Due to major differences with respect to its counterpart in infrastructure networks, the handoff problem in ad hoc networks needs to be treated through an integrated multi-layer approach. In this paper, an integrated framework through cross layer approach is presented to deal with the handoff problem in heterogeneous wireless networks with multiple interfaces. Further, extensive study has been conducted...
IEEE 802.16j multi-hop relay task standard includes two mutually exclusive options: transparent relay stations (T-RS) and non-transparent relay stations (NT-RS). In this work, a system design approach is proposed to compare different relay systems in term of their capacity with rate fairness constraint among the mobile stations (MS). Single-input single-output (SISO) and multi-input multi-output (MIMO)...
IEEE 802.16j multi-hop relay task standard defines two mutually exclusive options: transparent relay systems (T-RS) and non-transparent relay systems (NT-RS). In this work, we compare the two relay systems in term of system capacity under user resource fairness constraint. We jointly study the effect of resource allocation and user association rule for maximizing the system capacity, where the user...
IEEE 802.16j multi-hop relay task standard draft 16JD1 includes different options for relay stations. These options include transparent relay frame structure, non-transparent relay frame structure with scheduling function located in the base station (centralized scheduling) or in the relay station (distributed scheduling). These options are mutually exclusive, and it is important to understand the...
