OFDMA-based multicast with multiple base stations

OFDMA-based multicast with multiple base stations

We consider an orthogonal frequency division multiple access (OFDMA)-based multicast system where multiple base stations transmit a multicast session to a multicast group. The goal is to maximize the multicast rate (i.e. the minimum achievable user rate) subject to a total power constraint. We assume the use of an erasure code (e.g., a Reed–Solomon code) or rateless code (e.g., Luby transform c...

Energy-Efficient and Fault-Tolerant Positioning of Multiple Base Stations

As the nodes have limited battery power in Wireless Sensor Networks (WSNs), energy efficiency and fault tolerance should be the two major issues in designing WSNs. However, previous studies on positioning base stations (BSs) in WSNs are focused on energy efficiency only. Yet, mission-critical applications like emergency medical care systems should be guaranteed continuous services considering f...

A Cellular Network Model with Ginibre Configurated Base Stations a Cellular Network Model with Ginibre Configurated Base Stations

Recently, stochastic geometry models for wireless communication networks have been attracting much attention. This is because the performance of such networks critically depends on the spatial configuration of wireless nodes and the irregularity of node configuration in a real network can be captured by a spatial point process. However, most analyses of such stochastic geometry models for wirel...

Context based configuration management of plug & play LTE base stations

In second and third generation cellular networks the rollout of base stations needs to be conscientiously prepared, because their radio configuration should match with the coverage provided by existing cells in their neighborhood. The detailed radio planning for every new cell requires considerable human resources and time. This paper proposes a framework for 3G Long Term Evolution (LTE) that c...
