Minimizing the sensing activity during the pre-attack phase while meeting the performance requirements is critical for reducing the operational costs of chemical sensor networks. In this paper, we present a formal problem formulation for this optimization problem, and propose a decentralized, dynamic sensor activation protocol for meeting this goal. We analyze the behavior of the activation protocol...
Based on the previous work carried out on experimental validation of theory on fundamental bounds in communication network by J Y Le Boudec and Patrick Thiran in the context of networked control systems, steps are taken to define an algorithm enabling to automatically associate a time constraint requirement with a priority level and a weighted value. More advanced optimization algorithms are also...
This paper presents computationally efficient channel models, considered specifically from the point-of-view of network-level simulations. We outline models applicable at various system protocol layers of wireless communication systems, which take into account small-scale fading channel environments, and the time-variant error behavior relevant for mobile receivers. The presented models can be utilized...
In this paper, there is a need for a temporal analysis to evaluate and optimize a design with respect to the deadlines. The authors put forward some performance parameters of CAN bus and attempt to find better ways to simulate and evaluate its performance. The paper compares and analyzes the characteristics of CAN scheduling and that of RM. Finally, we present a Petri Net model with extended PNK2e...
A number of prefix delegation-based schemes have been proposed in the literature to solve the route optimization problem in mobile networks. The route optimization solutions generate overheads and affect the performance of mobile networks. However, currently there is no tool available to aid in the selection of an appropriate scheme for a given mobility scenario. The objective of this paper is to...
In this paper, we propose a cross-layer optimization approach that exploits retransmission diversity in wireless CDMA communications. Conventionally, data packets that are not correctly detected are usually dropped. These dropped packets can be used to help data packet detection. By exploiting all the retransmitted packets, data packets can be correctly detected with higher probability. The proposed...
