Our protocol uses the idea that a BSS can temporarily borrow an underused channel from a neighbor for the purposes of relaying packets.
In this paper, based on the latest advances in identity-based cryptography, we design a lightweight and cheat-resistant micropayment scheme to stimulate and compensate collaborative peers that sacrifice their resources to relay packets for other peers.
The IEEE 802.16j standard [1] includes support for RSs in IEEE 802.16 networks; while a number of articles, such as [2 4], consider IEEE 802.11 multi-hop networks, which allow transit APs to relay packets for mobile users.
When the PT is far from the PR, a secondary user, which has a better link quality and is not in transmitting or receiving mode, can be selected to relay packets for the PT.
These selected nodes are a sub-set of the entire sensor nodes and are selected based on constraints such as the hop relay allowed for relaying data packets.
Chopping up all communications into data packets of fixed size, and allowing machines to relay packets to each other, meant that there was no need for a direct link between every pair of machines on the network.
Matching the quality of channels, the destination in FANCC feedbacks which broadcast-packets to be selected for relay-packets and which terminals to relay, which costs 2 bits per terminal.
Despite source-destination channel quality, ANCC protocol allows all the broadcast-packets to be selected for relay-packets and all the terminals to attend relaying, which provides equal error protection to all the terminals.
Since the relayed packets can usually be transmitted at a high rate, the total packets that are necessary for decoding can be delivered to each destination node much faster than direct transmissions.
It also requests the next-hop address from network control unit for relaying the packet received from parsing and classification unit.
