Topology control is relevant in wireless sensor network because of two reasons, namely minimal sensor coverage and power constraints. The former condition is typically satisfied by high-density deployment, whereas the latter mainly concerns with the control protocol design that is adaptable. Controlling communication topology is at the center of the efforts to optimize network performance while improving...
Network connectivity maintenance in failure prone environment has received more attention in the recent years. Unfortunately due to hostile environment there is need of some other active nodes i.e. backbone nodes which can compensate the failure of the nodes. One of the main design challenges for wireless sensor network (WSNs) is to obtain connecting dominating set (CDS) in polynomial time with low...
In wireless sensor networks, it is already noted that nearby sensor nodes monitoring an environmental feature typically register similar values. This kind of data redundancy due to the spatial correlation between sensor observations inspires the research of in-network data aggregation. In this paper, an α -local spatial clustering algorithm for sensor networks is proposed. By measuring the spatial...
