摘要:The increasing popularity of using multimedia and real time applications in different potential commercial in MANETs, make it logical step to support Quality of Service (QoS) over wireless network. QoS support is tightly related to resource allocation and reservation to satisfy the application requirements; the requirements include bandwidth, delay, delay-jitter and packet to loss ratio. One of the notoriously difficult problems in QoS routing in Mobile Ad-hoc Networks (MANET) is to ensure that the established path for a connection does not break before the end of the data transmission. In order to reduce the number of broken routes, a novel reliable routing algorithm using fuzzy applicability is proposed to increase the reliability during the routing selection. In the proposed algorithm source chooses a stable path for nodes mobility by considering nodes position/ velocity information. Also we propose novel method for rout maintenance, in this protocol before breaking packet transmitted path a new one is established. The simulation results show that the algorithm can reduce the number of broken routes efficiently and can improve route stability and network performance effectively.
