Energy is a central concern in the deployment of wireless sensor networks. In this paper, we investigate the energy cost of cryptographic protocols, both from a communication and ...
Abstract-- The technological advances in Micro ElectroMechanical Systems (MEMS) and wireless communications have enabled the realization of wireless sensor networks (WSN) comprised...
— Clustering sensor nodes increases the scalability and energy efficiency of communications among them. In hostile environments, unexpected failures or attacks on cluster heads ...
Lifetime of a wireless sensor network is affected by key factors such as network architecture, network size, sensor node population model, data generation rate, initial battery bu...
In this work we present three new distributed, probabilistic data propagation protocols for Wireless Sensor Networks which aim at maximizing the network's operational life and...
