Using forward error correction (FEC) in off-line streaming, permitting large buffers, yields spectacular results, but real-time streaming puts hard restrictions on the buffer size and therefore does not allow FEC to deal with long link failures on a single path route. Multi-path routing however can make FEC efficient also for realtime streaming. In this paper, we introduce a capillary routing algorithm...
This paper investigates and undertakes simulation-based comparison of on-demand routing protocols in multi ad hoc networks. First, it investigates the factors affecting the performance criteria and working architecture of ad hoc on-demand distance vector (AODV) and optimized link state routing protocol (OLSR). Second, it considers proposing a scenario of multi ad hoc network domains and their inter-communication...
Multi-hop wireless ad hoc networks have the potential to dramatically reduce the cost of deploying communication infrastructure. However, the nature of this technology limits the capacity of radio links. Thus, it is important to utilize them as efficiently as possible. Routing in ad hoc sensor networks is a complicated task because of many reasons. For traffic engineering, multipath capabilities are...
The ad hoc on-demand distance vector (AODV) routing protocol, designed for mobile ad hoc networks, has two main objectives. First, it enables route establishment between a source and a destination node by initiating a route discovery process. Second, it maintains the active routes, which means finding alternative routes in a case of a link failure and deleting routes when they are no longer desired...
This article describes the new approach to dynamic recourse allocation and routing protocols in the high speed wireless UWB ad hoc networks based on hybrid switching technology. The specified network is PAN oriented (personal area network) and can be used for cable replacement purposes. Unlike the majority of the existing ad hoc wireless networks, which have a tendency to use the trace packets based...
The cross-layer design approach is an important concept in mobile ad-hoc networks which is adopted to solve several open issues. It aims to overcome MANET performance problems by allowing protocols belonging to different layers to cooperate and share network status information while still maintaining separated layers. While cross-layer model could enhance the performance of the applications and achieve...
Ad hoc networks interconnect mobile terminals without intervention of a base station, in other words these networks do not use traditional infrastructure of base stations to interconnect to complete a communication link. In these networks, the mobile units operate in store and forward mode until the data reaches the destination. Due to mobility of the participating nodes, the network configuration...
Today, vehicles are widespread and traffic is increasing. Therefore road safety is a major problem. To solve traffic problems, special attention is given to develop systems that can reduce the number and severity of road events. Additionally, the spread of wireless communication and mobile devices creates self-organizing networks, which are ad-hoc, that do not require a pre-established infrastructure...
Wireless ad hoc sensor networks are widely deployed due to their various applications. Some of these transmitter sensors comprising of cameras, scanners, etc., usually send halftoned images to the receiver in the communication link to reduce the amount of transmitted data and power consumption. In these wireless networks the transmitted data is usually turbo coded as turbo codes have been found to...
