Comparative Analysis of QoS Routing Protocols in MANETS: Unicast & Multicast

In mobile ad hoc networks (MANETs), the provision of quality of service (QoS) guarantees is much more challenging than in wire line networks, mainly due to node mobility, multi hop communications, contention for channel access, and a lack of central coordination. The difficulties in the provision of such guarantees have limited the usefulness of MANETs. in the last decade, much research attention has focused on providing QoS assurances in MANET protocols. In this paper we have analysed different types of routing protocols and QoS metrics in MANETS.
