A Mobile Ad-Hoc Network (MANET) is a self-configuring network of mobile nodes connected by wireless links to form an arbitrary topology without the use of existing infrastructure. In this paper, we have studied the effects of various mobility models on the performance of two routing protocols Dynamic Source Routing (DSR-Reactive Protocol) and Destination-Sequenced Distance-Vector (DSDV-Proactiv...

With the advent of Wireless Application Protocol (WAP) and 2.5/3G communication systems, the mobile device has become a window to the Internet. A natural interface to this mobile device is through speech. To address this need, a new European Telecommunications Standards Institute (ETSI) standard front-end has evolved for Distributed Speech Recognition (DSR). The goal of the ETSI DSR front-end i...

An ad hoc network is a wireless and infrastructure less network. Various routing protocols have been discussed so far to improve the routing performance and reliability. A detail study shows that performance of on demand Routing protocols AODV and DSR are better than table driven protocols .AODV and DSR still suffer some short coming problems due to longer set up time in case of link failure an...

We present SADSR (Security-Aware Adaptive DSR), a secure routing protocol for mobile ad hoc networks. SADSR authenticates the routing protocol messages using digital signatures based on asymmetric cryptography. The basic idea behind SADSR is to have multiple routes to each destination and store a local trust value for each node in the network. A trust value is assigned to each path based on tru...

Ad-hoc networks are frequently used to establish communication in improvised environments without requiring any fixed infrastructure. These networks are formed with the help of their constituent wireless nodes, which are expected to forward packets for other nodes according to a pre-agreed upon protocol. The Dynamic Source Routing (DSR) protocol is one such protocol that helps to create and mai...

Recently, many researchers have focused on the Ad-Hoc networks especially the routing protocols which include reactive and proactive routing protocols. The ultimate goal of routing protocols is forwarding data packet from the source to the destination. Consequently, several proactive routing protocols, such as routing information protocol (RIP), and reactive routing protocols, such as Dynamic S...

Vehicular Ad hoc Network (VANET) is the major area in ad hoc Network. The network is built with vehicle and rode side unit. The routing protocol is very helpful to transfer the data from source to destination node. The dynamic routing protocol is reactive on demand routing protocol which utilizes source routing and manage routes lively. It uses two phases: route discovery and route maintenance....

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes that can dynamically form a network without using any pre-existing fixed infrastructure. Due to the mobility of the nodes, routing in mobile ad hoc network is not an easy task. A Number of mobile ad hoc routing protocols have been introduced. A set of performance comparison done for the most widely used ad hoc routing prot...

Mobile Ad hoc NETwork (MANET) comprises of nodes, which are free to move randomly, yet cooperate to forward packets between source and destination over a multi-hop wireless network. Due to absence of any fixed node, each node acts as a router, providing routing capability for the MANET. Various protocols for discovery of routes between any two MANET nodes have been designed. These protocols are...

Mobile ad hoc network is a dynamic network. In this network the mobile nodes dynamically form a temporary network without any centralized administration or the use of any existing network infrastructure. A number of routing protocols like Ad Hoc On-Demand Distance Vector Routing (AODV), Dynamic Source Routing (DSR) and Destination-Sequenced Distance-Vector (DSDV) have been proposed. The Dynamic...
