Abstract
The present invention relates to the field of contention in a network of communicating nodes. The present invention especially relates to a master node for a communication network, to a slave node device for a communication network, to a network comprising the master node device and at least one slave node device and to a method of contention in a network of nodes. The method of contention according to the present invention is method in a network comprising slave nodes, said slave nodes comprising a group of first slave nodes, the method comprising the step of sending, by every first slave node participating in a contention, a number of two or more contention participation messages during a contention window associated with the first slave node.
Claims25
A master node device (1) for a communication network (3) comprising slave nodes (2), said slave nodes comprising a group of first slave nodes (2), said master node device (1) comprising
- a communication unit (4-1) operable to
- receive two or more contention participation messages (9) sent from one first slave node (2) during a contention window (12) associated with that first slave node (2),
- select one of the received two or more contention participation messages (9) for further processing and neglect the others.
A slave node device (2) for a communication network (3) comprising slave nodes (2), said slave nodes (2) comprising a group of first slave nodes (2), said slave node device (2) being a member of said group of first slave nodes (2),
- said slave node device (2) comprising
- a communication unit (4-2) adapted to send two or more contention participation messages (9) during a contention window (12) associated with the slave node device (2).
A method of contention in a network (3) comprising slave nodes (2), said slave nodes (2) comprising a group of first slave nodes (2), the method comprising the step of
- sending (S18), by every first slave node (2) participating in a contention, a number of two or more contention participation messages (9) during a contention window (12) associated with the first slave node (2).
