Multipath Bandwidth Splitting Reservation in Ad Hoc Networks

This paper proposes a novel bandwidth reservation mechanismn called the Multipath Bandwidth Splitting Reservation (MBSR) for ad hoc networks. In MBSR, an overall bandwidth request is split into several smaller bandwidth requests, and these requests will be reserved on multiple disjoint paths respectively. Both theoretical analysis and simulation results prove that the probability of successful reservation of MBSR is higher than that of single-path reservation. In addition, simulation results show that the MBSR can improve the reserved packet ratio of QoS traffic, the packet delivery ratio and the end-to-end delay of both best-effort traffic and QoS traffic.
