Multipath Fault Tolerant Routing Protocol in MANET
V. Jayalakshmi · International Journal on AdHoc Networking Systems · 2012
Mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes which dynamically exchange data among themselves without the reliance on a fixed base station or a wired backbone network and it the makes the routing a crucial issue to the design of the MANET.Multiple path routing protocols are shown to be performance-effective alternatives over single-path routing for ad hoc networks and it represents a promising routing method for wireless mobile ad hoc networks.Multi-path routing achieves load balancing and is more resilient to route failures..In this paper we propose an energy efficient multipath fault tolerant routing protocol to improve the reliability of data routing in Mobile ad hoc networks.The proposed RFTA is a multi objective routing protocol that meets diverse application requirements by considering the changing conditions of the network.The efficiency of the proposed protocol has been evaluated on different scenarios and there has been a noticeable improvement in the packet delivery ratio and also in the reduction of end-to-end delay comparing to SMR,SMS and MDSR.
