Congestion Control and QOS Improvement for AEERG protocol in MANET

Abstract

QOS improvement has been a subject of intensive discussion. The research in the network field for congestion control is by means of scheduling packets from different traffic flows for processing at a specific node. When that particular node is selected for the transmission of all traffic flows since it has been chosen as an emerging node for the shortest path in the adaptive energy efficient algorithm, queue scheduling disciplines have been used to improve the quality of service. In this paper, we evaluate the performance of four queuing disciplines (FIFO, PQ, RED and WFQ) which is implemented in the AEERG protocol. This paper gives the NS-2 simulation results to compare their relative performance based on queuing delay, packet drop rate and end-to-end delay for the above queuing techniques.
