“…It should be noted that one of the most important assumptions that determine the soundness and practicability of a proposed deployment approach are those in relation with the adopted communication model. The latter describes, in a binary [2], [6], [11], [12], [17] or probabilistic manner [3], [16], [22], [26], [28], the quality of a communication link between two nodes, according to a set of parameters, which group in most of the proposed approaches, the distance between the communicating nodes [2], [3], [11], [12], [22], the transmission range (power) of nodes [2], [3], [11], [12], [22], the obstacles [32] as well as the medium of transmissions (radio, acoustic, etc.) [3].…”
