Training a Wireless Sensor Network

Protecting the Communication Structure in Sensor Networks

“…The network model used in this paper is a derivative of the model introduced in [46,67]. Specifically, we assume a class of wireless sensor networks consisting of a large number of sensors nodes randomly deployed in the environment of interest.…”

“…Corona radii can be determined based on several criteria, e.g. in [46,67] they are designed to maximize the efficiency of sensors-to-sink multihop communication. The intersection of every wedge and corona defines a unique sector; each sector is uniquely identifiable by the combination of its unique wedge identifier, and unique corona identifier.…”

“…The intersection of every wedge and corona defines a unique sector; each sector is uniquely identifiable by the combination of its unique wedge identifier, and unique corona identifier. The training process guarantees that each node belongs to one and only one sector in the coordinate system, and that each node knows the identity of its sector [46,67]. Let c, and w be, respectively, the set of coronas, and the set of wedges defined by the training process.…”

“…We propose a transaction-based model for managing the computation and reporting of target process states. The model is a specialization of a transaction-based management model for sensor networks introduced in [46,67]. In this model, intra-cluster activity proceeds as follows.…”

“…ii.2. Corona train: using the sink side of the training protocol described in [67] do corona training to establish coronas for O s , such that iii.3.Wedge train: using the analogous sink side of the wedge training protocol described in [67], do wedge training to establish the wedges for O s . (ii) Terminate the protocol Note that the corona training done in step i.2 covers an area considerably larger than the network area.…”
