Abstract

A system and method of determining a data collection routing protocol include the steps of perceiving a broadcast beacon message from an i-th sensor node located at an i-th sensor level by one or more sensor nodes at one or more other sensor levels of a divided WSN, wherein the i-th sensor level does not include a first sensor level of a sink sensor node; resetting the respective sensor level of the one or more sensor nodes to an (i+1)th sensor level; attempting to connect the i-th sensor node at the i-th sensor level to another sensor node located at an (i−1)th sensor level; and connecting the i-th sensor node to a parent sensor node at the i-th sensor level when certain conditions are met. These conditions are determined and analyzed locally at each sensor node.

Dependent claims

A method of determining a data collection routing protocol, the method comprising:

sensing one or more beacon messages at a source sensor node from neighboring sensor nodes within a wireless sensor network (WSN);
measuring, via the source sensor node a Received Signal Strength Indicator (RSSI) of the beacon messages from the neighboring sensor nodes;
inputting the measured RSSI and data for an available energy, a harvested energy, a packet transmission energy, an energy harvesting rate, and a packet reception energy of the neighboring sensor nodes into a routing table stored in memory at the source sensor node;
calculating a weighted RSSI for all entries of the routing table for child sensor nodes located at a lower sensor level from a source sensor node level;
connecting the source sensor node to one of the child sensor nodes based upon the weighted RSSI and the data of the associated child sensor node;
and
connecting the source sensor node to a parent sensor node located within the source sensor node level when connecting the source sensor node to one of the child sensor nodes is not completed before a predetermined timeout,
wherein the sensor nodes are interconnected to a gateway sensor node which is wirelessly connected to a server.
