Wireless network coding has the potential to enhance the capacity of wireless mesh networks (WMNs). However, most of the work considering the practical deployment of network coding in WMNs considers only IEEE 802.11 based medium access control (MAC) layers. The recent emergence of sophisticated MAC standards supporting WMNs (e.g. IEEE 802.16) make it necessary to view the deployment issues for network...
Significant progress has been made in understanding the behavior of TCP and congestion-controlled traffic over multi- hop wireless networks. Despite these advances, however, no prior work identified severe throughput imbalances in the basic scenario of mesh networks, in which one-hop flows contend with two-hop flows for gateway access. In this paper, we demonstrate via real network measurements, test-bed...
The paper presents analysis of implementation of different MAC protocols in broadband powerline (BPL) networks. Analysis is focussed on impact of choice of MAC protocols on QoS parameters, specifically delay, packet loss rate and throughput. Subject of the paper is analysed on a test model of access (low-voltage) PLC cell, with BPL network customers generating different types of services (triple play...
The IEEE 802.15.4 protocol has the ability to support time-sensitive wireless sensor network (WSN) applications due to the guaranteed time slot (GTS) medium access control mechanism. Recently, several analytical and simulation models of the IEEE 802.15.4 protocol have been proposed. Nevertheless, currently available simulation models for this protocol are both inaccurate and incomplete, and in particular...
