Abstract
Providing Quality of Service (QoS) for Mobile Ad Hoc Networks (MANET) is a challenging issue due to th e dynamic nat ure and limit ed res ources of such in frastructureless wireless net works. T his paper proposes a ne w approach f or supporting QoS in clus tered MANET. The proposed Cluster-Based QoS (CBQoS) pro vides MA NET with i nter-cluster/intra-cluster ser vice diff erentiation and aims to improve the overall performance of the network by increasing the overall network throughput and decreasing the overall end-to-end delay. CBQoS can be implemented as a standalone service differentiation system or be used wi th Differentiated Services (DiffServ) or o ther QoS m odels to enha nce Qo S provisionin g i n MANET. The simulation results show that the proposed approach achieves significant improvement in MANET's performance and QoS support.
