RSU-Aided Optimal Member Replacement Scheme with Improved Mobility Prediction for Vehicular Clouds in VANETs

Round 1

Reviewer 1 Report

This paper proposes a RSU-aided optimal member replacement scheme 80
based on an improved mobility prediction of vehicles for vehicular clouds in VANETs.

strength points:
-the study contributions are relatively novel.
- the network model of the proposed scheme is clearly defined in section 3, furthermore, the challenges are highlighted.
- Notations are well defined which makes it easier to read and understand the equations
-the proposed system is well validated by extensive traffic simulation in different scenarios.

weaknesses:
-the proposed system is compared only to 1 scheme (SERVitES)
-the following related works are missing:

-study limitation and future directions section/subsection is missing

Reviewer 2 Report

The paper deals with an interesting topic but several points must be considered to improve the presentation of the paper:

- Abstract is too long with general comments. I suggest focusing in novelties and results

- Section 1 is too long considering that there is a section 2 with the state of the art

- Large groups of references such as [3-14] must be aoided and expalined more individually

- At the end of sections 1 or 2, include some more explanations of the contributions.

- Results are based on simulation. Discuss the limitations that could be found when applying in real scenarios

-Section 7 is not necessary
