How to design an energy efficient routing algorithm is a hot topic in the research of wireless sensor networks. In this paper, based on the analysis of some typical cluster-based routing algorithms, a novel cluster-based energy efficient routing algorithm is proposed to solve the hot spot problem involved in inter-cluster routing and optimize network lifetime. Clusters are formed by local competition...
This paper applied the Methods which based on GEP in compress multi-streams. The contributions of this paper include: 1) giving an introduction to data function finding based on GEP(DFF-GEP), defining the main conception of Multi-Streams, and revealing the map relation in it; 2) putting forward the Compression Algorithm for Multi-Streams according to map relation lied in data between data streams;...
Traditional GEP algorithm takes up many system resources in decoding and evaluating due to the operation of the tree construction and corresponding traversing. This paper aims to introduce a novel GEP algorithm to alleviate the drawback mentioned above. The main contributions include:(1) presenting a new method for decoding and evaluating chromosome (SGDE), and proposing the corresponding ETs construction...
With advances in semiconductor process technology, chip power density has dramatically increased, making power grid integrity a critical concern at all stages of the design process. Given the inherent difficulty of capturing worst-case IR drops for all logic gates with dynamic vectors, a static flow is essential for verifying grid integrity on complex chip designs, especially microprocessors. A novel...
