A broad class of Mobile Ad hoc NETwork (MANET) applications will require every mobile node in a connected subnet to establish persistent paths with a single sink or gateway or command-post. Temporally Ordered Routing Algorithm (TORA) is the only MANET routing protocol which has been explicitly designed to facilitate such a requirement. However, TORA has several shortcomings like the need for an expensive lower layer, the Internet MANET Encapsulation Protocol (IMEP); and substantial overhead in scenarios involving subnet partitions. The authors propose a novel protocol, Collision-Resistant TORA (CR-TORA), which is also designed to meet the same goal as TORA, viz., to lower overhead for establishing persistent paths from all nodes to a destination. However, CR-TORA overcomes the shortcomings of TORA.
