—In the literature, several Interference-Aware Multi-path Protocols have been introduced for Mobile Ad hoc NETworks (MANETs) but they are either not highly efficient or have the computational complexity of NP-hard. To tackle the problems, in this paper, we propose a novel Source Routing Interference-Aware Multi-path Protocol (SR-IA-MPOLSR) for mobile ad hoc networks. Our protocol uses source routing mechanism, parallel transmission via the minimal interference paths and adapts quickly to the change of topology in MANETs. The other strong point of SR-IAMPOLSR is that it finds paths with the computational complexity in polynomial time instead of NP-hard of other protocols. We compare our protocol to two typical protocols AOMDV (multipath protocol) and DSR in terms of packet delivery fraction, end-to-end delay, and routing overhead when the RTS/CTS mechanism is alternatively enabled and disabled. From simulation results, we show that SR-IA-MPOLSR significantly improves the network performance. We also prove the the network performance is reduced when RTS/CTS mechanism is used.
