Flow control enhancements in Content Centric Networking

In window-based flow control mechanism for Content Centric Networking (CCN), for one Interest (a content request packet), more than one Content Objects (content chunks) are expected to be received. TCP’s RTT estimation algorithm cannot be used directly for such scenarios because for some contents, there will be no Interest reference. In this paper, we extend TCP’s RTT estimation for […]

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 […]

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 […]

Software defined and virtualized wireless access in future wireless networks: scenarios and standards

Future wireless networks are expected to provide augmented and data-intensive services in a multi-vendor multi-proprietor scenario. This scenario introduces relevant challenges to the networking infrastructure, especially in terms of flexibility and interoperability, that could be addressed by extending the concept of Virtualization and Software Defined Networking (SDN) to the wireless or wired-cum-wireless world. This paper provides a review of […]
