s | The source node |
t | The sink node |
h | The current node |
| Distance from source node to sink node |
D h→t | Distance from current node to the sink node |
T hop | The average hop delay at a sensor node |
T QoS | The application-specific end-to-end delay objective |
T h→t | The reserved time credit for the data delivery from current node to the sink node according to TQoS |
t s→h | Data packet's experienced delay up to current node |
H h→t | The desired hop count from current node to the sink node according to TQoS |
D hop | The desired hop distance for next-hop-selection in MGR |
E hop | The energy consumption for one-hop data delivery |
E ete | The end-to-end energy consumption for a successful data delivery |
