Opportunistic channel reuse for a self-organized visible light communication personal area network

We investigate the adverse effect of interference in a visible light communication personal area network (VPAN) installed inside a museum. A VPAN should support diverse traffic in commercialized deployment. However, the state-of-the-art VPAN suffers from interference while supporting diverse and multidimensional traffic. The key challenge remains to satisfy and manage diverse quality of service (QoS) requirements of various applications while keeping the interference under the threshold level. Therefore we proposed interference bounded opportunistic channel allocation strategies for visible light communication personal area network (VPAN) in a cost effective manner which intends to maximize the sum rate capacity in the downlink channel and thereby allow maximum number of users within a target QoS. Performance analyses show improvement in terms of outage probability and throughput maximization.
