In this paper we propose an effective combination of a call admission control (CAC) mechanism together with a traffic scheduling algorithm. These two schemes are designed for WCDMA systems and operate in a complementary fashion in order to support handoff provisioning. The CAC mechanism belongs to the well known family of guard channel schemes and reserves(More)
The heterogeneous network (HetNet) deployed small cells technology to overcome the problems of holes “blind spots” coverage in 3G and 4G mobile networks. In this paper, we propose a hierarchical HetNet layout comprises of three layers, macro, metro and femto cells. The interplay between successive layers due to handover (HO) traffic is(More)
The advanced heterogeneous vehicular network (AHVN) is a new paradigm for future vehicular networks. AHVN is an integrated architecture between the VANET and the existing cellular wireless networks. This paper introduces a vehicular communications framework for efficient Multihop connectivity in AHVN. The vehicular communication in VANET is based on the(More)
In this paper, we propose a cooperative MAC scheme for vehicular connectivity in advanced heterogeneous vehicular networks (AHVN). AHVN is an integrated architecture between the vehicular ad hoc NETwork (VANET) and the existing vehicle to infrastructure (V2I) network. The proposed MAC is based on an adaptive backoff algorithm for accessing cooperative codes(More)
People have been utilizing Voice over Internet Protocol (VoIP) in most of the conventional communication facilities which has been of assistance in the enormous attenuation of operating costs, as well as the promotion of nextgeneration communication services-based IP. As an intimidating upshot, cyber criminals have correspondingly started interjecting the(More)
Cloud computing delivers resources and services through virtual machines on a pay-as-you-go basis. The allocation of storage space to users is usually determined by means of open allocation mechanisms that cannot guarantee an efficient allocation. Current allocation mechanisms do not consider user requests when making provisioning decisions. In other words,(More)
Advanced heterogeneous vehicular network (AHVN) is a promising architecture for providing vehicular services in the next generation of vehicular networks. AHVN is an integrated architecture between vehicular ad hoc networks and existing cellular wireless networks. In this work, we propose a Multihop vehicular connectivity model in V2V system, which depends(More)
