Power consumption of MHR is higher than MTPR because MHR takes a path that tries to minimize number of nodes to reach to destination.
This way, MTPR reduces the overall transmission power consumed per packet, but it does not directly affect the lifetime of each node.
The energy-efficient routing is known as Minimum Transmission Power Routing (MTPR).
As similar step of DSR done in MTPR. But the choosing a path is based on minimum residual power node.
ZRP shows the best performance with maximum network lifetime than EPAR, MTPR and DSR.
Fig5 shows the throughput of ZRP, DSR protocol becoming stable when the number of nodes exceeds 70 while the MTPR increases significally.
If then Q [intersection] A [not equal to] O we apply the MTPR algorithm in order to select the best route.
As Q [intersection] A [not equal to] empty, then apply MTPR on [R.sub.3] and [R.sub.4] in order to select the best route (since both satisfy the required residual battery power, either [R.sub.3] or [R.sub.4] can be chosen).
EOEDR provides an appropriate combination of MTPR or MDR based on their threshold values to select the best route.
Hence, MTPR behaves exactly like the protocol using min-hop paths, because the shortest path minimizes the total transmission power consumed per packet.
In static environment, the behaviors of the MTPR and MDR mechanisms are evaluated when all nodes maintain their initial position throughout the duration of the simulations.
