In this paper, two formulations for planning base station (BS) and Relay Station (RS) locations are proposed: a rather complex 0-1 integer programming model which can be used to determine which set of locations should be selected from a given set of BS and RS locations and a simpler decomposition approach which focuses first on the BS location problem followed by the RS location determination. The...
The Stream Control Transmission Protocol (SCTP) is a transport layer protocol which can support mobility through its multi-homing feature. SCTP's mobility support can be subdivided into 2 areas: path performance evaluation and switch implementation. As a transport layer protocol, SCTP's path performance evaluation is limited by its end-to-end network view. In modern heterogeneous networks, it is likely...
Experimental results are presented for end-point controlled handover of a stream of voice-like packet data traffic between two independent wireless networks. The handover was achieved by using a version of the stream control transmission protocol (SCTP) that had been modified to monitor link quality and switch the primary connection to the ldquobestrdquo quality link available, where quality is evaluated...
In this paper, three approaches to modelling a distributed approach to interference mitigation in 802.16 license-exempt (LE) systems are described. An interference-free (IF) approach in which no interference is permitted at any node of the system; a controlled-interference (CI-T) and a controlled-interference with fairness (CI-F) approaches where interference is permitted at nodes that do not benefit...
