Energy Efficient Management of Heterogeneous Multi-Hop Wireless Networks

摘要

A wireless multi-hope network of nodes including data nodes and at least one sink node. The data nodes include battery-powered nodes (BPNs) having active and sleep periods and mains-powered nodes (MPNs) having only active periods, wherein each data node transmits the packets only within corresponding active periods. A BPN includes a transceiver for transmitting and receiving data packets and a processor for determining a schedule of active and sleep periods of the BPN independently from the active and sleep periods of other data nodes in the network and independently from commands transmitted by the sink node, and a battery for providing energy to the transceiver and the processor. The processor switches the transceiver ON and OFF according to the schedule.

1. A network of nodes including data nodes and at least one sink node, wherein the network is a wireless multi-hope network in which packets are exchanged between the sink node and the data nodes in a multi-hop manner such that there is at least one data node exchanging the packets with the sink node through at least one intermediate data node relaying the packets between the data node and the sink node, the data nodes include battery-powered nodes (BPNs) having active and sleep periods and mains-powered nodes (MPNs) having only active periods, wherein each data node transmits the packets only within corresponding active periods, a BPN comprising:
a transceiver for transmitting and receiving data packets; a processor for determining a schedule of active and sleep periods of the BPN independently from the active and sleep periods of other data nodes in the network and independently from commands transmitted by the sink node, wherein the processor switches the transceiver ON and OFF according to the schedule; and a battery for providing energy to the transceiver and the processor.
