Blockage of communication links due to environmental obstructions and the resulting on/off channel behavior present challenges for providing reliable communication in mobile wireless networks. Traditional reliability techniques such as forward error correction and automatic repeat request (ARQ) are not designed to operate at the timescales typically observed in blockage channels. This work presents...
An ad hoc network is a collection of mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. Several routing protocols have been proposed for ad hoc networks and prominent among them are Ad hoc On Demand Distance Vector Routing (AODV) and Dynamic Source Routing (DSR). Effort has been made to merge software Quality assurance...
Wireless sensor network is used to monitor and record physical conditions of the environment or any other physical object and organizing the collected data at a central location called as base station. Sensor nodes in sensor network are spatially dispersed. In this paper a new protocol REBM (Residual energy based multipath routing protocol) has been created based on residual energies of nodes and...
Delay Tolerant Network (DTN) shows some features like link frequent interruptions, long delays, limited resources and so on, while nodes fight each other to win the network resources in the process of communication, which can lead to network congestion in delay tolerant network. Therefore, congestion control is a key issue in delay tolerant network research. The present congestion control strategies...
Distributed Data Mining (DDM) approaches are considered most suitable for managing large datasets. DDM can reduce the communication cost, computational cost, and storage cost. However a key issue for DDM is accuracy of knowledge discovery. To mitigate the accuracy issue, it is necessary to provide reliable network. In practice, it is assumed that the network is available all the time but in reality,...
The growth in wireless devices and multimedia applications has led to increase in spectrum usage in recent past. One of the credible solutions to overcome this shortcoming is by the usage of Cognitive Radios (CR). The Cognitive Radio has spectrum sensing capabilities and thus can improve spectrum usage. The ad hoc network employing CR are termed as Cognitive Radio Ad Hoc Networks (CRAHN). To establish...
Wireless sensor networks are spatially distributed network of autonomous nodes that are used in the monitoring of physical and environmental conditions. Since these sensors have limited energy to work with, their storage and processing capabilities are very much basic. They also have very limited transmission range. Recent approaches have seen immense investments using WSN that demands sensor networks...
As vehicular ad-hoc network (VANET) is a typical wireless mobile communication network and data packet routing in between various nodes is difficult task in an open network. As the various nodes are mobile and it located different places and to have communication in between nodes we used wireless channel. To have effective connection between nodes we used ad-hoc on demand multipath distance vector...
A wireless sensor network (WSN) usually operates in an unreliable wireless environment with energy constraint. Many researchers are primarily interested in energy awareness and communication reliability of WSNs to maximize network lifetime. However, dealing with the conflicting problems of improving energy efficiency and fault-tolerance simultaneously is a challenging task. Most previous studies have...
Reliability, Power efficiency and Delay are critical issues in Wireless Sensor Networks.

This framework aims to route the packets along multiple paths with the delay that is known earlier and with energy and link...
A wireless sensor network is a group of devices that uses radio to monitoring and sensing physical or environmental conditions at different location. Commonly monitored parameters are pressure, temperature, humidity, wind direction and speed, sound intensity, power-line voltage, and chemical concentrations. However, Energy efficiency is an essential design issue is a challenging task. In this simulation...

MAEE uses MMRE+AOMDV protocol to build the multiple paths and then score them using path conditions based on availability of resources. Simulation is performed using ns-2.27 platform and results evaluated in the simulation demonstrate a significant performance parameter improvement.
Low-Power and Lossy networks (LLNs) cover a wide scope of applications, including, but not limit to, industrial control, healthcare and building automation, which has proliferated into both industrial and academic areas in recent years.
