The Minimum Number of Sensors – Interpolation of Spatial Temperature Profiles in Chilled Transportse average prediction error for intermediate points was estimated as a function of the number of sensors. The Kriging method, originally developed for the interpolation of geostatistical data, produced the best results.

Solving the Wake-Up Scattering Problem Optimallyerive the solution, based on integer programming techniques, allows for a particularly efficient solution. The latter result discloses important opportunities for the practical utilization of the model. The model is also general enough to encompass alternative formulations of the problem.

Area Throughput of an IEEE 802.15.4 Based Wireless Sensor Networksors and sinks are assumed to be Poisson distributed in a given finite domain. Sinks send periodic and synchronous queries, and each sensor transmits its sample to a sink, selected among those that are audible. The IEEE 802.15.4 Multiple Access Control (MAC) protocol is used by sensors to access the

QoS Management for Wireless Sensor Networks with a Mobile Sinkt optimise certain task-level QoS metrics. An existing configuration method is available for tree-based static networks. We extend this method to support a mobile sink. First, the routing tree is adapted to the sink’s new location, after which the parameters of the nodes are optimised. Both algorith

A Context and Content-Based Routing Protocol for Mobile Sensor Networksios, like those including actuators, involve .. Mobility and multiple sinks radically changes the way routing is performed, while the peculiarities of WSNs make it difficult to reuse protocols designed for other types of mobile networks..In this paper, we describe CCBR, a . protocol explicitly desig
