Dynamic Two-Tier Cell Structure for Bandwidth Reservation of Handoffs in Cellular Networks
نویسندگان
چکیده
To satisfy both the bandwidth efficiency of low-speed mobile hosts (MHs) and seamless handoff of high-speed MHs in cellular networks, this paper proposes a reservation scheme which exploits a dynamic two-tier cell structure and the handoff probability. The dynamic two-tier cell structure determines the reservation and non-reservation zones according to the speed of MHs. The handoff probability is calculated using the moving speed and the direction of MHs. key words: two-tier cell, dynamic reservation, handoff probability, adaptive bandwidth reservation

An adaptive bandwidth reservation scheme for 4G cellular networks using flexible 2-tier cell structure
Many mechanisms based on bandwidth reservation have been proposed in the literature to decrease connection dropping probability for handoffs in cellular communications. The handoff events occur at a much higher rate in packet-switched fourth generation mobile communication networks than in traditional cellular systems. An efficient bandwidth reservation mechanism for the neighboring cells is th...
متن کاملA Dynamic Bandwidth Reservation Scheme based on A Dynamic 2-tier Cell Structure in Cellular Networks
In multimedia wireless networks, when a mobile host (MH) moves to a neighbor cell, it requests the base station (BS) to reserve the bandwidth for seamless handoff. The reservation scheme based on the fixed 2-tier cell structure was proposed to prevent the reservation requests from the MHs close to the BSs. In this reservation scheme, the BS requests the reservation only when the MH is outside o...
متن کاملA comparative study of bandwidth reservation and admission control schemes in QoS-sensitive cellular networks
This paper compares five different schemes – called CHOI, NAG, AG, BHARG, and NCBF – for reserving bandwidths for handoffs and admission control for new connection requests in QoS-sensitive cellular networks. CHOI and NAG are to keep the handoff dropping probability below a target value, AG is to guarantee no handoff drops through per-connection bandwidth reservation, and BHARG and NCBF use ano...
