1. A wireless communication network comprising:
- a plurality of mobile nodes each comprising a wireless transceiver and a controller for controlling said wireless transceiver, said controller also forscheduling a plurality of time slots for establishing a communication link with a neighboring mobile node for transmitting data therebetween, the data having a plurality of priority levels, each priority level having a minimum quality threshold associated therewith,determining respective link quality values associated with the communication link during each time slot, andprioritizing data to be transmitted during the time slots based upon the priority level of the data and the link quality values including prioritizing the data to be transmitted by assigning data corresponding to a given priority level to a first available time slot for which the link quality value is above the respective minimum quality threshold.

Abstract
A wireless communication network may include a plurality of mobile nodes each including a wireless transceiver and a controller for controlling the wireless transceiver. The controller may also be for scheduling a plurality of time slots for establishing a communication link with a neighboring mobile node for transmitting data therebetween, where the data has a plurality of priority levels. The controller may also determine respective link quality values associated with the communication link during the time slots, and prioritize data to be transmitted during the time slots based upon the priority level of the data and the link quality values.

8. A wireless communication network comprising:
-
a plurality of mobile nodes including a source node and a destination node for establishing a communication link therebetween during a time slot; said source node transmitting a predetermined number of data packets to said destination node during the time slot along with an overhead packet indicating the number of data packets transmitted; said destination node determining a packet reception error value associated with the time slot based upon a number of data packets received and the number of data packets transmitted if the overhead packet is received, and otherwise estimating the packet reception error value based upon a fraction of the time slot occupied by received data packets. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A communication method for a wireless communication network comprising a plurality of mobile nodes, the method comprising:
-
scheduling a plurality of time slots for establishing a communication link between a pair of mobile nodes for transmitting data therebetween, the data having a plurality of priority levels, each priority level having a minimum quality threshold associated therewith; determining respective link quality values associated with the communication link during each time slot; and prioritizing data to be transmitted during the time slots based upon the priority level of the data and the link quality values including prioritizing the data to be transmitted by assigning data corresponding to a given priority level to a first available time slot for which the link quality value is above the respective minimum quality threshold. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A method for communicating between a source node and a destination node in a wireless communication network comprising a plurality of mobile nodes, the method comprising:
-
establishing a communication link between the source node and destination node during a time slot; transmitting a predetermined number of data packets from the source node to the destination node during the time slot along with an overhead packet indicating the number of data packets transmitted; and determining a packet reception error value associated with the time slot based upon a number of data packets received by the destination node and the number of data packets transmitted by the source node if the overhead packet is received by the destination node, and otherwise estimating the packet reception error value based upon a fraction of the time slot occupied by received data packets. - View Dependent Claims (25, 26, 27, 28, 29, 30)
