H04W 4/00
H04J 3/12

US Classification:

370230, 370337, 370338, 370347

Abstract:

A method to schedule network communications includes determining nodes within a network, forming a node list based on the nodes in the network, determining a network schedule of communications for the nodes based on the node list. Determining a network schedule includes determining a timeslot. Each node receives data during the timeslot.

International Classification:

G01R 31/08

US Classification:

370230, 370254, 370336

Abstract:

In one aspect, a method to schedule network communications includes transmitting a node identification associated with a first node joining a network over a first portion of control timeslots based on a first probability, detecting nodes in the network using a second portion of the control timeslots and receiving acknowledgments from at least one of the nodes in the network. The method also includes that if a ratio of a number of acknowledgments received to a number of the nodes in the network detected is greater than a predetermined percentage: transmitting control data over the first portion of the control timeslots based on a second probability associated with a number of the nodes detected and transmitting data over the second portion of the control timeslots based on a network schedule.

Appl. No.:

12/508747

Inventors:

Sung I. Park - Irvine CA, US
Darryn A. Johnnie - Brea CA, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

H04L 12/28

US Classification:

3703954, 370408

Abstract:

In one aspect, a method to multicast in a network includes determining using a processor a least amount of relay nodes for use in multicasting a message to nodes in the network by using a neighbor matrix of a source node used in Node Activation Multiple Access (NAMA) scheduling. The method may include designating a one-hop neighbor that exclusively accesses the two-hop neighbor of the source node as a relay node. The method may also include designating a one-hop neighbor of the source node with accessibility to a maximum number of two-hop neighbors of the source node as a relay node.

Appl. No.:

12/356778

Inventors:

Denh T. Sy - Rosemead CA, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

H04J 3/00

US Classification:

370345, 370350, 370322, 370324, 370238

Abstract:

In one aspect, a method includes scheduling network communications in a network comprising nodes connected by links, receiving at a first node updated bandwidth values from the other nodes, determining a cluster coefficient based on a number of one-hop neighbors of the first node and a number of neighbors N-hops and less of the first node, adjusting the cluster coefficient to form an adjusted cluster coefficient and determining a wait period based on the adjusted cluster coefficient. The method also includes implementing the updated bandwidth values received to determine updated node weight values of the other nodes after the wait period has expired.

Inventors:

Sung Guk Park - Seattle WA, US

Assignee:

Sung Guk Park - Seattle WA

International Classification:

G06F 17/30

US Classification:

707822, 711100

Abstract:

A method of operating multiple files includes creating a group of computer files using a single container, and opening multiple files of the group and associated application software by opening a single file corresponding to the group of computer files.

G06F 15/173

US Classification:

370225, 455445, 709239

Abstract:

Methods for determining paths that satisfy a reliability requirement are generally described herein. The methods may include receiving path information. A reliability requirement is established, and paths that satisfy the reliability requirement are determined. Each path comprises nodes. Configuration of the nodes of the paths according to the reliability requirement is facilitated. A code rate may be determined that corresponds to the reliability requirement. The code rate may indicate network coding to be performed by least a subset of the nodes. The method may also include sending the code rate to the nodes of the paths.

International Classification:

H04L 12/56

US Classification:

370400

Abstract:

In one aspect, a method includes receiving a packet at a first node, the first node comprising a processor, determining, at the first node, whether a destination node of the packet is within a zone of the first node, using, at the first node, an on-demand routing protocol to route data from the first node to the destination node if the destination node is outside the zone of the first node and using a network topology, stored at the first node, to route the packet from the first node to the destination node if the destination node is within the zone of the first node.

International Classification:

H03M 13/05

US Classification:

714776, 714E11032

Abstract:

In one aspect, a sub-packet error correction method includes receiving a data packet, segregating the data packet into sub-packets, and encoding the sub-packets using an erasure code for transmission over a network, and receiving the encoded sub-packets, decoding the sub-packets, and combining the decoded sub-packets to reconstruct the data packet. In some embodiments, the data packet is received at a first proxy server for transmission over a lossy network, the encoded sub-packets received at a second proxy server over the lossy network.
