An important goal of the design of WDM (wavelength division multiplexing) networks is to use less wavelengths to serve more communication needs. According to the wavelength conflict rule, we know that the number of wavelengths required in a WDM network is at least equal to the maximal number of channels over a fiber (called maximal link load) in the(More)
Online Social Networks (OSNs) have recently emerged as an effective medium for information sharing. Unfortunately, it has been frequently observed that malicious rumors being spread over an OSN are not controllable, and this is not desirable. This paper proposes a new problem, namely the γ - k rumor restriction problem, whose goal is, given a social(More)

In wireless sensor networks, Virtual Backbone (VB) construction based on connected dominating set is a competitive issue for routing efficiency and topology control. Transmission ranges of sensors are not always equivalent. A sensor networks is modeled as a directed graph while sensors have different transmission ranges. In this paper, we will try to find a(More)
