In this paper, we focus on the non-existence of isolated nodes in secure wireless sensor networks under full visibility condition. Here, we consider a sensor network with n sensor nodes distributed uniformly over a compact space $$C \subset {\mathbb {R}}^2$$ C ⊂ R 2 . We establish a threshold for the proportion of key ring and key pool size; above this threshold isolated nodes disappear...
In this paper, our work is to focus on the almost sure connectivity properties of secure wireless sensor networks. We consider a wireless sensor network which is generated randomly using random key pre distribution scheme given by Eschenauer and Gligor under non-full visibilitys. Here, we consider a sensor network in 2-dimensional space, and a sequence X„ = {Xi, X2,…Xn}, with n sensor nodes distributed...
In this paper we are considering a wireless sensor network with secure communication. k -connectivity is one of the most desirable features in a wireless sensor network (WSN). It allows messages to be routed through one (or more) of at least k disjoint paths. This ensure that if some nodes along one of the paths fail, or compromised, the other paths can still be used for sending data. We derive mathematical...
