Abstract

This work analyzes the outage probability of a wireless cooperative network with a single helper selected from spatially random mobile helpers. We consider two representative scenarios, where the mobility of mobile helpers follows random direction (RD) and random way point (RWP). Exact analytical expressions of the outage probability are derived and validated by simulations. The analysis can be used to adapt helper selection based on statistics of mobile nodes and channel conditions to satisfy a quality-of-service requirement. The outage probability of RWP is found close to that of RD for a large relay area. Hence, it is reasonable to estimate the outage probability of RWP as in RD based on the assumption of a uniform node distribution.
