THE 3-HOP AHEAD PATH RESERVATION METHOD IN WIRELESS SENSOR NETWORKS

摘要

PURPOSE: A 3-hop ahead path reservation method in a wireless sensor network is provided to ensure, in advance, transmission for the traffic having higher priority through a path reservation technique. CONSTITUTION: A wireless sensor network enlarges the space between nodes as 3-hole in order to enable reservation and transmission at the same time. The wireless sensor network performs the reservation and data transmission at the same time for two nodes that are distanced over 3-hops. The wireless sensor network is configured with the data transmission after completing the reservation up to a sync node(31).
