Goal | DAT | TLC | Delay | PDR | Energy Cons. | Strength | Weakness |
|
TLE based | ATLAS (2011) | To reduce energy consumption and delay, increase packet delivery ratio | Yes | Yes | Low | High | Low | Improve energy efficiency and throughput | Traffic prioritization is ignored |
PLA-MAC (2013) | To achieve energy efficiency with prioritization based traffic load awareness | Yes | Yes | Low | High | High | Reduce delay and increase PDR | Ignore diverse traffic loads |
MDTA-MAC (2014) | To improve energy with low delay with traffic load management | Yes | Yes | High | Medium | Low | Improve energy efficiency and PDR | Delay increases due to increase in traffic load |
|
AWI based | TAD-MAC (2012) | To improve energy efficiency with traffic adaptive approach | Yes | No | NC | NC | Low | Improve energy efficiency | Inappropriate for WBANs due to its preamble-based approach |
TaMAC (2012) | To improve energy efficiency and QoS for diverse traffic with low delay | Yes | No | High | NC | Medium | Improve energy efficiency | Time-critical traffic is delayed by the wake-up response signal and beacon sending time |
HS-MAC (2016) | To improve energy efficiency by using traffic-based adaptive wake-up Interval | Yes | No | Low | Low | Medium | Improve energy efficiency with low delay | Packet loss ratio is increased in the worst case |
|
ATSA based | LDTA-MAC (2011) | To reduce delay and power consumption with the management of diverse traffic loads | Yes | No | Low | High | Low | Adaptive slot allocation based on traffic load | Fixed CAP reduces energy efficiency during low load and throughput during high load |
CA-MAC (2013) | To improve energy efficiency and to reduce delay with real-time diverse traffic management | Yes | No | Low | High | Medium | Reduce delay and improve PDR | No traffic load estimation |
Stat-MAC (2013) | To improve energy efficiency with low delay by providing a scheme for the retransmission of lost messages during inactive period | Yes | No | Medium | NC | Low | Improve energy efficiency | Experiment based on two sensor nodes and delay increases by the increment in timeline(s) |
CAC-MAC (2013) | To achieve energy efficiency with prioritization traffic load based resource allocation | Yes | No | Medium | Medium | Low | Improve energy efficiency | No traffic load estimation |
Ada-MAC (2015) | To reduce packet loss ratio and packet collision ratio with the adjustment of dynamic traffic loads | Yes | No | Medium | Medium | NC | Reduce delay and improve PDR | Multiple queues for diverse traffic prioritization is not a practical approach for WBANs |
CoR-MAC (2016) | To reduce the transmission delay of emergency data | Yes | No | Low | High | Low | Reduce data delivery delay and shows better delay performance that is improved from 50%–85% | The average delay of non-time-critical data increases by the increasing number of nodes |
