This paper proposes a session state aware (SSA) handover procedure to solve the problem of seamless mobility in heterogeneous wireless networks. The novelty of the proposed SSA procedure is the alignment of the network layer handover execution instant with the callee's voice over Internet protocol (VoIP) session silence period. The effectiveness of the(More)
Cyclostationary detector (CSD) is one of the spectrum sensing techniques used in cognitive radio. Although it has a superior performance in Gaussian environments, its performance severely deteriorates in non-Gaussian environments. This paper proposes a novel dynamic CSD-based algorithm that jointly utilizes the generalized seasonal block bootstrap (GSBB)(More)
Traffic offloading among coexisting heterogeneous radio access technologies (RATs), i.e., inter-RAT offloading, is considered an effective strategy for enhancing the capacity of wireless networks and reducing the power consumption of both base stations (BSs) and mobile stations (MSs). To fully utilize inter-RAT offloading advantages, a mobility-aware(More)
