Design and Analysis of Cooperative Broadcast Scheme Based on Reliability in Mesh Network

Table 3

Implementation steps of SW-HBH-CARQ protocol.

---

Step 1: the parent starts to broadcast the packet (ID. j) and initializes i as 0.

Step 2: the subterminal judges whether the packet is successfully received. If so, it advances to step 3; otherwise, it advances to step 4.

Step 3: the subterminal forwards the data and returns the ACK to parent; then, it advances to step 5.

Step 4: the subterminal waits for the cooperation data from siblings. If the subterminal receives correct data, it returns to step 3; otherwise, it advances to step 5.

Step 5: the parent judges whether it receives the ACK, if so, ; otherwise, .

Step 6: after a data transmission cycle, if , then , if , then , and it returns to step 1.
