Secure data transfer in mobile ad hoc network (MANET) against malicious attacks is of immense importance. In this paper, we propose a new enhanced trust model for securing the MANET using trust-based scheme that uses both blind and referential trust. order to do this, relationship function has be integrated with dynamic source routing (DSR) protocol making more secure. We thoroughly analyze DSR...

Optical Wavelength Division Multiplexed (WDM) technology is a very promising candidate to harness the enormous bandwidth offered by the optical fiber. WDM networks are being actively considered for deployment in future Wide Area Network (WAN) environments such as the Next Generation Internet, in order to satisfy the high bandwidth and low latency demands. A proper performance evaluation of the ...

The new DEVS-NS2 modeling and simulation environment supports both high and low levels of abstraction network modeling and simulation. DEVS (Discrete Event System Specification) is a well-defined mathematical formalism specification for structure and behavior of dynamic systems. The NS-2 is a discrete event network simulator, whose primary use is intended to build and run various detailed netwo...

Wireless networks are, in contrary to wired networks, a relatively new field of research in information technology. Nevertheless there exist some simulators able to deal with wireless networks. Simulators are commonly used since developing and testing of new protocols and algorithms is one of the major research topics. Since the results of these simulations should be as significant as possible,...

Underwater acoustic networks have the potential to support a wide variety of applications from facilitating communication between autonomous underwater vehicles to supporting the remote monitoring of underwater mining equipment or environmental conditions [1]. Even though underwater acoustics has been studied for many years, and communications technologies exist for underwater scenarios, intere...

Powerful personal devices provide the basis for ad-hoc networking among mobile users. Delay-tolerant Networking (DTN) enables such communication in spite of low node density—to reach an infrastructure network as well as for direct information exchange between peers. Numerous DTN routing protocols have been developed, and their analysis has shown different performance depending on the (human) mo...

A mobile ad hoc network is a continuously self-configuring, infrastructure-less network of mobile devices connected without wires. They use wireless connections to connect to various networks.One new type of ad-hoc network in Vehicular Ad-Hoc Network in which vehicles constitute the mobile nodes in the network. The ad-hoc protocols in Mobile Ad-Hoc network is already is introduced earlier. But ...

Routing Issues in MANET is one of the key areas of researches in Mobile Computing. This paper is mainly focused on evaluating AODV routing protocol in Grid Environment using Random Direction mobility model. We evaluate various QOS metrics such Average Throughput, End to End Delay, Jitter and Packet Loss. Random Direction Mobility is the mobility model proposed for movement of various MANET node...

An Ad-hoc network is a self-organized network, without a central coordinator, and which frequently changes its topology. In this paper, we have analyzed the performance of Mobile Ad-hoc Networks (MANET) under wormhole attack. Multiple QoS parameters have been considered here such as throughput, delay, packet delivery ratio, node energy and node density. The NS2 network simulator has been used a...
