This paper proposes a conceptual framework for mobile learning applications that provides
systematic support for mobile learning experience design. It is based on a combination of a …

Wireless sensor networks (WSNs) may be deployed in failure-prone environments, and
WSNs nodes easily fail due to unreliable wireless connections, malicious attacks and …

Random intersection graphs have received much attention recently and been used in a wide
range of applications ranging from key predistribution in wireless sensor networks to …

We introduce a new random key predistribution scheme for securing heterogeneous
wireless sensor networks. Each of the n sensors in the network is classified into r classes …

Determination of source-destination connectivity in networks has long been a fundamental
problem, where most existing works are based on deterministic graphs that overlook the …

Security is an important issue in wireless sensor networks (WSNs), which are often deployed
in hostile environments. The q-composite key predistribution scheme has been recognized …

Challenges of authentication in decentralized mobile networks arise from frequently
changing topologies and unreliable contention-based transmissions. We propose a new …

We study the secure and reliable connectivity of wireless sensor networks. Security is
assumed to be ensured by the random pairwise key predistribution scheme of Chan, Perrig …

Wireless sensor networks (WSNs) are distributed collections of sensors with limited
capabilities for computations and wireless communications. It is envisioned that such …

We investigate k-connectivity in secure wireless sensor networks under the random pairwise
key predistribution scheme with unreliable links. When wireless communication links are …
