Table 6 Analysis of CSMA/CA with Aloha based slot allocation MAC protocols
MAC protocol | Data reliability | Energy consumption | Remarks |
|---|---|---|---|
U-MAC [53] | Low | High | The slot allocation is based on the contention and predefined time slot. The energy consumption is high which degrades the data reliability in terms of a higher delay with collision and does not acceptable for critical data |
AC-MAC [54] | High | Low | The patient’s data are distributed to different channels, but GM data cannot access the channel which has reserved for EM. This restriction improves the performance of MAC in terms of lower energy consumption with higher data reliability |
