Hybrid WLAN Markov Chain to Handle TCP and UDP Traffic

In the Modern Era of computing, The Wireless communication has gained popularity with the passage of time due to unique features, e.g. Flexibility, cost effective and easy to configure as compare to traditional wired networks. Since 1990swireless networks become the backbone of every network and there are lots of concerns in wireless communication, which are […]

Efficient scheduling of sporadic tasks for real-time wireless sensor networks

Industrial automation requires hard real-time delivery of data that can be of periodic or sporadic in nature. It is challenging to ensure hard real-time delivery of periodic and sporadic data to a multi-hop away destination in a bandwidth constrained environment, such as wireless sensor networks. In this regard, research has been done for joint scheduling […]

Link adaptation strategy for healthcare application on IEEE 802.15.4 WPANs

The signaling of the healthcare applications needs the error performance and the multiple data rate for different target rates of various bio-signals. In this paper, we propose a link adaptation strategy on the multi-rate modulation set for IEEE 802.15.4 wireless personal area networks (WPANs). The protocol stack made by the network simulator OPNET is used […]

Analytical model of multihop IEEE 802.15.4 for lossy medium

Wireless sensor networks (WSN) are used in many fields such as industrial control, building automation, environmental monitoring, etc. IEEE 802.15.4 standard defines the features of MAC layer and physical layer for WSN. Many analytical models studied the performance of the multihop IEEE 802.15.4 networks under the assumption of ideal wireless channel, and they did not […]

A new hybrid traffic generation model for Tactical Internet reliability test

Tactical Internet (TI) is the communication infrastructure of tactical level maneuver warfare forces; its reliability directly affects the military combat. Therefore, in the TI reliability test, how to generate the appropriate network traffic and get the most accurate evaluation results should be an important part of the TI reliability test research. This paper analyzes the […]

A Predictive Resource Allocation Algorithm in the LTE Uplink for Event Based M2M Applications

Some M2M applications such as event monitoring involve a group of devices in a vicinity that act in a co-ordinated manner. An LTE network can exploit the correlated traffic characteristics of such devices by proactively assigning resources to devices based upon the activity of neighboring devices in the same group. This can reduce latency compared […]

Modeling and Simulation of Data Flow for VLAN-Based Communication in Substations

IEC 61850, the standard for communication in substations, has resolved the interoperability between intelligent electronic devices (IEDs) from different vendors. Thus, the IEDs’ uniform communication standard contributes to the realization of more sophisticated functionality in substation automation systems. However, there are still several issues unsolved for the simulation, planning, and extension of substation communication network […]

Analysis of ISP caching in information-centric networks

Information-centric networking (ICN) models have recently emerged as novel network architectures for dealing with current Internet usage, where most users are interested in retrieving content without regard to its physical location. In this paper, we consider a noncooperative game between an Internet Service Provider (ISP) and content provider (CP) in an ICN model where the […]

WA-Method-TLV improves reliability of GMPLS WDM networks against multiple link failures

Concurrent multi-link failures in GMPLS Wavelength Division Multiplexing (WDM) networks can disrupt a large number of active optical circuits. These circuits need to be quickly restored in order to avoid prolonged traffic disruptions at the higher layers. The distributed nature of the GMPLS control plane requires that independent restoration attempts are conducted for each disrupted […]

ID-based communication for realizing IoT and M2M in future heterogeneous mobile networks

Internet of Things (IoT) and Machine to Machine (M2M) communication are expected to be the major paradigm of communications in the future Internet, where trillion of devices will be connected through heterogeneous mobile networks that will vary in both networking and link technologies. The IoT/M2M devices need to remain connected despite they change their points of […]
