An Efficient Multi-Constrained Feasible Path Selection for Manet

Quality-of-Service (QoS) routing in an ad-hoc network is difficult because the network topology may change constantly and the available state information for routing is inherently imprecise. This paper proposes a method for multi-constrained feasible path selection for MANET. The authors introduce the composite function which allows OLSR to find the feasible path in case of multiple routes is available to reach the same destination. Combinations of additive and non-additive QoS metrics are considered to find the best path. They simulation results show that the QoS version of the OLSR do improve the packet delivery ratio, throughput, normalized control overhead, end-to-end delay and packet loss but with the increased time complexity.
