On the other hand, LRF, as its name implies, forwards the bundle that has not been forwarded over a certain period of time.
As a result, the data frames can be forwarded over multiple hops in a single beacon interval, and the end-to-end delay in the multi-hop transmission is decreased efficiently.
In one email exchange dated June 2011, Clinton instructed her top policy advisor Jacob Sullivan to send her talking points — which were scheduled to be forwarded over the State Department's secured network — over a non-secure fax line.
In a blog, Context Information Security states that 6 LoWPAN is a wireless communication specification built upon IEE 802.15.4, the same base standard used by Zigbee, designed to allow IPv6 packets to be forwarded over low power personal area networks (PAN).
These energy estimates are forwarded over noiseless channels to a fusion center (FC).
Multihop performance degradation, that is, the fact that traffic that is forwarded over multiple hops receives only a fraction of the throughput that a single-hop flow achieves, occurs because of the random access of the MAC protocol.
Because when a data frame is forwarded over multiple hops, only the next hop device is notified about the pending frame, devices on other hops may stay in doze mode and thus causes quite a long end-to-end delay.
The message is forwarded over the tree and, for every message that a node of the tree sends to one of its correct neighbor, it waits for the corresponding acknowledgement from this neighbor, confirming the reception of the message.
