Load aware routing metrics capture the traffic concentration and congestion parameters at node level to introduce load awareness in the routing which has a significant effect specially in multi casting and real time applications, i.e., VoIP and Video over IP in community networks.
Study revealed that load & interference aware cross layer routing metrics are more efficient to pick up link quality parameters as compared to simple, interference, and load aware routing metrics in highly congested traffic areas especially in real time applications like VoIP and Video over IP in multi casting and peer-to-peer service models.
Birch's means may be modest (Revolt had a multi-casting cast of six), but her ideas are big.
Using optimization methods, the precoder design of RS at finite SNR was investigated in [28] for the sum rate and rate region maximization with imperfect CSIT, in [32] for max-min fair transmission with imperfect CSIT, and in [34] for multi-group multi-cast with perfect CSIT.
Figure 1 The multi-cast system model.
Section 2 presents the multi-cast system model and the joint power allocation-based mathematical model.
The WSR achieved by the multi-cast scheme is the worst.
Other important works are focused on scheduling in vehicular DTN [19], multi-cast solution [20, 21].
In fact, the multi-cast system is widely used in wireless communications, where the physical-layer network coding can be applied since the nature of broadcast is available for PLNC in the multi-cast model.
In [24], a limited-feedback relay selection algorithm is also proposed and investigated for a multi-cast relay network.
The entire platform is configured through a bus-based configuration infrastructure that implements unicast, multi-cast, and broadcast mechanisms.
