This paper evaluate several routing protocols for wireless ad hoc network with packet level simulations in ns-2 environment. The protocol suite includes routing protocols specially designed for wireless ad hoc routing they are more traditional protocols, like link state and distance vector; used for dynamic networks, Performance is evaluated with respect to packets delivery, end-to-end delay an...

Recently an efficient clustering protocol has been reported [1] for mobile ad-hoc networks (MANET). The proposed clustered network has been shown to be more stable than the clustered networks as reported in [3] and [4]. In this paper, we have proposed a distance vector based multicast routing protocol for MANETs that are clustered following the idea of [1]. The proposed scheme needs much less a...

This paper proposes a key management scheme for MANET (Mobile Ad hoc NETworks) networks that uses asymmetric cryptography without requiring nodes to know the public keys of the other nodes and without requiring any kind of central server or certification authority. In addition, the paper presents a new method (“delayed verification”) to reduce the delays in route establishment for distance vect...

Mobile Ad-hoc Network (MANET) is a network of wireless mobile nodes which communicate with each other without any centralized control or established infrastructure. Routing is a critical task in MANET where the nodes are mobile. In this paper an attempt has been made to evaluate the performance of prominent routing protocol of MANET: Ad-hoc On-Demand Distance Vector Routing (AODV) and Improved ...

Mobile Adhoc Networks (MANETs) are infrastructure-less, dynamic network of collections of wireless mobile nodes communicating with each other without any centralized authority. A MANET is a mobile device of interconnections through wireless links, forming a dynamic topology. Routing protocols have a big role in data transmission across a network. Routing protocols, two major classifications are...

Wireless mesh network (WMN) operates both in infrastructure and ad-hoc mode. It provides extended network coverage based on heterogeneous wireless technologies through multi-hop communications. In WMNs, the routing mechanisms and network organization need to be improved so that optimal path discovery or different protocols adaptability can be achieved. Hybrid routing is a demanding issue to be ...

Mobile Ad hoc networks (MANETs) have several advantages compared to traditional wireless networks. These include ease of deployment, speed of deployment and decreased dependency on a fixed infrastructure. There have been many studies done in this area to improve the quality and efficiency of the routing protocols in MANETs. However unique characteristics of MANETs topology such as open peer-to-...
