“…Furthermore, in providing broad-band services over a wireless medium, smaller cells (micro-and picocells) are required to accommodate the overall increased system capacity. It is therefore expected that handoffs will occur more frequently than in the present cell environment [2], [3]. In addition, smaller cells will have tighter delay constraints, as the overlapping distance of cells becomes smaller.…”

With growing demand for higher bandwidth multimedia services in the wireless domain over the past few years, wireless asynchronous transfer mode (ATM) has emerged as a fine solution. Wireless ATM provides mobility support for mobile ATM users as they move among base stations. One of the key issues to support user mobility is the handoff. For a relatively smaller cell environment in wireless ATM, a handoff scheme should exhibit low handoff delay. Efficient usage of network resources is also required. In this paper, we propose a fast rerouting scheme for wireless ATM referred to as a path reservation scheme. For localized handoffs, we adopt a wireless cell clustering method. Cell grouping and a path reservation technique are proposed to achieve fast handoffs. This paper presents an analysis of the proposed scheme and simulation results of several handoff schemes compared with the proposed scheme. From the simulation results, our path reservation scheme achieves low handoff delay and efficient usage of network resources such as buffer and bandwidth requirements.
