Coordinate-based addressing for MANET

“…In one MANET, neighbors can directly communicate with each other whereas nodes beyond each other's communication range must depend on intermediate nodes to perform indirect communications [2]. During a communication process, a node uses a unique address to identify itself, so a requisite of performing correct communications is that each node is configured with a unique address [3,4]. In order to achieve address configuration for one MANET, some addressing approaches [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] are proposed.…”

“…Coordinates= (1,5,3,4) Node ID=1 New node ID=0 At T1: New node ID space= [1,0xF] At T2: New node ID space= [1,7] X At T2 MANET ID=0xA3EF Coordinates= (1,5,3,4) Node ID=1 New node ID=8 New node ID space= [9,…”

“…In this way, Z 1 /Z 2 /Z 3 acquires unique node ID 0/1/2 via the node ID initialization sub-process. Then, Z 1 /Z 2 /Z 3 constructs a unique address where the MANET ID is 0xA3EF, the 4-tuple coordinates are (1,5,3,4), the node ID is 0/1/2 and the new node ID is zero.…”

“…5a, at time T1, X requests an address from X2. At time T2, X acquires an address where the MANET ID is 0xA3EF, the coordinates are (1,5,3,4), the node ID is 1 and the new node ID is 8.…”
