A system comprising: a container with a beacon, the beacon adapted to broadcast a signal inside the container; one or more items placed inside the container, the one or more items comprising: a location detection module adapted to determine a location based on the signal received from the beacon; a battery level determination module adapted to determine a charged status of a battery associated with each of the one or more items; a first transmitter adapted to transmit the location and the charged status of the battery associated with each of the one or more items to a server; and a first receiver adapted to receive a message from the server; and the server comprising: - a second receiver adapted to receive the location and the charged status of the battery associated with each of the one or more items from the first transmitter of the one or more items; - a clustering unit adapted to assign a cluster to a group of items from the one or more items based on the location of each of the one or more items; - a processor adapted to identify a master item from the group of items in the cluster based on the charged status of each item in the cluster; - a second transmitter adapted to transmit a message to the master item for sensing a parameter inside the container for the group of items in the cluster; and - the second receiver further adapted to receive a sensed parameter for the group of items in the cluster from the master item in response to the message characterized in that the signal from the beacon is utilized to determine: a first factor (h) related to a height of each of the one or more items from bottom of the container; a second factor related to a distance between each of the one or more items and a top wall of the container; and a third factor related to a distance between each of the one or more items and the beacon in the container. a container with a beacon, the beacon adapted to broadcast a signal inside the container;
