Cooperative Diversity With Mobile Nodes: Capacity Outage Rate and Duration

The outage probability is an important performance measure for cooperative diversity schemes. However, in mobile environments, the outage probability does not completely describe the behavior of cooperative diversity schemes since the mobility of the involved nodes introduces variations in the channel gains. As a result, the capacity outage events are correlated in time and second-order statistical parameters of the achievable information-theoretic capacity such as the Average capacity Outage Rate (AOR) and the Average capacity Outage Duration (AOD) are required to obtain a more complete description of the properties of cooperative diversity protocols.
