to facilitate a plurality of Bluetooth communications by at least the portion of the plurality of communication devices.

4. A system comprising:

a single host device coupled to a plurality of communication devices;

wherein the single host device is configured to estimate a bandwidth requirement for each application among a plurality of applications to be executed by the single host device;

wherein the single host device is further configured to determine a plurality of available frequencies to be utilized by each communication device among the plurality of communication devices based on the estimated bandwidth requirement; and

wherein the single host device is further configured to assign the determined a plurality of available frequencies to the plurality of communication devices based on the estimated bandwidth requirements, wherein assignment of the determined available frequencies is further based on whether the determined available frequencies are even frequencies or odd frequencies.

5. The system of claim 4, wherein the single host device is further configured to concurrently execute at least a portion of the plurality of applications.

6. The system of claim 4, wherein the estimated bandwidth requirement comprises comprise at least one of:
