Systems and methods for improving data transmission rates in communication networks are disclosed. In an 802.11 wireless communication network, where a source node of the wireless network transmits TCP data to a destination node of the wireless network, the destination node does not transmit TCP acknowledgments (ACKs) for the TCP data if 802.11 ACKs indicate that the destination node received the TCP data. If a source outside the wireless network transmits TCP data to the destination node within the wireless network through an intermediate device, such as an access point, the destination node suppresses transmitting TCP ACKs. The intermediate device transmits TCP ACKs as proxy for the destination node to the source. The intermediate device also suppresses TCP ACKs where a source node within the wireless network sends the TCP data to a destination node outside of the wireless network.

An observation system includes a first sensor configured to observe a first portion of an observation target, a second sensor configured to observe a second portion of the observation target, and a control device including a memory and a processor coupled to the memory, the processor being configured to receive first observation data from the first sensor via a first relay device and second observation data from the second sensor via a second relay device, wherein the first observation data is not transmitted from the first sensor to the second relay device when the first observation data is transmitted from the first sensor to the control device via the first relay device, and the second observation data is not transmitted from the second sensor to first relay device when the second observation data is transmitted from the second sensor to the control device via the second relay device.

A wireless relay exchanges user data with User Equipment (UE) over a wireless user link. The wireless relay exchanges a first portion of the user data with an internet over a wireless communication network. The wireless relay exchanges a second portion of the user data with the internet over a Local Internet Protocol Access (LIPA) network. The wireless relay tracks the exchanged user data by media type and network type. The wireless relay transfers network usage data to a network server. The network usage data indicates first amounts of the user data by the media type that were exchanged with the internet over the wireless communication network. The network usage data indicates second amounts of the user data by the media type that were exchanged with the internet over the LIPA network.

Various embodiments disclosed herein provide for an enhanced timing advance scheme to support MU-MIMO in an integrated access and backhaul system. The timing advance scheme disclosed herein aligns the arrival time between backhaul links and access links to enable MU-MIMO gain at the receiver side. In the integrated access and backhaul system, which comprises distributed nodes, the timing advance offset for an access link transmission (a transmission to a node further away in hops from the core network, or to a user equipment device) can be modified by offsetting it with the timing advance of the backhaul link (e.g., from a parent node). This enables the arrival time for transmissions, both access link transmissions from the UE or child node, and backhaul link transmissions from a parent node to arrive at the same time.

Disclosed herein are a method for performing, by a first node, a relay function in a Bluetooth mesh network and an apparatus performing the method. The method includes transmitting a first message for activating or deactivating the relay function of the first node to a plurality of neighboring nodes when a specific event is generated and activating or deactivating the relay function depending on whether a first indication message to request the activation of the relay function is received or not in a response to the first message within a first specific time from at least one of the plurality of neighboring nodes. The specific event is one of receiving a command indicating the setting of the relay function, a specific cycle, or receiving a second message for activating or deactivating the relay function from the neighboring nodes.

A network relaying device facilitates communication among a plurality of network nodes. When the network relaying device receives a data packet from a first network node, it determines whether a historical transmission rate of the first network node exceeds a threshold rate. Based on this determination, the network relaying device determines whether to associate the data packet with a first queue or a second queue for transmission to a second network node.
