Ad Hoc Networks: Cross-Layer Issues

Adaptive QoS Routing by Cross-Layer Cooperation in Ad Hoc Networks

QoS provisioning is a complex and challenging issue in mobile ad hoc networks, especially when there are multiple QoS constraints. In this paper, we propose an adaptive QoS routing scheme supported by cross-la...

A Cross-Layer Route Discovery Framework for Mobile Ad Hoc Networks

Most reactive routing protocols in MANETs employ a random delay between rebroadcasting route requests (RREQ) in order to avoid "broadcast storms." However this can lead to problems such as "next hop racing" an...
