In this paper, we discuss the ambiguity function (AF) synthesis problem for unimodular sequences, which are widely used in radar/sonar and communication systems. Notions of discrete-time ambiguity function and discrete ambiguity function (DAF) are defined, and the corresponding properties are also discussed for unimodular sequences. Depending on these properties, two algorithms are proposed to synthesize...
A Connected Dominating Set (CDS) is a subset V′ of V for the graph G(V, E) and induces a connected sub graph, such that each node in V - V′ is at least adjacent to one node in V′. CDSs have been proposed to formulate virtual backbones in wireless ad-hoc sensor networks to design routing protocols for alleviating the serious broadcast storms problem. It...
A Connected Dominating Set (CDS) performs a vital role in wireless ad-hoc sensor networks, which can establish a virtual backbone and thus leads to less maintenance overhead and information exchanges in wireless communications. In this paper, our algorithm first finds a prior CDS and then uses the Minimum-Weight Spanning Tree (MST) to optimize the result. Our algorithm applies effective degree, the...

A connected dominating set (CDS) performs a vital role in wireless ad-hoc sensor networks, which can establish virtual backbones and thus leads to less maintenance overhead and information exchanges in wireless communications. In the literature, many distributed algorithms applied in wireless ad-hoc sensor networks have been proposed. However, we find many of these algorithms are divided into different...
