Erratum to: Impact of the energy-based and location-based LEACH secondary cluster aggregation on WSN lifetime

Erratum to: Wireless Netw DOI 10.1007/s11276-016-1414-9

In the original publication, Equation 4.1 and the value of initial energy in Table 11 were wrongly published. The above-mentioned errors are corrected with this erratum.

• 1. In Equation 4.1, the correct expression as used in the simulations is given below:

  $$ E_{TX} = \left\{ {\begin{array}{*{20}l} {l \times E_{elec} + l \times \varepsilon_{fs} \times d^{2} } \hfill & {when\,\,d \le d_{0} } \hfill \\ {l \times E_{elec} + l \times \varepsilon_{mp} \times d^{4} } \hfill & {when\,\,d > d_{0} } \hfill \\ \end{array} } \right. $$

  (4.1)

• 2. For Table 11, the initial energy is 0.5 J as shown in Section 4.3, line 2.
