1. A computer implemented system, comprising:
- a topology control component configured to distribute sensors as nodes among a dynamic wireless network in a form of a tree structure;
a data retrieval component configured to retrieve data from the sensors, the topology control component and the data retrieval component being part of a communication protocol employed by a base station to communicate with the sensors; and
a storage medium associated with at least one of the sensors for local storage of the data during a transition time for change of the dynamic wireless network.

Abstract
Systems and methods that provide for collection of sensor data in a wireless network with a dynamically changing structure. A data collection protocol exploits the self-awareness capabilities of nodes in selection of tree structures that form the wireless network during communication with a base station. The data collection protocol can further include a topology control component (which regulates how nodes are distributed among various tree structures and associated communication channels with the base station) and data retrieval component (which coordinates among the sensors to transmit data packets containing sensor data to efficiently employ available bandwidth).
