The performance of many envisioned applications in shortrange wireless ad hoc networking will critically rely on the promptness of the self-configuring network procedures. In that sense, a fundamental problem in ad hoc networks, is the device discovery and/or network initialization. In this paper we propose a randomized distributed algorithm for rapid device discovery during the deployment of a...

Wireless Ad Hoc network suffers from a lot of problems such as low throughput and hot and dead spots. Gupta and Kumar have established the throughput of ad hoc networks only for the unicast pattern which is not effective in application. And they did not take the possible network coding and broadcast and multicast pattern into consideration. There has been interest in applying network coding in ...

The network structures have changed significantly in the recent years. In spite of the wireless network challenges namely: changes in network topology, high error rates, power restrictions, bandwidth constraints and issues with link capacity, these networks have become popular. Researchers have contributed to a great extent to solve these challenges with innovative solution to support robust an...

Usually, Ad Hoc network studies concentrate on network layer procedures, such as routing, and performance of the upper layer protocols of the network. The research on ad hoc networking is mostly focused on the network layer solution and the characteristics of the used link technology are analyzed only superficially. Moreover, practically all ad hoc network simulators and testbeds assume IEEE 80...

Security is a major concern in wireless technology and this work deals with security in wireless mobile ad-hoc network by using Novel IDS in Open Shortest Path First (OSPF) routing protocol. We are bounding wireless mobile ad-hoc network nodes to getting updates from unknown or unwanted nodes on the same network through routing table; we are using a Novel intrusion detection technique with the ...

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...

A Wireless Ad hoc Network is a collection of wireless nodes forming a self-configuring network lacking of using any obtainable transportation. Since Wireless Ad Hoc Networks are not currently deployed on a large scale, research in this area is generally simulation based. Among other simulation parameters, the mobility model plays a significant role in determining the protocol performance with t...

A mobile ad hoc network is an autonomous wireless network which consists of mobile nodes without any base stations. Many routing schemes and services have been proposed for mobile ad hoc networks. However, since these schemes tend to be evaluated through simulation experiments, it is not known whether they work effectively in real environments or not. Therefore, in order to verify their practic...

On the basis of analysis on the scene files of mobility models in Ad Hoc network, the paper presents a network topology snapshots capturing method to obtain the Ad Hoc network topology architecture at any moment. Through analyzing on the Ad Hoc network topology snapshots, some dynamic characteristic parameters of Ad Hoc network, such as the number of network topology in steady state or unsteady...

MANET stands for Mobile Ad hoc Network. An ad hoc network is often referred to as an “infrastructure less” network, because the network does not need fixed routers [1]. These nodes are mobile communicating through wireless medium. Each ad hoc node may be capable of acting as a router. It’s characterized by multi-hop wireless connection and frequently changing networks. In this paper we evaluate...
