Route falsification attacks are easy to launch in wireless ad hoc networks with on demand routing protocols that employ network-wide flooding of control packets for route discoveries. Colluding insider malicious nodes with no special hardware capability can use packet encapsulation and tunnelling to create bogus short-cuts in routing paths and influence data traffic to flow through them. The cu...

Human society is a complex and most organized networks, in which many communities have different cultural livelihood. The creation/formation of one or more communities within a society and the way of associations can be mapped to MANET. By involving human characteristics and behavior, surely it would pave a new way, for further development. In this paper we have presented a new approach called ...

The need to support real-time and multimedia applications in mobile ad hoc networks (MANETs) has increased dramatically over the last few years. There are many challenges in supporting QoS for MANETs. The contribution of this paper is a new framework based on the cross-layer design and integration between a new routing protocol and other components that deal with different types of traffic. We ...

This paper presents a performance evaluation of Wireless Sensor Networks (WSN) based on Impulse Radio Ultra Wideband (IR-UWB) over a new simulation platform developed for this purpose. The simulation platform is built on an existing network simulator: Global Mobile Information System Simulator (GloMoSim). It mainly focuses on the accurately modeling of IR-UWB PHYsical (PHY) and Medium Access Co...

A mobile ad hoc network (MANET) is an autonomous network that consists of mobile nodes that communicate with each other over wireless links. In the absence of a fixed infrastructure, nodes have to cooperate in order to provide the necessary network functionality. One of the principal routing protocols used in Ad hoc networks is AODV (Ad hoc On demand Distance Vector) protocol. The security of t...

AbstrAct: In order to provide quality delivery to delay sensitive applications such as voice and video, it is extremely important that mobile Ad Hoc networks provide quality of service (QoS) support in terms of bandwidth and delay. Most existing routing protocols for mobile Ad Hoc networks (MANETs) are designed to search for the shortest path with minimum hop counts. However, the shortest route...

In this work, we are interested in improving the performance of constructive network coding schemes in lossy wireless environments. We propose INC an approach that combines inter-session and intra-session network coding and has two strengths. First, the error-correcting capabilities of intra-session network coding make our scheme resilient to loss. Second, redundancy allows intermediate nodes t...

An Ad-Hoc network is a collection of mobile wireless nodes, forming a temporal network without the help of any centralized administration. Nodes in mobile ad-hoc network are free to move and organize themselves in an arbitrary fashion. Each user is free to roam about while communicating with others. In mobile Ad-hoc network, the reactive and proactive routing protocols face many challenges whic...

In this paper the problem of selecting optimal paths in a MCMI (Multi-Channel Multi-Interface) WMN (Wireless Mesh Network) is considered. The WMNs are characterized by high dynamic range of the received signal level, especially in the indoor environment. To improve the existing routing metrics and track fast changes that occur in the link state, a corresponding parameter based on the received s...

In this paper, we study the effect of routing protocols on the performance of Media Access Control (MAC) protocols in Mobile Ad hoc Networks (MANET). Three well known MAC protocols such as 802.11, Carrier Sense Multiple Access (CSMA) and Multiple Access with Collision Avoidance (MACA) are considered for performance study. The main focus of this paper was to study how the Node Transition Probabi...
