Mobile Ad hoc networks (MANETs) are composed of a collection of independent nodes usually connected by low bandwidth Radio Frequency (RF) links which are challenging for transmitting video and high bandwidth applications for rescue workers in emergency situations. Earlier we proposed a routing protocol, called AODVH to use for high bandwidth communication for search and rescue operations in a disaster...
Hybrid Free Space Optics (FSO)/Radio Frequency (RF) communication systems have emerged as a way to improve network performance by providing enhanced availability and reliability. In an effort to mitigate individual drawbacks in the optical link during adverse weather conditions, network traffic flows simultaneously between channels. Based on the Shannon-Hartley theorem, channel capacity is dependent,...
Ad hoc networks are characterized by nodes which are usually connected by low data rate Radio Frequency (RF) links when compared to optical links. RF links make it challenging for transmitting video and running high bandwidth applications over ad hoc networks. The objective of this paper is to develop a novel routing protocol for Ad hoc networks consisting of hybrid nodes using high bandwidth Free...
During natural or manmade disasters, communication infrastructures break down due to massive destruction and subsequent loss of services. Effective rescue operations require a rapidly deployable high bandwidth network to carry out necessary relief efforts involving helicopters up in the sky and first responders on the ground. However, transmitting video and running high bandwidth applications over...
To increase the availability of free space network (FSO) networks, the optical link is provided with a redundant backup network, such as RF, to form a hybrid network. The immediate switching from FSO to RF in hybrid networks leads to suboptimal utilization of FSO network. In this work, a network of hybrid nodes, where each node is equipped with multiple transceivers and has multiple associations with...
