Wireless sensor networks (WSNs) consist of lightweight devices with low cost, low power,
and short‐ranged wireless communication. The sensors can communicate with each other …

Wireless sensor networks are widely deployed and implicitly characterized by stringent
energy and computation constraints. Sensor nodes are vulnerable to false positive and false …

In this paper, we propose a symmetric key establishment scheme for wireless sensor
networks which tries to minimize the resource usage while satisfying the security …

With the advances of sensing, wireless communication, and mobile computing, mobile
crowdsourcing has become a new paradigm for data collection and retrieval that has …

The prevention of node capture attack is an important issue for wireless sensor network
(WSN) security. Key management plays a crucial role in providing secure communication …

We analyze the connectivity of a heterogeneous secure sensor network that uses key
predistribution to protect communications between sensors. For this network on a set V n of …

Heterogeneous wireless sensor networks (HWSNs) can achieve more tasks and prolong the
network lifetime. However, they are vulnerable to attacks from the environment or malicious …

Recent researches have witnessed that secret keying functionality is very important to
protect wireless sensor networks from existing adversary. Based on inherited nature and …

Security is one of the main challenges in Ad Hoc Mobile Networks (MANETs-Mobile Ad Hoc
Networks). The natural characteristics of MANETs make these networks highly vulnerable to …

In mobile wireless sensor networks, the process of offering security to the network after
computing dynamic key may result in misuse of information by malicious node. All the …
