We model a cognitive radio system as a quasi-birth-death (QBD) process and determine its performance parameters. We also model the system at the quasi-stationary limiting regime. We show that this regime defines the ...
Opportunistic Routing (OR) is a new class of routing protocols that selects
the next-hop forwarder on-the-fly. In contrast to traditionally routing, OR does not select
a single node as the next-hop forwarder, but a set ...
