1. A system for processing a computational task, comprising: a plurality of nodes operationally coupled to one another via one or more networks, the plurality of nodes, comprising: a base node comprising a processing subsystem configured to: receive the computational task; determine nodes that are available from the plurality of nodes based on receipt of response to a query signal broadcasted to the plurality of nodes via at least one of one or more communication modes available in the one or more networks; select a subset of available nodes from nodes available in the plurality of nodes based on information present in the response to the query signal, wherein the information comprises a present status, processing capability, distance from the base node, network throughput, range, resources, features, or combinations thereof; divide the computational task into a plurality of sub-tasks; distribute one or more of the plurality of sub-tasks for processing among the subset of available nodes using one of the one or more communication modes based on cost of using each of the one or more communication modes, and at least one of a number of nodes in the subset of available nodes, completion time period allowed for each of the plurality of sub-tasks, a distribution criteria, level of security required for the completion of the plurality of sub-tasks by the computational task, resources available with each of the subset of available nodes, processing capability of each of the subset of available nodes, reliability of the subset of available nodes, trust of the base node in the subset of available nodes, the current load on the subset of available nodes, or combinations thereof; receive sub-solutions corresponding to the plurality of sub-tasks generated at the subset of available nodes within a desired time period; verify receipt of the received sub-solutions within the desired time period to determine existence of one or more unprocessed sub-tasks from the plurality of sub-tasks; redistribute the one or more unprocessed sub-tasks, to generate sub-solutions, to new nodes from the nodes that are available in the plurality of nodes; receive sub-solutions corresponding to the one or more unprocessed sub-tasks within the desired time period; and reassemble the sub-solutions to determine a solution corresponding to the computational task.
