If 7.2.1. in the forwarding queue of WSID node and WSID label bunch head or sent in buffer memory and have this packet, WSID node and WSID label bunch head do not forward this packet;

If 7.2.2. the neutralization of the forwarding queue of WSID node and WSID label bunch head has sent in buffer memory and do not had this packet, WSID node and a WSID label bunch head forward this packet, go to 7.3;

7.3.WSID node and WSID label bunch head select a uploading nodes as down hop routing node from upload queue, and by package forward, to this node, and turn-on data transmission timer Timer5, waits for replying of next-hop node;

7.3.1. the data transmission timer Timer5 time arrives, also do not receive and reply, WSID node or WSID label bunch head are chosen in addition a node as down hop routing node from uploading nodes queue, by package forward to this node, and turn-on data transmission timer Timer5, wait for replying of this node;

7.3.2. the data transmission timer Timer5 time does not arrive, and just receives replying of down hop routing node, timeing closing device, and WSID node and WSID label bunch head continues to keep the state of intercepting;

7.4. down hop WSID node and a WSID label bunch head are received after packet, carry out data retransmission by the method described in step 7.3, until packet is sent to WSID gateway;

7.5. root node is that WSID gateway is received after packet, checks forwarding queue and has sent in buffer memory whether have this packet, if do not exist, forwards this packet to WSID via node.

Communication mode between WSID label bunch head and WSID label bunch member is point-to-point propagation, and WSID label bunch member is directly sent to signal WSID label bunch head.

The MANET algorithm using has effectively utilized the advantage that cluster algorithm, Time Synchronization Mechanism and the network topology structure of WSID label are brought, and has formed reliable route.At the second layer of net topology structure, WSID label is divided into WSID label bunch head and WSID label bunch member by cluster algorithm, and the networking mode adopting is point-to-point transmission, and signal is directly sent to WSID label bunch head by WSID label bunch member; At the ground floor of network topology structure, pass through Time Synchronization Mechanism, formed respectively taking WSID node and WSID label bunch head as child node, the tree-shaped route taking WSID gateway as root node, each nodes records belong to self father node and child node (be uploading nodes and under pass node).
