A system for allocating tasks within a moving multi-hop mesh network includes a processor operatively coupled to memory. The processor is configured to implement the steps of: sending a bid request from a first network node to two or more other network nodes for computing a task, wherein the first network node has a first geographical location relative to a first geographical location of the two or more other network nodes; in response to the first network node receiving a bid from at least two of the two or more other network nodes for computing the task; predicting a second geographical location for each of the at least two of the two or more other network nodes relative to a second geographical location of the first network node based on the time when the task will be completed; predicting a total task completion time for the at least two of the two or more other network nodes; comparing the total task completion time predicted for the at least two of the two or more other network nodes to generate a winning bid; and allocating the task to the winning bid.

Dynamic task allocation and node reconfiguration in mesh network

A computer-implemented method for implementing an overlay network on peer-to-peer network to enable resource allocation that accounts for attributes and statuses of one or more nodes therein is provided. The computer-implemented method includes registering one or more nodes with the overlay network and executing overlay registration routing of the one or more nodes by building a routing table to cause node types to know about each other. Overlay sorting is executed between the node types based on corresponding characteristics.

Peer-to-peer network for internet of things resource allocation operation

A system, method and program product for managing a moving peer-to-peer network. A system is provided that a node tracking system that collects tracking information of nodes in a moving P2P network including position, connection status and computation capability; a network representation system that stores the tracking information in a dynamic graph that specifies nodes and connections between the nodes; a task manager for receiving a task submitted by a requesting node for a service implemented by a provider node; and a network allocation system that determines and allocates an optimal path back and forth between the requesting node and the provider node, wherein the optimal path is selected to minimize an overall wall-time, and wherein the network allocation system estimates future positions of moving nodes for determining the optimal path.

Techniques for power sharing in DC networks using virtual impedance frequency droop control are provided. In one aspect, a method for power sharing in a DC network having multiple electrical energy generation sources connected to at least one load includes the steps of, at each of the electrical energy generation sources: generating a controllable DC voltage; superimposing a controllable AC signal on top of the DC voltage; regulating the AC signal using virtual impedance frequency droop control; and determining a desired DC voltage output using the regulated AC signal. The DC voltage can then be regulated to match the desired DC voltage output. A system for power sharing in a DC network is also provided.
