 ==== Packet Frame ====
 [[File:S15_wirelessmesh_packet_frame.png|700px|thumb|right|text-top|Fig 9. Wireless packet frame]]
-The wireless packet frame is shown in figure 9. The packet frame is 32 bytes in length. It consists of a source address, destination address, hop address and data length which are 1 byte each and a 28 byte payload. The source address is the address of the transmitting node, the destination address is address of the destination node, hop address is the address of the next node which receives the data, the length field specifies the length of the transmitting data and the rest is the payload which is 28 bytes.
+The wireless packet frame is shown in figure 9. The packet frame is 32 bytes in length. It consists of a source address, destination address, hop address and data length which are 1 byte each and a 28 byte payload. To represent the payload length 7 bits are enough and MSB bit in length using to indicate whether we required an ack or not. The source address is the address of the transmitting node, the destination address is address of the destination node, hop address is the address of the next node which receives the data, the length field specifies the length of the transmitting data and the rest is the payload which is 28 bytes.
 Both ''hello_packet()'' and ''data_packet()'' will have the same packet frame format. A significant thing to be noticed is that, ''hello_packet()'' will have its destination address as broadcast address i.e. 0xFF since it is used to locate the nodes which are in its communication range.
