Abstract
The present invention is directed to providing a wireless medium access control protocol wherein throughput can be optimized as the communication system dynamically changes when nodes either join or leave the communication system.
Claims5
Apparatus for controlling wireless communication among plural nodes in a frequency hopping communication system comprising:
- means for monitoring a number of transmissions which occur within the communication system, said means for monitoring including maintaining a linked list of nodes which have transmitted information within a predetermined period of time;
- and
- means for dynamically changing a number of slots for which nodes of the communication system contend for access to a wireless communication medium of the communication system, said dynamic changing being performed as a function of said number of monitored transmissions,
- wherein said linked list includes timestamp information regarding a time at which each of said nodes transmitted information, said linked list being sorted according to said timestamps.
