Previous works on network coding capacity for wireless networks have taken the assumption that the network is stationary. In this paper, the mobility of ad hoc networks is considered as a key factor influencing network capacity, and a new and unified analytical expression of the capacity of a mobile ad hoc network applying network coding is derived under the two main mobility models, including random waypoint and random walk. The simulation results show that under the mobility condition, the network capacity of mobile ad hoc networks applying network coding still exhibits a concentration behavior around the mean value of the minimum cut.
