The last few years, users want various services that fit their needs and preferences. Many services are provided at network edges and are increasing in number. The open framework i...
Setting up an IDS architecture on ad-hoc network is hard because it is not easy to find suitable locations to setup IDS's. One way is to divide the network into a set of clust...
The explosive growth of new multimedia services over the Internet necessitates efficient network management. Improved network management systems are expected to simultaneously prov...
In this paper, we propose two mechanisms, differentiation by backoff exponent and differentiation by the size of contention window, for IEEE 802.15.4 sensor networks to provide mul...
Abstract. Despite the importance of seamless connectivity in ubiquitous computing, research for seamless connectivity has not been considered properly. To provide seamless connecti...
In this paper, we realize a DiffServ-based Multicast Router (DSMRouter) to provide the QoS adjustment for multicasting video transmission in the DiffServ network. To reach the QoS ...
Abstract. In this paper, an efficient neighbor AR (Access Router) discovery scheme and handoff procedure using neighbor information are proposed. It allows each AR and Mobility Anc...
Specifically ubiquitous computing paradigm is based on seamless connectivity. And also to guarantee the seamless connectivity, an intelligent network management between heterogeneo...
In this paper, we propose the localized adaptive QoS routing scheme using POMDP(partially observable Markov Decision Processes) and Exploration Bonus. In order to deal with POMDP p...
