Threshold behavior of multi-path random key pre-distribution for sparse wireless sensor networks

Threshold behavior of multi-path random key pre-distribution for sparse wireless sensor networks

Wireless sensor network (WSN) has been an active research topic because its application encompasses various domains. In particular, a lot of attentions have been paid to the common feature of WSN to show that every node in a large enough network contains certain properties. Real-world applications of random key pre-distribution naturally involve geometric and combinatorial techniques and are ev...

Random Key Pre-distribution Schemes using Multi-Path in Wireless Sensor Networks

Efficient ID-Based Threshold Random Key Pre-Distribution Scheme for Wireless Sensor Networks

Security for wireless sensor networks (WSNs) has become an increasingly serious concern due to the requirement level of applications and hostile deployment areas. To enable secure services, cryptographic keys must be agreed upon by communicating nodes. Unfortunately, due to resource constraints, the key agreement problem in wireless sensor networks has become quite complicated. To tackle this p...

LPKP: location-based probabilistic key pre-distribution scheme for large-scale wireless sensor networks using graph coloring

Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...

An efficient solution for management of pre-distribution in wireless sensor networks

A sensor node is composed of different parts including processing units, sensor, transmitter, receiver, and security unit. There are many nodes in a sensor unit. These networks can be used for military, industrial, medicine, environmental, house, and many other applications. These nodes may be established in the lands of enemies to monitor the relations. Hence, it is important to consider conse...
