Ad-hoc wireless networks consist of mobile nodes interconnected by multi-hop wireless paths. Unlike conventional wireless networks, ad-hoc networks have no fixed network infrastructure or administrative support. Because of the dynamic nature of the network topology and limited bandwidth of wireless channels, Quality-of-Service (QoS) provisioning is an inherently complex and difficult issue. In ...

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 focus of this paper is on presenting new results on throughput capacity of wireless ad hoc networks with multicast traffic. In seminal works [1], Gupta and Kumar introduced a new line of research. It is about the asymptotic throughput capacity of dense wireless ad hoc networks as a function of the number of nodes in the network. First, we present results on asymptotic behavior of a random a...

Transmission control protocol (TCP), which provides reliable end-to-end data delivery, performs well in traditional wired network environments, while in wireless ad hoc networks, it does not perform well. Compared to wired networks, wireless ad hoc networks have some specific characteristics such as node mobility and a shared medium. Owing to these specific characteristics of wireless ad hoc ne...

Intrusion detection for mobile ad hoc network (MANET) is a complex and difficult task due to the nature of the network. The mobile ad hoc network is vulnerable due to its features of open medium, cooperative algorithms, dynamic changing topology, lack of centralized monitoring and management point. The mobile ad hoc networks (MANETs) combine wireless communication with high degree of node mobil...

Ad hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. We compare the performance of three routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR) , Ad Hoc On-Demand Distance Vector Routing (AODV), location-aided routing(LAR1).The performance differentials are analyzed usi...

Wireless Networking is becoming very popular and interesting technology especially in these days as everyone wants wireless connectivity at anywhere anytime. It contains numerous wireless network technologies such as WiFi, WiMax, HSDPA and WiBro etc. Based on structural arrangement, wireless networks are categorized into two main categories: fixed infrastructure wireless networks and infrastruc...
