Patent ID: 8576876

Claim:
A method for determining a throughput of a short range wireless network, comprising: acquiring respective time parameters in a contention access period based on information transmission characteristics of the short range wireless network, wherein the respective time parameters are determined based on a non-persistent Carrier Sense Multiple Access (CSMA) mechanism; and determining the throughput of the short range wireless network based on the respective time parameters in the contention access period; wherein determining the throughput of the short range wireless network comprises: determining a duration of an investigation cycle in the network based on the respective time parameters in the contention access period and average collision times in an investigation cycle, and determining the throughput of the short range wireless network based on a payload length and the duration of the investigation cycle; wherein the average collision times are determined based on: a probability of collision of a current transmission after a success of a last transmission, and a probability of collision of the current transmission or a success of the current transmission after a collision of the last transmission, and wherein the probability of collision of the current transmission and the success of the current transmission are both determined based on a conditional probability of a first clear channel assessment (CCA) given that a device is in a backoff state.
