Abstract—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. We introduce the composite function which allows OLSR to find the feasible path in case of multiple routes are available to reach the same destination. Combinations of additive and non additive QoS metrics are considered to find the best path. Our 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.
Keywords-MANET,OLSR (Optimized Link State Routing), Multi-constrained QoS Routing.
Introduction
A Mobile Ad Hoc Network is a set of mobile nodes that are equipped with wireless transmitters and receivers which allow them to communicate each other without the infrastructure. Since there is no infrastructure is used for networking the central administration for the network is not required. Each transmitter has a limited effective range; the nods within the coverage are able to communicate directly otherwise the nodes are communicated through a multi-hop basis. There are number of applications for this type of network. A group of moving soldiers in a battlefield communicates and coordinates with each other. A group of people with portable computers share their data in a conference room without laying cables between them.
Mobile ad hoc networks have primarily been
