In addition to blog and schedule sharing, sharing physical data, such as noise or temperature values, and event data, such as information recorded when purchasing at a shop, with other nodes located in a distributed manner enables new applications using geographic distribution. Geographic distribution of physical data of noise allows a user to see geographic trends, such as the location of quiet areas,...
Most sensor nodes usually have the ability to vary their own wireless transmission power. Hence they have the potential to control the network topology, which is the pattern of links connecting pairs of nodes in a network. In this paper, we propose a connectivity ascertainment based distributed topology control algorithm. The algorithm draws out the potential from nodes for constructing an energy-efficient...
Wireless sensor network monitoring is important for network maintenance, since it keeps the observer aware of node failures, resource depletion etc. Since communication overheads increase if the sink collects data individually from all sensor nodes, in-network data aggregation methods have been proposed which reduce the overheads. They form a routing tree and data follows up from the edge of the tree...
