A method and system for transmitting data based on deterministic quality of service by at least one peripheral device in a communication network is disclosed. The method includes exchanging reservation information with peripheral devices in the communication network, negotiating traffic specification (TSPEC) with the at least one peripheral device for at least one traffic type, based on the reservation information, establishing a quality of service associated with the at least one traffic type, using the TSPEC, reserving a wireless medium based on the established quality of service associated with the at least one traffic type and transmitting data through the reserved wireless medium, based on the quality of service and reservation information.
