Comparison of Multipath Routing Protocol for Mobile Ad hoc Network

MANETs are networks that do not depend on any infrastructure during its working. They are considered as an infrastructure less network, so the cost of this type of networks is less in comparison to other traditional networks. The routing is one of the most important challenges in MANET systems. A Cross-layer design among Network, MAC and Physical layers based on Threshold Multipath Routing Protocol (CTMRP) is proposed. CTMRP is designed for decision maker based on threshold value of average paths signal for efficient transmission of the Text, image, audio and video. Protocols that rely on cross-layer interaction between several levels have become more prevalent in an attempt to enhance MANET performance.
