Localization systems typically make use of redundant range or angle measurements from as many neighbours as possible to reduce location error. In dense networks this comes at the cost of excessive messages with limited improvement in location accuracy. This paper presents a scheduling scheme to limit node density to a set of active reference devices, which reduces message overhead and increases network...
Sleeping policies are widely used in many contexts to reduce energy consumption in sensor nodes, ad-hoc terminals or mobile cell phones. Although there is extensive literature on energy saving in sensor networks, little has been done with respect to comparing additional costs, such as packet drop probability and buffer occupancies of sleeping versus non-sleeping policies, especially for multiple classes...
In this paper analytical relationship between transmission range and the network connectivity is obtained as a function of number of nodes for CDMA based multihop cellular network (MCN). We show that for a network of n uniformly distributed nodes in a single cell of unit radius, the transmission range r should be sufficiently larger than radic(2 ln n/n-1) to achieve asymptotic full connectivity. The...
