Future wireless applications will take advantage of rapidly deployable, self-configuring multihop ad hoc networks. Because of the difficulty of obtaining IEEE 802.11 feedback about link connectivity in real networks, many multihop ad hoc networks utilize hello messages to determine local connectivity. This paper uses an implementation of the Ad hoc On-demand Distance Vector (AODV) routing proto...

Nodes in mobile ad hoc networks communicate with one another via packet radios on wireless multihop links. Because of node mobility and power limitations, the network topology changes frequently. Routing protocols therefore play an important role in mobile multihop network communications. A recent trend in ad hoc network routing is the reactive on-demand philosophy where routes are established ...

In vehicular ad hoc networks data transfer is typically done with the help of multihop communication in which the high speed vehicles are acting as the data carrier. The vehicles are constrained to move on definite path depending on the road layout and the traffic conditions. In vehicular ad hoc network multihop data delivery is very complicated job because of the high mobility and frequent dis...

The TCP (Transmission Control Protocol) is a critical component in an ad hoc wireless network because of its pervasive usage in various important applications. However, TCP’s congestion control mechanism is notoriously ineffective in dealing with time-varying channel errors even for a single wireless link. Indeed, the adverse effects of the inefficient usage of wireless bandwidth due to the lar...

This work presents a Java-based development platform aimed to ease the task of building applications for mobile multihop ad-hoc networks. The platform follows a threetier development principle composed of simulation, emulation and deployment on real mobile devices. Opposed to pure network simulators, this development environment primarily focuses on an easy to use event-based programming model ...

Multihop ad hoc networking is a very appealing technology for the deployment of wireless data networks. It eliminates the need for network planning and the reliance on fixed infrastructure. Multihop ad hoc networks are designed with a self-configuring capability and are able to adapt to the addition or removal of network radio units (nodes). This capability makes them simple to install, allowin...

novel algorithm is presented to deduce individual nodal forwarding behavior from standard end-to-end acknowledgments. The based on a well-established mathematical method and robust network related errors changes. proposed solution was verified in simulation, during which it achieved sound results challenging multihop ad-hoc environment.

Ubiquitous and heterogeneous wireless network is an important form of network, and vertical handoff is one of the key issues of the mobility management in this type of network. In Ad hoc network, multihop-enabled forwarding is able to expand network coverage and reduce single-hop propagation distance. Based on the above, TMVHA (trusted and multihop-enabled Vertical Handoff Algorithms) is design...

A number of key agreement schemes based on wireless channel characteristics have been proposed recently. However, previous key agreement schemes require that two nodes which need to agree on a key are within the communication range of each other. Hence, they are not suitable for multihop wireless networks, in which nodes do not always have direct connections with each other. In this paper, we f...
