Correction to: Peer-to-Peer Netw. Appl. https://doi.org/10.1007/s12083-020-00933-2 The Publisher would like to correct the introduced formatting errors and presentation of equation 4 and Table 2 in the original publication. 1. Eq. 4 is typeset inappropriately by inserting unnecessary commas and may confuse the reader. 2. In Table 2, some values of the two columns are mistakenly shifted. First, the Parameters with the Experimental setup in the first row of the table must be changed. “Network area size,
Data packet size, Control packet size, Transmission layer protocol, Number of network nodes, Nodes distribution pattern, The initial energy of nodes, and Eelec” should be moved to the left column, as well as their values, move to the bottom right of the table. The Publisher apologizes for the oversight and for any confusion it may have caused. The original article has been corrected and the updated equation 4 and Table 2 are presented in this article.
