Classification: CPC H  Y | IPC H

Claim 0:
1. A wireless sensor network comprising:
one or more base stations;
a plurality of branch nodes communicatively coupled to each of the one or more base stations; and
a plurality of leaf nodes communicatively coupled to each of the branch nodes, wherein the plurality of leaf nodes are battery-operated, and wherein the one or more base stations, the plurality of branch nodes and the plurality of leaf nodes are configured for optimising energy consumption associated with each of the following:
transmitting sensor data from the leaf node to the branch node with a predefined periodicity only when a difference between a present sensor data and an immediate previous transmitted sensor data is greater than a predefined value, wherein the sensor data is at least a value measured by one or more sensors of the leaf node;
encrypting data transmitted between the leaf node and the branch node;
updating firmware of the branch node or of the leaf node, through over-the-air updates from a remote server;
sending data packets through the wireless sensor network based on a plurality of predefined levels of a Quality-of-Service; and
configuring radio duty cycle protocols at the base station or the branch node or both during transmission and reception of data packets from the leaf nodes.
