متن کاملNeighbor discovery in wireless networks with sectored antennas
Directional antennas offer many potential advantages for wireless networks such as increased network capacity, extended transmission range and reduced energy consumption. Exploiting these advantages requires new protocols and mechanisms at various communication layers to intelligently control the directional antenna system. With directional antennas, many trivial mechanisms, such as neighbor di...
متن کاملThe Myth of Spatial Reuse with Directional Antennas in Indoor Wireless Networks
Interference among co-channel users is a fundamental problem in wireless networks, which prevents nearby links from operating concurrently. Directional antennas allow the radiation patterns of wireless transmitters to be shaped to form directed beams. Conventionally, such beams are assumed to improve the spatial reuse (i.e. concurrency) in indoor wireless networks. In this paper, we use experim...
متن کاملStochastic Geometry Based Framework for Coverage and Rate in Heterogeneous Networks with Sectored Fractional Frequency Reuse
Modern day cellular networks are driven by the need to provide ubiquitous connectivity with very high spectral efficiency to both indoor and outdoor users, hence the need to deploy small cells over conventional macrocells in a Heterogeneous Network (Hetnet) deployment. To alleviate the resulting inter-cell and cross-tier interference, effective intercell interference coordination (ICIC) schemes...
متن کاملOn K-node Survivable Power Efficient Topologies in Wireless Networks with Sectored Antennas
We consider the problem of survivable minimum power bidirectional topology optimization in wireless networks with sectored antennas. In this paper, we take an algebraic view of graph connectivity, which is defined as the second smallest eigenvalue of the laplacian matrix of a graph. We propose a (sub-optimal) centralized heuristic procedure for constructing power efficient K-node connected topo...
