Gigabit per second and higher bandwidths imply greater challenge to perform lossless packet capturing on generic PC architectures. This is because of software based capture solutions, which did not improve as fast as network bandwidth and they still heavily rely on the OS's packet processing mechanism. There are hardware and operating system factors that primarily affect capture performance. Th...

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...

Massively multiplayer online games (MMOGs) have gained enormous popularity amongst the game communities, industries and academic researches. In particular, first person shooter (FPS) and massively multiplayer online role-playing game (MMORPG) genres are most famed. FPS traffic is very delay sensitive like voice and its interactivity is similar to the multimedia. However, MMORPG traffic is less ...

We investigate the possibility of reducing router power consumption through dynamic router performance control. The proposed algorithm employs a typical low pass filter and, therefore, is simple enough to implement in each related element in a router. Numerical experiments using several real Internet traffic data sets show the degree of reduction in power consumption that can be achieved by usi...

Given the emergence of pervasive computing, Wireless Body Area Networks (WBANs) will play an increasingly important role in future critical system like Healthcare. Wireless Body Area Networks are consists of many inexpensive sensor nodes with limited energy and computational resources and memory. In this paper, a survey of existing projects is done to identify all the issues related to the heal...

Analytical and empirical studies have shown that self-similar trafic can have detrimental impact on network performance including amplified queuing delay and packet loss ratio. On the flip side, the ubiquity of scale-invariant burstiness observed across diverse networking contexts can be exploited to better design resource control algorithms. In this paper, we explore the issue of exploiting tr...

An important aspect of traffic engineering is the re-optimization of network resources. In this process, traffic over a congested path is rerouted to a new path to improve efficiency in network resource utilization. The aggregation nature of DiffServ MPLS networks often gives rise to long-lived flows within the network. A rerouting mechanism that supports the tearing-down of old connections and...

The use of wireless networks has become very popular in the mobile robotics community as they offer many advantages over traditional tethered systems. Wireless networks, however, often suffer from lower throughput and higher packet loss than their wired counterparts. This work attempts to enhance wireless networks used in mobile robotics by determining the optimal packet size for maximum throug...

Introduction: Studies of packetization schemes for the H.263+ video codec, for example [1], tend to assume the one slice per packet recommendation contained in RFC 2429 section 3.2 [2], whereas in this letter a two-slice scheme is proposed. In [3], the burst length is identified (for H.264) as a source of peak signal-to-noise ratio (PSNR) degradation, as much as the average packet loss rate. In...

This paper evaluates the performance evaluation of interaction between Transport and the MAC layer protocols operating in a mobile adhoc network. In Adhoc networks, certain QoS parameters like error rate, delay and packet loss are increased and certain parameters like throughput and delivery ratio are decreased in Transport layer is due to MAC problems and disconnection is also possible due to ...
