Distributed Signaling and Routing Protocols in iCAR (Integrated Cellular and Ad hoc Relaying System)

چکیده
One of the major challenges that wireless system carriers and infrastructure providers will face is to meet the increased bandwidth demand of mobile Internet users, and deal with the bursty and unbalanced IP traffic, which exacerbate the problem of limited capacity in cellular systems. The iCAR (integrated Cellular and Ad hoc Relaying) system was recently proposed to address the congestion problem due to the limited bandwidth in a cellular system and provide interoperability for heterogeneous networks. In this paper, we present the distributed signaling and routing protocols for establishing QoS (i.e. bandwidth) guaranteed connections for IP traffic in iCAR. In particular, we discuss how a relaying route between a MH (Mobile Host) and a BTS (Base Transceiver Station) in a nearby cell can be established via ARS’s (Ad hoc Relaying Stations), and evaluate the performance of the protocols in terms of request rejection rate and signaling overhead through simulations.

In this paper, we study the hand-off performance of a wireless system with heterogeneous technologies called iCAR (Integrated Cellular and Ad hoc Relaying). In iCAR, hand-offs can occur not only from a Base Transceiver Station (BTS) to another BTS, but also from a BTS to a so-called Ad hoc Relaying Station (ARS) in the form of relaying, as well as from an ARS back to a BTS. The latter two types...
متن کاملiCAR : an Integrated Cellular and Ad hoc Relaying System
The cellular concept was introduced for wireless communication to address the problem of having scarce frequency resource. It is based on the sub-division of geographical area to be covered by the network into a number of smaller areas called cells. Frequency reuse in the cells far away from each other increases system’s capacity. But at the same time, the cell boundaries prevent the channel re...
