To adapt with the frequent link failures in mobile ad-hoc networks, the routing protocols shall catch more than one route, at least two routes. In case of two routes, the first route can be used as the main route; while the other one can be used as a standby route used upon the detections of link failures. If this is the case, the packet losses are virtually decreased to zero, and seamless multimedia communications can be supported over mobile ad-hoc networks. To ensure the existence of two routes between any randomly chosen two nodes, the node density in terms of the number of neighbors must be above a certain threshold. In this paper, we propose a mathematical model to find such node density, and propose some solutions in case the node density is below the required density in order to increase it to the required node density. Our results show that the probability to have two routes rapidly increases with node density till it reaches the saturation region, where the increase of node density has negligible improvement in terms of network availability. This paper shows that the network nodes must have at least 16 neighbors in order to ensure the existence of two routes between any randomly chosen source and destination pair.
