Survey on QoS for Multi-path Routing protocols in Mobile Ad-Hoc Networks

MANET (1) is a self-configuring network of mobile devices. These devices (nodes) are free to move independently in any direction and will therefore change its links to other devices frequently. Because of multi-hop routing requirements MANET nodes need to act as both host as well as router at a time and perform all the routing and state maintenance operations (5). Routing has always been one of the key challenges in Mobile Ad Hoc Networks and the challenge become more difficult when the network size increases (13). This paper gives the survey of multi-path routing protocols for Mobile Ad-Hoc networks. Also future work is suggested where different Quality of service parameters for routing protocols is suggested.
