If the nearest neighbor nodes distance is less than the interference range
of a receive node, there will cause very strong inter-WBANs interference.
Among his topics are EMC analysis and survey, interference types, interference from both transmitter and receiver, calculating the received interference level, the interference range
and the reception range, coupling between antennas, near-field, the probability of frequency difference, and pulse interference to digital communications.
r' refers to the maximum distance from the transmitter that the transmitted signal causes interference on an unintended receiver.
Section 5 defines interference range
and carrier sensing range for fading channels and proves their scaling laws and applications.
where [d.sub.f] is forward packet delivery ratio, [P.sub.max] is the maximum tolerable interference at the receiver, Pr(1) is interference power from an interfering node l, [beta] is a parameter satisfying 0 [less than or equal to] p [less than or equal to] 1, and v' is the set of nodes in the interference range
In addition, we suppose that the radios of the nodes are equipped with omnidirectional antennas characterized by the same transmission range and the same interference range
. Node x is directly connected to node y and forms a wireless link, if and only if node y is within the transmission range of node x and they share a common channel.
Here [d.sub.R] is reception range--distance in which receiver can receive packet from transmitter and [d.sub.I] is interference range
- within such distance from receiver any single transmitter can interrupt ongoing transmission.
The result is that the area of study can be widened without losing the resolution level--limiting the interference range
with a single bi-prism would hurt resolution.
Pertinent Data: The non-electrostatic head eliminates the interference range
and features heightened damage reduction mechanisms, using both spring recovery and shear pin methods to absorb impact.
Sources of interference range
from mobile phones and high-definition satellite broadcasts to a communication project employing airships being promoted by the Public Management, Home Affairs, Posts and Telecommunications Ministry.
For simplicity, we assume that each PU has a fixed interference range
Transmission range was set to 60 and 70 m, and interference range
was 100 m.
