Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
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.
Claim 2
Dependent Claim
118 words
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.
Claim 3
Dependent Claim
23 words
Apparatus according to claim 1, wherein said monitoring means detects a number of data packet transmissions sent within a predetermined period of time.
Claim 4
Dependent Claim
22 words
Apparatus according to claim 1, wherein said monitoring means detects a number of request-to-send messages sent within a predetermined period of time.
Claim 5
Dependent Claim
43 words
Apparatus according to claim 1, wherein said means for dynamically changing is performed as a function of said number of monitored transmissions received in a predetermined period of time, said predetermined period of time being variable based on activity of the communication system.
Claim 6
Dependent Claim
112 words
Method for controlling wireless communication among plural nodes in a communication system, comprising the steps of: monitoring a number of transmissions which occur within the communication system by maintaining a linked list of nodes which have transmitted information within a predetermined period of time; and 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 step of dynamically changing being performed as a function of said number of monitored transmissions, said linked list including timestamp information regarding a time at which each of said nodes transmitted information, said linked list being sorted according to said timestamps.
Claim 7
Dependent Claim
112 words
Method for controlling wireless communication among plural nodes in a communication system, comprising the steps of: monitoring a number of transmissions which occur within the communication system by maintaining a linked list of nodes which have transmitted information within a predetermined period of time; and 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 step of dynamically changing being performed as a function of said number of monitored transmissions, said linked list including timestamp information regarding a time at which each of said nodes transmitted information, said linked list being sorted according to said timestamps.
