A Path Connection Availability Model for MANETs with Random Waypoint Mobility

Understanding the factors that affect the path connection availability in multi-hop ad hoc networks can help to understand the path stability under various degrees of system dynamics. In addition, the connection availability of paths can be used as a global measure for the performance of ad hoc networks. To the best of our knowledge, there is no analytical study that provides a closed form solution for analytical analysis of connection availability of paths in multi-hop ad hoc networks with random waypoint mobility. This work proposes a closed form solution for this problem using a new stochastic reward net model. The influences of different factors, such as the number of nodes in the network, transmission range, network area size, data transmission rate, and routing protocol on the path connection availability are investigated. The proposed model is validated by extensive simulations.
