In future tactical networks, gateway nodes will have an important role in connecting different military communications platforms together to form a consolidated network. To increase capacity for upstream/downstream traffic as well as resiliency, more than one gateway should be deployed. In this context, performing gateway load balancing is vital in order to take full advantage of the resources available...
IEEE 802.11-based mesh networks can yield a throughput distribution among nodes that is spatially biased, with traffic originating from nodes that directly communicate with the gateway obtaining higher throughput than all other upstream traffic. In particular, if single-hop nodes fully utilize the gateway's resources, all other nodes communicating with the same gateway will attain very little (if...
Wireless mesh networks (WMNs) have emerged as a promising and cost-effective approach to extending the coverage range of wireless local area networks (WLANs) and providing last-mile broadband Internet access. Mesh routers and mesh clients are the key components of WMNs. Mesh routers perform the dual tasks of forwarding packets as well as providing network access to mesh clients. Mesh routers facilitated...
In a wireless mesh network, the traffic is aggregated at mesh router and most of them forwarded towards the Internet through GW (Internet gateway). Thus easily leads to a bottleneck for network performance at GW. Aimed to this problem ,we firstly treated the GW and mesh router as the alike node equivalently. Then used the logarithm-normal distribution model of shadow affect in wireless communication...
Wireless Mesh Networks (WMNs) provide a cost-effective way of deploying a network and providing broadband Internet access. In WMNs a subset of nodes called gateways provide connectivity to the wired infrastructure (typically the Internet). Because traffic volume of WMNs is expected to be high, and due to limited wireless link capacity, gateways are likely to become a potential bottleneck. In this...
In wireless mesh networks (WMNs), the achievable throughput of a mesh client to a gateway (GW) is limited by the minimum link capacity of the intermediate nodes. In instances when the intermediate nodes experience congestion due to large relay traffic, link failure etc., this throughput may drop below an acceptable level. Since the mesh topology implies multi-path routing capability, it is possible...
Wireless mesh networks will play an important role in the next-generation wireless communication systems as it can provide wide coverage and scalable broadband Internet access services. However, congestion in such networks may lead to throughput degradation, packet loss and longer transmission delay. Therefore, routing and traffic forwarding schemes which are aware of the congestion status of a wireless...
In order to reduce the increasing packet loss rates caused by an exponential increase in network traffic, the Internet engineering task force is considering the deployment of active queue management techniques such as RED (random early detection). While active queue management in routers and gateways can potentially reduce packet loss rates in the Internet, this paper has demonstrated the inherent...
This paper is devoted to modeling and analysis of media gateway nodes for the next generation networks based on Markov reward models. The bandwidth sharing policy with partial overlapped transmission link is considered. Calls arriving to the link that belong to VBR and ABR traffic classes, are presented as independent Poisson processes and Markov processes with constant intensity or random input stream,...
