Receiver scheduling in ad hoc wireless networks
First Claim
Patent Images
1. A wireless network, comprising:
- a node configured to periodically generate and transmit at least one reception definition, each of the at least one reception definition indicating a time and manner in which the node will operate to receive information messages, the time including a time at which the node will power up a receiver to receive the information messages where, when generating the at least one reception definition, the node is configured to derive parameters delineating each of the at least one reception definition via pseudo-random number generation or physical random number generation.

Abstract
A wireless network (100) includes a communications node (120) configured to periodically generate and transmit at least one reception definition. Each reception definition indicates a time and manner in which the node will operate to receive information messages.

13. A node for use in a wireless network, comprising:
-
a memory configured to store instructions, and a processor configured to execute the instructions to; generate a local receiver schedule including a number of reception definitions, each reception definition indicating a time and manner in which the node will operate to receive information messages, the time including a time at which the node will power up a receiver to receive the information messages, periodically modify the local receiver schedule, and cause a prevailing local receiver schedule to be transmitted together with information messages bound for other nodes in the wireless network. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method of performing receiver scheduling at a node in a wireless network, the wireless network including a plurality of nodes, the method comprising:
-
generating a local receiver schedule at the node, the local receiver schedule including a number of reception definitions, each reception definition indicating a time and manner in which the node will operate to receive information messages from other nodes in the network, the time including a time at which the node will power up a receiver to receive the information messages; periodically updating the local receiver schedule at the node; and periodically transmitting a most recently updated local receiver schedule from the node to other nodes in the network. - View Dependent Claims (25, 26, 27)

28. A computer readable medium encoded with instructions for controlling at least one node to perform a method, comprising:
-
generating a local receiver schedule, the local receiver schedule including a number of reception definitions, each reception definition indicating a time and manner in which the node will operate to receive information messages, the time including a time at which the node will power up a receiver to receive the information messages; periodically updating the local receiver schedule; and causing a most recently updated local receiver schedule to be transmitted together with information messages bound for other network nodes. - View Dependent Claims (29)
