The adaptation layer is always used when sending the data over PHY and MAC layers. For example, how an IPv6 packet is encapsulated in an Ethernet frame is defined by RFC2464. It is also the same for IEEE 802.11 Wi-Fi. RFC 6282 defines how an IPv6 data frame is encapsulated over an IEE 802.15.4 radio
Internet and other networks nowadays is based on IPv4 with 32-bit addresses, which limits the address space to 4,294,967,296 unique addresses. While the addresses were assigned to users, the unassigned addresses will naturally be decreased. On 3rd Feb 2011, the IPv4 address exhaustion has occurred while it had been delayed by address changes such as
The uplink to the Internet is handled by the Access Point (AP) acting as an IPv6 router. Several different devices are connected to the AP in a typical setup, such as PCs, servers, etc. The 6LoWPAN network is connected to the IPv6 network using an edge router. The edge router handles three actions which are:
This post is about the Advantages, Disadvantages, and protocol stack of the 6LoWPAN As we know, the open standard defined in RFC 6282 allows IPv6 packets to be passed from the 6LoWPAN network. It used with IEE 802.15.4 in a 2.4 GHz band. Other networking media such as sub-1 GHz low power RF, PLC, Bluetooth
IPv6 over Low-Power Wireless Personal Area Networks or 6LoWPAN for short is originated from the concept that even the smallest devices should also have an access to the Internet Protocol. These smallest devices or low-power devices with limited processing capabilities should be able to participate in the Internet of Things as well. The 6LoWPAN group
