A channel allocation method for IEEE802.19.1 coexistence service to mitigate interferences among heterogeneous wireless networks

IEEE 802.19.1 is the world first standard that specifies coexistence methods by means of exchanging messages between 802.19.1 coexistence system and wireless systems registered to the coexistence system. We propose a channel allocation mechanism for 802.19.1 management service. The mechanism mainly depends upon channel classification where the CM manages channel availability information based on TV […]

Research on dynamic routing algorithm of the combat collaboration communication network

The military communication system is the key element to make a victory in the battle. In general, the combat collaborative communication network is a multi-hop and autonomous system, which is composed by a group of mobile nodes with wireless communication ability. The network has some features such as no center, self-organizing, multi-hop routing and dynamic […]

A new bandwidth-efficient multicast routing scheme for mobile Ad hoc Networks

This paper proposes an improved scheme based on Bandwidth-Efficient Multicast Routing (BEMR) for Mobile Ad Hoc Networks (MANET) to further reduce the control overhead whilst increasing the overall bandwidth efficiency. After carefully studying the original BEMR design, two new approaches are proposed to enhance the BEMR performance. One is in the tree set-up phase, while […]

Traffic Engineering Using Multi-protocol Label Switching (MPLS) for Delay Sensitive Traffic

Traffic engineering is one of the most challenging topics in Multi-protocol Label switching (MPLS) which deal with controlling traffic in such a way so that optimized path can be achieved with respect to network utilization and efficient data delivery. Internet traffic use Interior Gateway Protocol (IGP) to send traffic over the network using the shortest […]

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 […]

Efficient MAC protocols optimization for future high density WLANS

Recently, the High Efficiency WLAN or simply HEW study group was created within IEEE 802.11 working group. This study group considers the improvement of spectrum efficiency to enhance the system’s area throughput in high density scenarios. Subsequently, this led to the creation of a new task group called 802.11ax, which is expected to deliver the […]

Visualization of large wireless network behavior using random matrix theory

Recent works on the universality of Empirical Spectral Density (E.S.D) of Random Matrices have provided a framework to study the asymptotic behavior of random network data. In this paper, the behavior of a wireless campus network with low received base-station transmit power is investigated. Mobile users are organized into 10 clusters of 25 mobile users […]

Characterization of Wireless Mesh Network performance in an experimental test bed

Studies in Wireless Mesh Networks have often focused on the comparison of various mesh protocols, or the design of new mesh protocols in a simulation environment (such as NS2, OPNET etc.). However the results obtained in a simulation environment are sometimes not valid in a real site where the network is meant to be deployed. This paper […]

Cognitive Access Point to Handle Delay Sensitive Traffic in WLANs

Over the last few years, the widespread use of wireless local area networks (WLANs) continues to gain more and more impetus. Due to the increase in variety of multimedia applications such as voice, video and gaming traffic, it is paramount to develop a mechanism for the quality of service (QoS) to support different types of […]
