Improvement of TCP Throughput by Combination of Data and ACK Packets in Ad Hoc Networks
White Paper It is possible to transmit to two or more nodes which adjoin from a certain node simultaneously on the radio channel. Since a radio channel is shared among terminals in an ad hoc network, packet collisions are frequent. [14 Jan 2008]
Analysis of TCP Performance on Ad Hoc Networks Using Preemptive Maintenance Routing
White Paper In mobile Ad hoc networks, the topology of the network is constantly changing as nodes move in and out of each others range, breaking and establishing links. TCP performs poorly in such networks because packets that are lost due to path... [14 Jan 2008]
Estimating the Ad Hoc Horizon for TCP Over IEEE 802.11 Networks
White Paper This horizon is defined in terms of number of nodes and number of hops beyond which TCP based network services are not useful anymore. The paper shows that with IEEE 802.11 this horizon is as narrow as 2 to 3 hops and approximately 15 nodes. [14 Jan 2008]
Improving Fairness Among TCP Flows Crossing Wireless Ad Hoc and Wired Networks
White Paper In scenarios where wireless ad hoc networks are deployed, sometimes it would be desirable that ad hoc nodes can communicate with servers in wired networks to upload or download data. In these cases TCP connections will span both wireless ad hoc and... [08 Jan 2008]
Balancing Throughput and Fairness for TCP Flows in Multihop Ad-Hoc Networks
White Paper This paper focuses on the interactions between the hidden nodes and network congestion1. Analyzing transport layer operation and enhancing its performance over multihop ad hoc networks have attracted a lot of attentions. [08 Jan 2008]
Empirical Upper Bound on TCP Transmission Rate for Guaranteed Capture-Free Communications in Multi-Hop IEEE 802.11 Based Wireless Networks
White Paper It assumes that all nodes of competing TCP flows are located outside the assured reception range of each other but within the physical carrier sensing range. This paper considers the well known problem of TCP capture in mobile ad hoc networks... [26 Dec 2007]
Interaction Between TCP and UDP Flows in Wireless Multi-Hop Ad Hoc Networks
White Paper The interaction between TCP and UDP flows are examined experimentally in simple scenarios, involving between three and four nodes. This paper examines the interaction between TCP and UDP flows in wireless multi-hop ad hoc networks. [26 Dec 2007]
TCP Over Geo-Routing for High Mobility: Vehicle Grids and Airborne Swarms
White Paper A major challenge is the reliable delivery of data when nodes move. To this effect, Geo-routing has recently received attention in large scale, mobile systems as it does not require end-to-end path establishment and pre-computed packet forwarding... [05 Dec 2007]
An Edge-Based Approach for Improving TCP in Wireless Mobile Ad Hoc Networks
White Paper The base of this approach is to involve only the end nodes in the congestion control performed by TCP. In other words, no specific cooperation from intermediate nodes is needed. The Transmission Control Protocol (TCP) experiences severe performance... [05 Dec 2007]
TCP Performance Over Geo-Routing for High Mobile Ad Hoc Networks
White Paper Geo-routing is a routing approach which has recently received attention in large scale, mobile systems as it does not require end-to-end path establishment and pre-computed packet forwarding routing structure at nodes. [05 Dec 2007]
TCP Unfairness in Ad Hoc Wireless Networks and a Neighborhood RED Solution
White Paper If a node is viewed and its interfering nodes to form a "Neighborhood", the aggregate of local queues at these nodes represents the distributed queue for this neighborhood. This paper shows that the RED scheme does not work when running on... [04 Dec 2007]
TCP Performance With Active Dynamic Source Routing for Ad Hoc Networks
White Paper With collected source routes, mobile nodes are able to update their stale routes before TCP packets attempt to use them, thus reducing unnecessary retransmissions. With queue-length information, ADSR identifies potential congested nodes and... [29 Oct 2007]
The Capacity of Multi-Hop Wireless Networks With TCP Regulated Traffic
White Paper Specifically, this paper examines the sensitivity of the capacity to the speed of the nodes and the number of TCP connections in an ad hoc network. The paper studies the dependence of the capacity on the transmission range of nodes in the network. [02 Mar 2005]
