Figure 3. Establishment of connection between nodes and sink: (a)the Sink sends an ADV packet to its neighbors and each node sends an RREQ to its own neighbors; (b)the sink replies to its neighbors with RREP; (c)the distant nodes send an RREQ to its neighbors; (d)the neighbors connected to the sink reply with a PREP and the node becomes connected to the sink
