In this method, which is proposed for a circular area surrounding a sink, one hop communication between the cluster heads and the sink is replaced by an optimal multi-hop communications.
It is focused on increasing the awareness of the status of the low voltage power distribution network through an optimal and interoperable communications architecture which provides detailed information on customers' consumption and generation.
Additionally, the proposed design defines a set of route optimization procedures, allowing compliant devices to use the optimal data path for media communications.
This sub-optimal route (lack of route optimization) considerably reduces the communications performance, increases the delay and the infrastructure load.
Psychologist Penelope Leach, author of The Essential First Year, said: "A baby's optimal brain development depends on communications between his 'emotional brain' and his mother's immediate and sensitive responses.
This study focuses primarily on the delay guarantee and optimal delay aspects of wireless communications.
However, the optimal TP for the group communications with the DL coverage and the UL transmission has not been studied.
Power allocation is used to maximize sum utility derived from a wireless network operation to yield throughput optimal, fair, and energy-efficient communications.
Besides that, we also obtain the successful transmission probability (STP) for the two considered communications, and the optimal values of time switching (TS) and power splitting (PS) ratios are achieved with the help of a genetic algorithm (GA -based optimization alGA -basedn optimization energy halgorithm (EH) protocol so-called Hybrin TS-PS (HTPS) relaying prourcol.
Finally, in the context of cooperative communications, we derived asymptotically optimal power allocations for relay channels which were showed to provide gains on the whole SNR range.
