Data collection using WSN for counting individuals and habitat characterization

Nathalie Dessart, Philippe Hunel, N. Dessart, P. Hunel

Journal of Computational Science > 2014 > 5 > 4 > 624-632

Decrease in the number of individuals of a species is an indicator of the state of biodiversity in a region. It is difficult to estimate this decline in the traditional way. We suggest to use ICT to measure this phenomenon. We propose using a distributed algorithm to count individuals in a population and to collect abiotic factors in order to characterize habitat. The first phase consists of detecting...

S. Murugaveni, B. Priyalakshmi

Concurrency and Computation: Practice and Experience > 35 > 22 > n/a - n/a

Wireless sensor network (WSN) is an environmental monitoring system exposing sensor nodes to various attacks. Jamming is an attack that disrupts the entire sensor network and affects the network's life span. The jammer broadcasts the signal at a frequency similar to the broadcast signal to jam the corresponding sensor node. There are many jamming detection schemes that only detect the jamming node,...

Networks > 81 > 4 > 499 - 513

Given a wireless sensor network, we consider the problem to minimize its total energy consumption over consecutive time slots with respect to communication activities. Nonempty and disjoint subsets of nodes are required to be active and connected under a tree topology configuration in the different time slots, and each network node must be active in a unique time slot. Moreover, the power required...
