TORA(Temporally Ordered Routing Algorithm)-Based Multi-Path Routing Algorithm for Mobile Ad Hoc Networks M-TORA

M-TORA is a new multi-path routing protocol based on temporally ordered routing algorithm(TORA) proposed for mobile Ad hoc networks(MANET).When a node has multiple down streams,M-TORA can take not only the routing hop count but also packet queue length of MAC layer into consideration,by adding information of MAC layer into the Internet MANET encapsulation protocol(IMEP) control packet header field.Accordingly,M-TORA can lead to better down stream than TORA.M-TORA makes use of probabilistic routing selection strategy and can spread network loads on multiple routing paths and consequently automatically balance the network loads.In simulations based on OPNET it was shown that M-TORA could outperform the classical TORA in decreasing delay and improving the network packet delivery ratio.
