Abstract
A first node receives aggregated compressed data and unaggregated data from a second node in a wireless multi-hop network. The first node compresses its own collected data based on the received unaggregated data. The first node aggregates its own compressed data with the aggregated compressed data received from the second node. The first node forwards an unaggregated version of its own collected data along with aggregated compressed data to a next hop in the wireless multi-hop network.
Claims11
A method for compressing data, comprising:
- receiving aggregated compressed data and unaggregated data at a first node from a second node in a wireless multi-hop network;
- compressing data collected by the first node based on the unaggregated data;
- aggregating compressed data collected by the first node with aggregated compressed data received from the second node;
- and
- forwarding an unaggregated version of the data collected by the first node and aggregated compressed data to a next hop in the wireless multi-hop network.
A wireless sensor node, comprising:
- a receiver to receive aggregated compressed data and unaggregated data from a neighbor node in a wireless multi-hop network;
- a data compressor to compress data collected by the sensor node based on the unaggregated data received from the neighbor node;
- an aggregation module to aggregate compressed data collected by the sensor node with aggregated compressed data received from the neighbor node;
- and
- a transmitter to forward an unaggregated version of sensor data collected by the sensor node along with aggregated compressed data to a next hop in the wireless multi-hop network.
