FSNRP: Fuzzy-controlled priority scheduling of non-real time data packets in mobile ad-hoc networks

摘要

Mobile ad hoc networks (MANETs) is an infrastructure less network where topology is very dynamic and nodes are energy constrained. Therefore, scheduling for data packets transfer is very important. We can classify all the data packets into two categories - real time and non-real time. Scheduling of non-real time data packets should be different from real time data packet. Here timely delivery is not an important criterion to be met. The main intention here is to reduce the number of route request messages, as much as possible, through the scheduling policy. Therefore, high priorities are given to those packets which are travelling along fragile paths compared to those traveling along the stable paths. Moreover, when a communication session is on the verge of completion, its packets should be forwarded urgently. This scheduling algorithm FSNRP is designed to consider all these factors. The performance improvement it produces is very significant compared to other scheduling protocols.
