In a wireless network, a wireless device may dynamically estimate how long it can remain in a sleep mode without missing out on necessary opportunities to communicate within the network. In some embodiments, this estimate may be based at least partly on an estimate of how long it will take to transmit data in a transmit queue.

Scheduling for power savings in a wireless network

Embodiments of a wireless communication device and method for dynamic bidirectional aggregation of media-access control (MAC) layer frames in a wireless network are generally described herein. Other embodiments may be described and claimed. In some embodiments, the time between consecutive bursts is dynamically varied based on a MAC channel access delay.

A multicarrier receiver changes receive capabilities based on a current channel utilization. The number of antennas used to receive multicarrier communication signals may be changed or the channel bandwidth may be changed.

Multi-antenna multicarrier receiver and methods for adaptively adjusting a receive data rate based on channel utilization

Embodiments of systems and methods for Bluetooth and WiMAX coexistence are generally described herein. Other embodiments may be described and claimed. In some embodiments systems and methods are described to determine a temporal reference associated a frame, and then align another wireless frame with that temporal reference. Once aligned, transmissions and receptions in one wireless frame may be arranged to not temporally overlap with transmissions or reception the other wireless frame.

Systems and methods for scheduling transmissions for coexistence of differing wireless radio protocols

In general, in one aspect, the disclosure describes a method that includes selecting an offset between start of communications of a first radio in a multi-radio platform (MRP) and start of communications of a second radio in the MRP. Synchronizing clocks of the first radio and the second radio to maintain the offset. Determining safe zones within the communications of the second radio based on configuration of the first radio and the second radio and the selected offset. The safe zones are locations that minimize conflicts between receiving operations of the first radio that are at fixed locations and transmitting operations of the second radio and transmitting operations of the first radio that are at fixed locations and receiving operations of the second radio.

Minimizing mutual interference for multi-radio co-existence platforms

Systems and methods provide for controlling contention in a wireless network device. The systems and methods transmit a packet on a wireless network. If the transmission is not successful, then a contention window parameter is adjusted according to a fast backoff operation. If the packet transmission was successful and the current value of the contention window parameter is less than a threshold value then the contention window parameter is decreased according to a contention avoidance operation. If the packet transmission is successful and the current value of the contention window parameter is greater than the threshold value then the contention window parameter is decreased according to a slow start operation.

Systems and methods for contention control in wireless networks

Systems and methods provide a secure network path through an inner and outer firewall pair between a mobile node on a foreign network and a corresponding node on a home network. One aspect of the systems and methods includes providing a mobile IP proxy between the mobile node and a VPN gateway inside the firewalls. The mobile IP proxy acts as a surrogate home agent to the mobile node, and acts as a surrogate mobile node to a home agent residing on the home network.

Service discovery architecture and method for wireless networks

The present disclosure relates to determining and establishing at least two node disjoint paths, and, more specifically, to determining and establishing at least two node disjoint paths within a wireless ad-hoc network that includes a source and a target node using on-demand flooding.

Determining two node-disjoint paths using on-demand flooding

Network devices on mobile networks may be configured to improve and optimize packet processing and routing. Specifically, a home agent device may be decomposed into its major functionality, namely processing and routing. Various processors on the device are assigned to specific tasks and each processor may be optimized for its specific tasks, thus improving packet processing and routing. The home agent device may comprise one or more physical components.

Method, apparatus and system for optimizing routing of mobile IP packets

A method for correctly routing packets is described. The method includes receiving an encapsulated packet from a sending mobile node destined for a receiving mobile node. The method determines whether the encapsulated packet is from a mobile node with the recipient as its home agent (reverse tunneled packet), whether the inner packet is destined to a mobile node with the recipient as its foreign agent, and whether the packet had been received in a previous reception. If the answers for all the three are yes, the packet is then delivered to the receiving mobile node. If the answers are yes only for the first two questions, the packet is routed and transmitted away normally and a copy of the packet IP header is cached locally. For all other cases, the packet is routed and transmitted away normally.

Performance for integrated home agent and foreign agent

Maintaining a reliable link includes altering a record of information transmitted across a network from a mobile unit to a destination based on an acknowledgment by the destination of receipt of the transmitted information and transmitting information from the mobile unit to the destination based on the record after the mobile unit establishes a new interface connection to the destination.

Maintaining a reliable link

A network includes a TCP-in-TCP tunnel between a mobile device, which includes a TCP client and a gateway, and a TCP server, which resides in a subnet. Another gateway in the subnet receives and caches TCP packets and acknowledgments (ACKs) from the TCP-in-TCP tunnel. In response to receiving an indication from the TCP server that it has not received a cached TCP packet, the second gateway may resend the packet without relaying the indication to the TCP client, and the first gateway may send a control message instead of a complete TCP packet to the second gateway.

System and method for reducing retransmissions due to tunneled TCP-in-TCP communication in a network

The present invention supports mobility for a mobile node between different packet data services. In one embodiment, the invention includes listening for a registration message from a mobile node at an external interface of a gateway node of a wireless packet service, the registration message containing a care-of address for the mobile node that is outside of the wireless packet service, accepting a registration message from the mobile node at the external interface, and registering the mobile node to the care-of address contained in the registration message. This embodiment further includes sending a registration reply message to the mobile node via the care-of address, the registration reply message indicating successful registration, creating a binding for the mobile node, tunneling packets addressed to the mobile node to the care-of address, and receiving tunneled packets from the mobile node, decapsulating the tunneled packets and sending them to the appropriate address.
