Redundant Transmitter Placement in Rural Areas for User-to-User Communication in Green Computing

In User-to-User (U2U) communication in a Green Smart Cloud, a smartphone carried by a user can work as a transmitter. However, in some areas having only a handful of people, such as rural areas, smartphone-based transmitters can be scarce. Given that they should be placed at about every 100m
²
to be used for U2U communication, the placement of standalone transmitters at strategic points is significantly important. Moreover, estimating the minimum number of transmitters to cover the whole area to achieve network energy efficiency and quality of service (QoS) is crucial. This paper presents optimal redundant transmitter placement for U2U communication in a Green Smart Cloud to achieve QoS. Experimental results show that two redundancy, where at least two transmitters cover every point on the network, is more reliable than no redundancy and more cost effective than three redundancy, where at least three transmitters cover every point on the network.
