Direct connectivity means one-hop connected links between nodes, namely, these nodes could communicate with each other directly, and there does not need relay nodes as shown in Figure 4. Indirect connectivity consists of multi-hop forwarding and store-carry-forward.
Further, only depending on direct connectivity, i.e. one-hop connected links between vehicles, is far from the continuous growing communication demands in VANETs, such as inter-vehicle amusement, cooperative collision avoidance, inter-vehicle emergency notification etc.
Consider a network ([N,L]) of nodes N and directed links L, which consists of a finite sequence of connecting links with a certain orientation.
With direct connect, customers can establish their own private links to Google without using an intermediary network.
"The direct connect of retail is great.
The clustering coefficient is defined as C i = 2 n/ k i (k i – 1), where n is the number of direct links connecting the k i nearest neighbors of node i.
Although a number of proteins with Ca2+ sensing domains have been implicated in SV endocytosis (synaptotagmin, calmodulin, calcineurin) direct links connecting endocytic behavior to consequences of Ca2+ sensing have not been established.
Clustering coefficient (CClu) is defined as where n denotes the number of direct links connecting the K i nearest neighbors of node i. C Clu ranges from zero (for a node that is part of a loosely connected group) to one (for a node at the center of a fully connected cluster).
Clustering coefficient (C Clu) is defined as where n denotes the number of direct links connecting the K i nearest neighbors of node i. C Clu ranges from zero (for a node that is part of a loosely connected group) to one (for a node at the center of a fully connected cluster).
