Given a graph G = (V, E), a node is called perfect (with respect to a set S ⊆ V) if its closed neighborhood contains exactly one node in set S, a node is called nearly perfect if it is not perfect but is adjacent to a perfect node. S is called a perfect neighborhood set if each node is either perfect or nearly perfect. We present the first self-stabilizing algorithm for computing a perfect neighborhood...
Selection of Influential Users is an essential task in influence propagation schemes in social networks. Considering the phenomenon of asymmetric influences between neigh boring users and different sensitivities of users to influences, we propose to select the users in the minimal weighted positive influence dominating set of a social network graph as the influential users to maximize the speed of...
In a graph or a network G = (V, E), a set S ⊆ V is a 2-packing if ∀i ∊ V : |N[i]∩S| ≤ 1, where N[i] denotes the closed neighborhood of node i. A 2-packing is maximal if no proper superset of S is a 2-packing. This paper presents a safely converging self-stabilizing algorithm for maximal 2-packing problem. Under a synchronous daemon,...
Integrated Mobile Broadcast (IMB) is a technology recently standardized by 3GPP for delivery of broadcast multimedia via a cellular network. IMB is based on WCDMA technology but particularly designed for deployment in 3G TDD spectrum. It employs downlink-only channels using SFN methods, which greatly increase spectral efficiency and capacity for broadcast services. In this paper, we firstly provide...
IEC 61850 was proposed as a standard protocol for communications within the substation. In its current edition, the standard does not cover communications outside the substation, either with the control center or with other substations, for instance for remote protection. However, during the recent years, there has been a general belief that some features of the standard can be efficiently utilized...
Minimizing implementation time and manual configuration, as well as straightforward upgradability are the key requirements of efficient substation automation systems. For larger utilities this often necessitates achieving interoperability between different devices from multiple vendors. Since the early 1990's it was noticed that the speed of advances in communication technology seemed to overpass...
Alternating-Offer Protocol (AOP) is the most predominant way for one-to-one bargaining. Almost all past theoretical or practical researches on bargaining issue adopt AOP as the default trading rule. In this paper, we provide an alternative protocol, Sealed-Offer Synchronous Bargaining Protocol (SOSBP), which can be useful for the automated bargaining between self-interested agents for Open E-Marketplaces...
