SPECIFIC COMMENTS & SUGGESTIONS (to be made available to the author(s)): ------------------------------------ The paper addressed signaling and routing protocols in Integrated Cellular and Ad Hoc Relay (iCAR) systems. Three protocols were proposed to establish QoS guaranteed connections in iCAR. Protocol 1 is a centralized protocol, and protocol 2 and 3 are both distributed. Signaling overhead analysis of three protocols was discussed and simulations were further conducted. The issue is interesting and the paper is well written. But there are still some problems: 1. After a route has been established between the source (e,g., MH) and the destination (e.g., BTS) via primary relaying, what the system will do if some links on the route are failure? Although it assumes that ARS has low mobility, the movement of MH or hash enviroment may cause the failure of links. Fault-tolerance should be considered in such protocols that are used in iCAR. 2. In Fig. 12, the ARS's are randomly placed in the donut-shaped regin of the center cell. The assumption was adopted again in the simulations. But authors did not give any reason and explanation. Why the positions of ARS's are bounded between these two circles? And radiis of the two circles are set to 2500m and 1000m, respectively, in the simulations. Is there any reference? 3. QoS considered in this paper only concerns required bandwidth. Delay is another important issue which should be considered, especially in the secondary relaying. 4. So many notations are used in the paper. What 'BTS' stands for is not given in the paper. I only found the explaination of BTS in Abstract. III.
