Algorithm for assigning the HopIDs with the help of hello packets Two types of Hello packets (hp) broadcasts sink hello packet(S-hp) and courier hello packet(C-hp) From each Sink (S-hp) with HopID "[N.sub.10.00.00.00]"or "[N.sub.01.00.00.00]" Max Hop Count = 8 for BSN Max Hop Count = 4 for DRN Max Hop Count = 4 for DDN From Courier node (C-hp) with HopID "[N.sub.11.00.00.00]" & Max Hop Count = 8 for BSN Max Hop Count = 4 for DRN Max Hop Count = 4 for DDN Default nodes addresses: Right SINK -- 01.00.00.00 Left SINK -- 10.00.00.00 Courier Node -- 11.00.00.00 (if more than 1, then DDN node -- 11.44.44.88 increase like 12, 13...
A similar pattern is followed by DRN and BSN nodes for updating of their hop addresses.
In this regard, N66 wins the competition due to the higher level node (DRN).
In this situation, N69 is upper-level DRN node with smaller C-HopID considered as the next hop.
BSN node generates a data packet; that is collected by DRN nodes and forwards it to the nearest DDN node.
Keeping in view the lengths of the pipeline, we used 1000M pipeline and distributed its length into BSN, DRN, DDN and CN types of nodes.
Due to simulator limitations, we have deployed 4 BSNs per one DRN that help to monitor more area with minimum cost in the network.
From these results, it is evident that only 1-2% courier nodes improve data delivery ratios up to 85-95% with the presence of the ordinary nodes like BSN, DRN and DDN.
