Performance Investigation of Reactive AODV and Hybrid GRP Routing Protocols under Influence of IEEE 802.11n MANET
In modern technology era, the endeavor of MANET is to provide proficient wireless communication by adopting adhoc routing functionality in mobile nodes. The MANET nodes result in frequent network topology changes, making routing a challenging task. In past, Reactive routing approaches are used as a popular technique that provides scalable solution to relatively large MANET […]
Making use of TMM of OPNET simulation tools and integrating the operational environment and mission scenario with the DSR routing algorithm of the mobile Ad Hoc network, this article presents a more realistic model of the tactical internet battlefield environment. It offers a good simulation environment for the tactical internet and information warfare.
Routing of data packets is one of the important process in the internet. A routing protocol specifies the method of communication among routers used in the inter connection of networks. There are number of routing protocols which have application on the internet like OSPF, RIP, EIGRP, OPNET, IGRP, etc. Every protocol has its own feature of […]
Linear sensor networks (LSNs) have recently attracted increasing attention due to the vast requirements on the monitoring and surveillance of a structure or area with a linear topology. However, there is little work on the network modeling and analysis based on a duty-cycling MAC protocol for LSNs. In this paper, we model a duty-cycling MAC […]
Performance evaluation of MPLS-enabled communications infrastructure for wide area monitoring systems
In order to obtain the transient power system measurement information, Wide Area Monitoring Systems (WAMS) should be able to collect Phasor Measurement Unit (PMU) data in a timely manner. Therefore along with the continual deployment of PMUs in Great Britain (GB) transmission system substations, a high performance communications infrastructure is becoming essential with regard to […]
In Mobile Ad hoc Networks (MANETs), system performance degrades when some switching nodes and/or communication links fail to operate. As a result, the performability (performance reliability) assessment of MANETs is very important. However, because of the impact of dynamic topology, the traditional system performability analysis methods, such as Dynamic Fault Tree (DFT) and Dynamic Reliability […]
Lifetime optimization and security are two conflicting design issues for multi-hop wireless sensor networks (WSNs) with non-replenishable energy resources. In this paper, we first propose a novel secure and efficient Cost-Aware SEcure Routing (CASER) protocol to address these two conflicting issues through two adjustable parameters: energy balance control (EBC) and probabilistic-based random walking. We then […]
In recent years, the range of sensing technologies has expanded rapidly, whereas sensor devices have become cheaper. This has led to a rapid expansion in condition monitoring of systems, structures,vehicles, and machinery using sensors. Key factors are the recent advances in networking technologies such as wireless communication and mobile ad hoc networking coupled with the technology to […]
The integration of social networking concepts into Internet of Things systems is a burgeoning topic of research that promises to support novel and more powerful applications. In this paper we present the social approach that the COSMOS project introduces in order to achieve enhanced services like discovery, recommendation and sharing between Things enriched with social properties. We investigate how typical notions […]
With rapid advances of scatter radio systems, the principle of reflection rather than active transmission employed by backscatter sensor networks, has emerged as a potential key enabler for low-cost, large-scale and dense ubiquitous sensor networks. Despite the presence of three different unknown channel links due to the bistatic setup (i.e., carrier emitter and receiver are dislocated), as […]
