Energy-Balanced Routing Protocol with QoS Constraints in Ad Hoc Network

摘要

With the rapid growth of mobile computing and intelligent terminal services, ad hoc network has been developed rapidly in the field of wireless communication and is considered as an important supplementary form of 5G, because of its self-organization and high spatial multiplexing rate. Since the increasing volume of mobile traffic, battery-powered mobile terminals are faced with severe challenges in terms of energy efficiency and QoS. In this paper, an energy-balanced routing protocol with QoS constraints is designed based on AODV protocol. Energy balance is realized by selecting nodes with higher residual energy of nodes to forward packets, and the objective function is established by using bandwidth and path length to realize the QoS constraints. The simulation results show that the improved routing protocol has been effectively improved in terms of the ratio of energy exhausted nodes, end-to-end delay, packet delivery rate, normalized routing overhead, and so on.
