Detailed explanation-1: -6LoWPAN also provides a compression mechanism that reduces the IPv6 headers sizes sent over-the-air and thus reduces transmission overhead. The fewer bits are sent over-the-air, the less energy is consumed by the device.
Detailed explanation-2: -4 and characterized by short range, low bit rate, low power, low memory usage and low cost [6]. With the mechanisms provided by the adaptation layer, there are four basic header types defined in 6LoWPAN: Dispatch Header, Mesh Header, Fragmentation Header and the HC1 Header (IPv6 Header Compression Header) [7].
Detailed explanation-3: -The different routing protocols in 6LoWPAN are LOAD, MLOAD, DYMO-Low, Hi-Low, Extended Hi-Low, S-AODV, and so forth. Figure 5 shows the mesh-under and route-over routing. In this, the adaptation layer performs the mesh routing and forwards packets to the destination over multiple hops in mesh-under the scheme.
