Performance Evaluation of ACO Algorithm Based Multirouting Protocol to Improve QoS

Mobile ad hoc network (MANET) is an autonomous and self-configuring system connected by wireless links. It is a collection of mobile nodes and is widely used where network establishment is challenging. Wireless ad hoc network makes available multiple paths for data transmission, but it is necessary to choose most efficient path and provide better Quality of Service (QoS). Due to frequent movement and formation of dynamic connections in MANET, it is challenging to maintain quality of service. This QoS is inspected using performance matrices such as end to end delay, bandwidth, throughput, probability of packet loss, delay variance (jitter) etc. A new protocol QoS enabled ant colony optimization based multipath routing protocol (QAMR) is proposed based on an ant colony optimization algorithm which provides plausible path out of multiple paths for data transmission. This algorithm is scalable, adaptive and efficient. The performance is evaluated by comparing QAMR protocol and AODV protocol using network simulator.
