Due to a wider range of services in future heterogeneous cellular network (HCN), packet transmission delay becomes a more essential performance metric for system design. In this paper, we propose an analytical framework to derive the delay performance of HCN in terms of local delay, by modeling the locations of base stations (BSs) in HCN as superimposed of independent Poisson point processes. In the...
In two-tier heterogeneous cellular networks (HCN) where small cells are deployed overlaid with macro cells, base station (BS) association is one of the fundamental problems, which becomes even more challenging when the small cell BSs are connected to the gateways via imperfect backhaul links, e.g. using wireless technologies. In this paper, we first analyze the mean packet delay in radio access and...
