Abstract

Large-scale wireless sensor and actuator networks(LWSANs) are networks that consist of many sensor and/or actuator devices (i.e. >1,000 devices). These sensor and/or actuator devices (also called nodes) communicate wirelessly to deliver their sensor readings to one or more gateway devices in the network or to receive information from other parts of the networks to carry out actuation tasks or receive configuration information.

This invention describes the organization of wireless communication for large-scale monitoring and actuation applications. Typically, these networks must be designed to use efficiently available bandwidth in the wireless communication channel and to be able to deal with high node densities. Envisioned deployments of such networks consist of several square kilometers of terrestrial surface with nodes every few square meters. This enormous deployment area, the high sensor density and the (potential) large data volume that must be transported (potentially near real-time) make an interesting challenge. This invention describes methodology to organize communication in LWSANs. Topics like spatial time slot and frequency allocation and medium access control protocols are discussed.

The present invention relates to a communication method for high density wireless networks. The present invention also relates to a terminal for use in a high density wireless network. The present invention further relates to a cluster master device for use in a high density wireless network. The present invention also relates to a central node for use in a high density wireless network. Furthermore, the present invention relates to a system for use in a high density wireless network.
