Energy, delay and hop count multi-constraints QoS routing algorithm for wireless ad-hoc networks
Hussein M. El Attar, Mohamed Ibrahim El-Emary · 2017
QoS configuration is needed to sustain the global network needs as Maintaining Max Network Throughput, Minimum Network energy consumption, Assigning Specific Profiles upon Organization's Request and Targeting Prioritizing Service Delivery Based On the constraints Faced. This paper will introduce an optimization solution for multi-constrained routing problem to assess the potential benefit of QoS routing. Multi Constrained Routing Algorithm (OMCR) will be analyzed throughout the paper, including simulation results done by Network Simulation program (NS2). The paper also compares its advantages over other routing algorithms. The OMCR main disadvantage is that it deals with constraints separately while fetching best path to the destination; this barrier prevents the network from dealing effectively with multi constraint behavior. In this paper, Advanced OMCR (A-OMCR) protocol is proposed to optimize the quality of service parameters such as energy, delay and hop count. The main aim of A-OMCR is fetching a feasible path from source to destination while optimizing multiple QoS constraints simultaneously to overcome the primary disadvantage of OMCR Algorithm.
