Even for small sites (and maybe mostly for small sites) this will provide a useful communication mechanism unavailable today.
Emergency response during disasters is often complicated because communication becomes unavailable.
On the contrary, in the local scenario, communication infrastructures are unavailable and each mobile node can collect the locations of other nodes only within its direct communication range.
Difficulties with communication such as unavailable emergency phone lines, prolonged admitting time due to paperwork before emergency care is provided and poor medical records systems, also contributed to difficulty accessing the system.
Our original scheme also demonstrates that, by means of offline communicated coexistence requirements to be statistically satisfied by both networks, i.e., MANET interference underestimation and overestimation constraints imposed, respectively, by the primary and secondary networks, the unavailable online communication between both networks can be surprisingly counterweighted.
The algorithm also proves to be effective when the communication channel is imperfect (periodically unavailable).
Real-time communication may not be readily unavailable in many terrestrial settings as well, or may be limited to voice or off-line file exchange.
Poor or unavailable transport and communication was observed at all the visited facilities and this hindered effective delivery of PHC.
Some of the challenges are inadequacy of supplies, shortage of personnel, poor quality of infrastructures and unavailable transport and communication equipment.
