In the view of the large scale and increasing kinds of service of space information networks, a service- oriented topology control algorithm is proposed. According to demands of existing service, the topology of network is divided into several logical sub-topologies, on which construct the corresponding topology. Taking the communication pattern as an example, the augmentation-based approach is adopted...
This work investigates a simple immune optimization algorithm in noisy environments for chance constrained programming problems without a priori noisy information. It bases on stochastic simulation and some immune metaphors in the clonal selection principle. The key of the algorithm is to design an adaptive sample allocation scheme and to construct the immune operators of dynamic proliferation and...
Congestion has always been a serious problem for all kinds of communication networks. Wireless sensor networks (WSN) face special difficulties in dealing with congestion due to their unique requirements and constraints. Various congestion control schemes for WSN have been proposed recently. These schemes try to solve the problem either at the MAC layer or through a cross-layer approach. This paper...
Molecular electronics such as silicon nanowires (NWs) and carbon nanotubes (CNTs) have emerged as the potential fabrics for building future nanocomputing systems. However, the non-ideal fabrication process and the consequent excessive defect rates make reliable molecular computing a challenging task. Existing solutions addressing this problem aim at achieving the absolute correctness, which becomes...
