In this paper we present a probabilistic calculus for formally modeling and reasoning about Mobile Ad Hoc Networks (MANETs) with unreliable connections and mobility of nodes. In our calculus, a MANET node can locally broadcast messages to a group of nodes within its physical transmission range. The group probability is also introduced since two distinct nodes within different groups should receive...
Wireless sensor networking, as a burgeoning technology, supports the monitoring of physical environments and control of sensor data, and has been widely applied in many fields. Due to its unique features, a number of formal theories, as well as verification tools, have been developed to make an in-depth study. In this paper, we propose a timed broadcasting language, the Timed Wireless Sensor Processes,...
Several protocols have been proposed to defend against wormhole attacks in sensor networks by adopting cryptographic methods, packet leashes, directional antennas, or visualization, etc. In this paper, we propose a local energy-efficient method to detect wormhole attacks. This method can be applied in sensor networks with metric-based routing protocols and is independent of data aggregation. We define...
WSNs require cryptographic protection of communications between sensor nodes. Using bivariate polynomials, ID-based key management scheme given these functions, includes key distribution, key updating and sensor capture detection. Compromised nodes can recover by itself, by reducing memory requirement and less computation ability is needed. It is more suitable for sensor networks
Wireless sensor networks (WSNs) are wireless networks that include sensor nodes with limited storage and communication capabilities. Security in sensor networks is critical when there are potential adversaries. In this paper we propose a new key pre-distribution scheme which improves the resiliency and wisely uses the different network and the node resources. This scheme uses binary tree and matrix...
