Zebra black and white at birth. Plains and mountain zebra foals are protected by their mothers, as well as the head stallion and the other mares in their group. Grévy's zebra foals have only their mother as a regular protector, since, as noted above, Grévy's zebra groups often disband after a few months. Attempts have been made to train zebras for riding, since they have better resistance than horses to African diseases. While occasionally successful, most of these attempts failed due to the zebra's more unpredictable nature and tendency to panic under stress. For this reason, zebra-mules or zebroids (crosses between
Zebra Media Access Control node, the nodes it directly contacts (one-hop neighborhood) and what it can contact indirectly with an intermediate station (two-hop neighborhood) are known The neighborhood lists are given in an algorithm for allocation of time slot according to TDMA. The developers used the distributed algorithm DRAND. This algorithm ensures that no two indirect neighbors receive the same time slot. Zebra Media Access Control Zebra Media Access Control (Z-MAC) is a network protocol for wireless sensor networks. It controls how a Media Access Control (MAC) accesses a common communication medium of a network. Network protocols define specific details, such as how computers
