node ad hoc network
Greek island gets wireless mesh network
News Mesh networking is an integral part of Negroponte's One Laptop Per Child project, with each $100 laptop acting as a wireless node to form a mobile ad hoc network (or Manet). The wireless Patmos network - due to launch this summer - has been jointly... [24 Jul 2008]
A Shoelace-Based QoS Routing Protocol for Mobile Ad Hoc Networks Using Directional Antenna
White Paper The QoS on-demand routing protocol determines the end-to-end bandwidth calculation and bandwidth allocation from a source node to a destination node. This paper proposes a new QoS routing protocol for Mobile Ad hoc NETwork (MANET) using directional... [18 Jul 2008]
QoS Topology Control in Ad Hoc Wireless Networks
White Paper Given a set of nodes in a plane, end-to-end traffic demands and delay bounds between node pairs, the problem is to find a network topology that can meet the QoS requirements and the maximum transmitting power of nodes is minimized. [18 Jul 2008]
Energy-Aware and QoS Routing in 6LoWPAN Mesh Networks
White Paper Almost all of the routing protocols considered energy efficiency as the ultimate objective since energy is a very scarce resource for sensor node. A routing protocol is needed for the mesh topology approach, which must take into account the very... [18 Jul 2008]
Performance Comparison of Ad-Hoc Routing Protocols for Networks With Node Energy Constraints
White Paper This paper compares the performance of ad-hoc routing protocols in a network where each participating mobile node has a given battery life and will shut-down when a threshold is reached. It studies two routing protocols, Dynamic Source Routing (DSR... [11 Jul 2008]
Energy Efficient Node Caching and Load Balancing Enhancement of Reactive Ad Hoc Routing Protocols
White Paper This paper suggests a novel approach to modify route request broadcast based on node caching. The intuition behind node caching is that the nodes involved in recent data packet forwarding have more reliable information about its neighbors and have... [10 Jul 2008]
Detecting Critical Nodes for MANET Intrusion Detection Systems
White Paper The common design goal of reactive, proactive, and hybrid ad hoc routing protocols is to faithfully route packets from a source node to a destination node while maintaining a satisfactory level of service in a resource-constrained environment. [31 May 2008]
TCP-BuS: Improving TCP Performance in Wireless Ad Hoc Networks
White Paper However, in wireless ad hoc networks, links are broken as a result of node mobility and hence some time is needed to perform route reconfiguration. Reliable data transmission over wireless multi-hop networks, called ad hoc networks, has proven to... [14 Jan 2008]
Performance Improvement of TCP Over an Ad Hoc Network by Combining of Data and ACK Packets
White Paper To reduce the likelihood of packet collisions when an intermediate node transmits both data and ACK packets, these two types of packet can be combined and transmitted at the same time to increase the efficiency of radio channel utilization. [14 Jan 2008]
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. To reduce the likelihood of packet collisions when an intermediate node transmits both data and ACK packets, these two types of... [14 Jan 2008]
Low Delay Marking for TCP in Wireless Ad Hoc Networks
White Paper This paper proposes LDM1, an IP layer queue marking mechanism that estimates the number of hops and flows at each wireless node to computes the optimal marking probability. End-hosts on wireless ad hoc networks typically use TCP as their transport... [14 Jan 2008]
Multipath TCP in Lossy Wireless Environment
White Paper Random loss in wireless ad hoc nets derives from two main causes: lossy wireless channels and node mobility. Breakage and loss can significantly degrade the performance of network protocols, especially TCP. [05 Dec 2007]
On TCP Performance in Multihop Wireless Networks
White Paper As long as the buffer size at each node is reasonable (larger than 10 packets), buffer overflow-induced packet loss is rare and packet drops due to link-layer contention dominate. This paper studies TCP performance over static, ad hoc networks that... [06 Nov 2007]
Kerberos Assisted Authentication in Mobile Ad-Hoc Networks
White Paper As the low transmission power of each node limits its communication range, the nodes must assist and trust each other in forwarding packets from one node to another. An ad-hoc network comprises mobile nodes that cooperate with each other using... [03 Sep 2007]
Establishing Trust in Pure Ad-Hoc Networks
White Paper Nodes assist each other by passing data and control packets from one node to another, often beyond the wireless range of the original sender. An ad-hoc network of wireless nodes is a temporarily formed network, created, operated and managed by the... [03 Sep 2007]
