Review #27A
===========================================================================

Overall merit
-------------
3. Weak accept

Reviewer expertise
------------------
2. Some familiarity

Paper summary
-------------
The paper proposes a Deterministic Backoff-based MAC Protocol for UAV Networks.

Comments for author
-------------------
The approach presented in this paper is rather very simplistic. The reviewer is not sure if the assumption made and the backoff strategy work really work in practice in real world conditions, and under varied mobility settlings.

Review #27B
===========================================================================

Overall merit
-------------
2. Weak reject

Reviewer expertise
------------------
3. Knowledgeable

Paper summary
-------------
This paper presents deterministic backoff mechanism instead of binary exponential backoff for MAC protocol .

Comments for author
-------------------
The presentation of the paper is not satisfactory. There are multiple grammar issues in the paper. The writing needs to be revised. Motivation of the paper is not clear. Selection of deterministic backoff is not a good idea just for having fairness. The problem can be solved by selecting optimal sleep-wake policies for an energy harvesting sensor nodes.

Review #27C
===========================================================================

Overall merit
-------------
3. Weak accept

Reviewer expertise
------------------
4. Expert

Paper summary
-------------
A MAC protocol for WSNs where the data gathered by the sensors are uploaded to the network via a UAV flying over the region is proposed.

Comments for author
-------------------
1) In Algorithm 1, the symbol m is undefined. 
2) Similarly, the symbol U is undefined in Algorithm 1, though I guess from the context it can be inferred that it denotes a uniform distribution. If that is the case, then the title that the back-off is deterministic is misleading. The authors could consider clarifying what exactly is deterministic. 
2) Is there a typo in line 8 of the algorithm? The line simplifies to r <-- r. 
3) In Algorithm 1, the authors could consider clarifying the difference between the condition collision==1 (line 7) and success==0 (line 17). 
4) The authors could consider rewriting the description of the protocol, especially Step 4 of Section 3, for better clarity. This reviewer had to read it multiple times to understand, but it is still unclear.
