2. doc.: IEEE 15-14-0200-00-0008 Submission MAC Technical Issue Our proposal for CFC is too heavy for integrating a small chip. –Do we need consider heavy protocols including routing, security in MAC layer? Multi-hop and Security functions is needed for PAC as the TGD (15-12- 0568-07-0008) Slide 2 Jeongseok Yu et al., Chung-Ang University

3. doc.: IEEE 15-14-0200-00-0008 Submission MAC Technical Issue Routing? –Multi-hop supporting technique is needed for PAC as in TGD documents. –It needs for multi-hop unicast/multicast transmission (multi-hop supporting). –Flooding for multi-hop supporting occurs implosion problem. (we will provide simulation result based on TGD in the May meeting)., Slide 3

4. doc.: IEEE 15-14-0200-00-0008 Submission MAC Technical Issue Security? –Our proposal provides security modes (no security, security enable mode). –Security function is needed for PAC as described in TGD documents. –Security is essential requirements for peering procedure in the PAC. –Other standard (e.g., WiFi, Zigbee) also provides security function., Slide 4
