Abstract:
PURPOSE: A multi-hop resource reservation method on the wireless sensor network is provided to minimize overhead in a multi-hop reservation process by giving payload of a control packet for efficient multi-hop resource reservation. CONSTITUTION: A source node transmits an MSRQ(Multi-hop Slot Reservation reQuest) message about a relay node(S700). A destination node receives a relayed MSRQ message through the relay node(S710). The MSRQ message includes a plurality of slot information. The destination node generates an MSRP(Multi-hop Slot Reservation rePly) message(S720). The destination node transmits the MSRP message to the source node through the relay node.
