In this paper, a distributed traffic-balancing routing protocol is proposed for multi-sink industrial wireless sensor networks that effectively distributes traffic from sources to sinks. Each node has a gradient field that is used to decide on a neighbor node to reach a sink. The node's gradient index contains (1) the distance cost from source to a respective sink, and (2) traffic information from...
Distributed medium access control protocols can be classified into contention-based and contention-free protocols. In this paper, we analyse a contention-free distributed protocol where nodes make reservations on a first-come first-served basis. We evaluate the impact of this first-come first-served approach on the fairness regarding throughput and delay, by means of the ECMA-368. This standard establishes...
A software-based time slots coordination mechanism (TSCM) for IEEE 802.11 WLANs is proposed in this letter to guarantee the quality of service (QoS) for voice traffic and avoid starvation for data traffic. With the complexity analysis, relative simplicity of TSCM is shown. Via simulations, we demonstrate that TSCM outperforms the enhanced distributed channel access (EDCA), hybrid coordination function...
As the Internet evolves, traffic management has become a high-priority problem. Without a network centric traffic management scheme, severe fairness problems can arise. For instance, unfairness occurs with TCP traffic in the presence of careless or subversive misbehaving flows, or even in the presence of other TCP flavors if we consider inter-protocol unfairness. In this paper we propose a new AQM...
OFDMA-based relay-enhanced cellular systems have been proposed as a promising solution for the next-generation wireless communications. The deployment of relay stations (RS) in cellular networks makes resource scheduling a more crucial and challenging task. In this paper, a novel centralized scheduling scheme called centralized scheduling with void filling (CS-VF) is proposed for two-hop relay-enhanced...
