Short message service (SMS) will play a very vital role in the future business areas whose are popularly known as m-commerce, mobile banking etc. For this future commerce, SMS could make a mobile device in a business tool as it has the availability and the effectiveness. The existing SMS is not free from the eavesdropping, but security is the main concern… (More)
In this paper, we propose multipath transmission mechanism from optical line terminal (OLT) in an optical wireless converged network architecture. In a scenario where the content server is far away from the terminal, in terms of distribution of traffic properly the proposed mechanism shows better performance than existing solutions.
In this paper, we consider both 1) an non-layered coding and 2) a layered coding based (i.e., scalable video coding based) multicast transmission. Specifically, the non-layered coding based multicast transmission guarantees fair services over all users in multicast group (MGroup), however it might require much power consumption to support the fair service… (More)
Recent IEEE and ITU-T standards for time division multiplexing-passive optical networks (TDM-PONs) with sleep mode recommend that the optical line terminal (OLT) in a TDM-PON should be in charge of invoking the optical network units (ONUs) to move into the sleep state in the absence of frames. It is considered that, upon upstream frame arrival, a sleeping… (More)
Sleep mode has been widely applied in TDM-Passive Optical Networks for maximizing energy saving. However, it can significantly influence QoS performance of traffic. In this article, we present an insightful study results which comprehend how delay variation performance of a flow can be influenced under different length of sleep intervals used in Optical… (More)
Passive Optical Networks (PONs) are assumed to be green access technology; however, there is still big room to maximize its energy saving. Therefore, there are significant research efforts in industries and academia. To evaluate and compare different types of energy efficiency solutions in PON, mathematical models are already studied energy efficiency.… (More)
This paper proposes a web based energy cloud platform framework for analyzing energy consumption behavior of campus environment, forecasting future energy demand and controlling some power hungry appliances when electricity demand overpasses generation. In addition to that, one of the key objectives of our work is to incorporate a rule based data filtering… (More)
As the number of requiring multimedia streaming and broadcasting such as IPTV through wireless access network, to provide efficient mobility in access network can be important issue. Proxy Mobile Internet Protocol (PMIP) is aimed for network side mobility support without Mobile Node side processing. In this paper, we extended our previous work by developing… (More)
In this paper, we discuss the issues that are needed to consider in proxy mobile IP (PMIP) deployment over Ethernet passive optical network (EPON) architecture. We present two architectures in this paper and discuss their strengths and weaknesses. Our discussion and analysis can help the network operators to deploy PMIP in EPON environment.
Energy saving paradigm is a global issue, and the access network consumes a significant portion of entire network-energy consumption. In the literature survey, we can find several research outcomes presenting several ground breaking solutions to minimize energy consumption in access networks (e.g. TDM-PONs). One promising energy saving technique is… (More)
