In this paper we discuss about the improvement of security and privacy issues in wireless Ad-hoc network,wireless mesh network and wireless sensor network with the help of routing protocols, authentication and cryptographic tools. Ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies. Attacks on ad hoc network routing protocols d...

Ad hoc wireless networking is currently a hot research area, especially because there is an increasing need for connectivity “anywhere” and, in particular, “anyhow.” While traditional networks have fixed nodes with wired connections (either optical fibers or copper lines), ad hoc wireless networks can be described as multi-hop wireless networks with mobile nodes. However, the mobility condition...

The rapid advancement in wireless over wired has augmented the need for improving theQuality of Service (QoS) over such wireless links. However, the wireless ad hoc networkshave too low bandwidth, and establishing a QoS in these networks is a difficult issue. So,support of quality of service in ad hoc networks is the topical issue among the networkscience researchers. In this research we are go...

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 is comprised of mobile hosts that can communicate with each other using wireless links. It is also possible to have access to some host in a fixed infrastructure depending on the kind of the mobile ad hoc network. Mobile ad hoc networks can be realized by different networks such as body area network (BAN), vehicular ad hoc network (VANET), wireless sensor network (WSN). ...

Routing is a basic step for data exchange. In wireless ad-hoc networks each node acts as a router and executes a routing protocol. Wireless ad-hoc networks are highly resource constrained in terms of network topology, memory and computation power. The reliable data transfer is a difficult task in wireless ad-hoc networks because of resource constraints. A mobile ad-hoc network (MANET) is a kind...

A mobile ad hoc network is a collection of mobile wireless nodes that can dynamically form a network without necessarily using any pre-existing network infrastructure. In general, routes between nodes in an ad hoc network may include multiple hops. Due to the potential ease of deployment, many practical applications have been conceived for ad hoc networks, including personal area networking, ho...

As wireless networking products and ad-hoc networks become more popular, the resource usage in routing packets for other network users will become an issue for users and developers of ad-hoc wireless products. In this paper, we propose a novel monitoring tool calledWANMon (Wireless Ad-hoc Network Monitoring Tool). WANMon can be installed on a wireless node to monitor resource usage (such as net...
