This paper addresses the (r, 1 + e)-approximate near neighbor problem ( or (r, 1 + e)-NN) that is defined as follows: given a set of n points in a d-dimensional space, a query point q and parameter 0 < d < 1, build a data structure that reports a point within distance (1 + e)r from q with probability 1 -- d, if there is a point in the data set within distance r from q. We present an algorithm...
Content-Centric Networking (CCN), a recent innovative architecture, has brought about a great number of challenges for researchers whose ambition is to design such network with highly advanced ability to respond quickly to increasing demands from users. This receiver-driven content paradigm creates a different perspective of network. In this paper, we propose a coupled multipath congestion control...
As the prevalence of producing devices equipped with multiple interfaces, the idea to enhance network resource usage by developing a multipath transmission control protocol has recently captured great attention from many researchers. Moreover, there is a considerable increase in user demand of transmitting data over high speed and/or long delay networks. Various algorithms have been proposed lately...
In recent years, wireless sensor network (WSN) achieved many accomplishments in theoretical studies and practical applications. However, WSNs are facing with many challenges, one of the biggest challenges that the energy source is limited and difficult to recharge. Clustering is the efficient technique used to extend the network lifetime through data aggregation. In this paper, we propose a new approach...
Along with poor processing and storage capacity, each sensor in wireless sensor network (WSN) is equipped with a limited energy resource and difficult to be replaced in most application environments. However, the designs for wireless sensor networks focus on not only energy-efficiency issues but also other problems such as fault tolerance, scalability, latency, and network topology. In this paper,...
