Abstract: A method and system for increasing throughput in a hierarchical wireless network is described. The hierarchical wireless network includes a plurality of nodes and each of the plurality of nodes has a primary path to the root node. First, one or more channels from a plurality of available channels are allocated to each disjoint sub-tree associated with the root node. Then, alternate one or more disjoint paths from at least one node in the plurality of nodes to the root node through alternate disjoint sub-trees associated with the root node are determined. Next, data from the at least one node is sent to the root node through a primary path and one or more alternate disjoint paths.

Abstract: The present disclosure provides methods and systems for automatic gain control (AGC) in a multiple input multiple output (MIMO) system having two or more receiver chains, each receiver chain including a receiver and an AGC module. The AGC system accepts a signal at a compensation module associated with the receiver chain and calculates one or more gains using the AGC module associated with the receiver chain. Then, an estimation module computes a scaling factor for each receive chain from the gains and transmits the scaling factor to the compensation module of the respective receiver chain, which requantizes the signal based on the scaling factor.

Abstract: A method for improving quality of real time data streaming over a network. The network includes a plurality of nodes. A source node in the plurality of nodes transmits a real time data packet to a destination node in the plurality of nodes. First, the source node obtains maximum latency information about the data packet of a data frame. The source node stores information about the maximum latency in the data packet. Then, the source node and zero or more intermediate nodes route the data packet from the source to the destination such that the data packet reaches the destination before the maximum latency expires. Each intermediate node, updates the maximum latency of a packet by subtracting the time spent by the packet at the intermediate node from the maximum latency value received along with the packet.

Abstract: The present invention provides a method and system for reducing power consumption in a Wireless Sensor Network. The Wireless Sensor Network includes a plurality of nodes forming a tree structure. The nodes send data towards a root node via parent nodes. The nodes adaptively control the wake-up schedules of radio transceivers based on the network level information of the nodes, thereby reducing the active wake-up interval of the radio transceivers and in turn decreasing the overall power consumption of the Wireless Sensor Network.
