DMRM: Enhanced QoS using Dynamic Multipath Routing for MANETS

MANETS are Mobile Ad Hoc Networks having no infrastructure and is a crowd of mobile nodes, usually form a short-term network based on any requirement. Nowadays MANETS are used in widely in many applications due to the availability of the wireless devices. Quality of Service (QoS) is a more challenging concern in wireless networks and it is one of the most important difficulties in MANETs. Due to the battery power and frequent mobility of the mobile nodes the topology of the MANET is changed. It is necessary to have a dynamic multipath routing mechanism to improve the QoS of the Mobile Ad Hoc Networks. This paper proposed a novel dynamic multipath routing mechanism for MANETS which identifies an alternative path for data transmission when the when the bandwidth of the current link reduced to the given threshold or load delay of a node reduced to the given threshold. When compared to the single path protocol Optimized Link State Routing(OLSR), simulation results demonstrate that the proposed technique performs well in terms of average end-to-end delay and delivery ratio.
