In mobile ad-hoc networks (MANETs), nodes use hello messages to detect neighbor nodes and to maintain link connectivity. In a typical MANET routing, a node broadcasts hello messages at a fixed interval. However, a fixed hello interval causes a long delay of neighbor discovery (too long hello intervals) or a more bandwidth waste by unnecessary protocol overhead (too short hello intervals). In this...
MANET's is exemplify at the time that the wireless networks in order that employ multihop wireless delivering along with are accomplished of performing beyond any settled infrastructure. So this type of infrastructure is called as framework less networks. The routing is an accurate chalking work in MANET's that the path is selected in network forward which sends the network service against origin...
On-demand routing protocols are the most commonly used protocols for the MANETs. It is the dynamic protocol and suitable for many applications. Wireless mobile adhoc networks have gained a lot of significance in wireless communications. The data transmission between the nodes in the wireless communication was established by adopting the routing protocol. The node in mobile ad-hoc networks acts as...
MANETs is a collection of mobile nodes. There infrastructure is neither fixed nor has any control station. So it is affected by various types of malicious attack. AODV is a standard MANETs protocol so every malicious node tries to attack on this routing protocol. A black hole attack is a type of malicious attack in which black hole node replies to route request packet with the highest destination...
Mobile ad hoc network is an arbitrary network in which all the nodes are mobile and consists of limited battery power and channel bandwidth. Ad hoc network often deployed in emergency situations, therefore saving resources i.e. power in such situations is prime importance. In this paper, an algorithm MAODV (Ad Hoc on demand distance vector routing using threshold power to route the packet) has been...
Mobile ad hoc network (MANET) has a distributed and uncontrolled nature in which all nodes are considered trusted and contribute in the route discovery process. Accordingly, MANET is vulnerable to many types of routing attacks. One of the most popular MANET routing protocol that is vulnerable to different attacks is ad hoc on demand distance vector (AODV) routing protocol. In this paper, a mobile...
Peer-to-peer file sharing routine in mobile ad hoc networks (MANETs) adapts to the opportunistic nature in lieu of disconnected Manets on the other hand fails to consider the social interests of mobile nodes voguish widespread site, which can be subjugated to mend the file searching efficacy. We put forward, SPOON (Social network based P2P content-based file sharing in mObile ad hOc Network) shares...
The wireless Ad-hoc network comprise of numerous wireless nodes communicating with each other without the need for a any single centralized administration, in such a scenario all the nodes potentially contribute to the routing process. A node can move anytime in an ad hoc scenario, as a result, such a network poses routing protocols which can adopt to dynamically changing network topology. To accomplish...
In the case of medical applications, the main requirement is to improve the control overhead and to achieve the reliable data transmission. A ZigBee based mobile patient monitoring network model is proposed, and its performance improvement is analysed based on reduced delay and enhanced throughput. We are focusing on the separate and comparative performance evaluation of AODV and DSR routing protocol...
Mobile ad hoc network is a collection of mobile nodes which are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. This paper examined routing protocols by varying CBR traffic but having identical...
MANET is gaining more popularity due to two main characteristics, dynamic topology and no requirement of centralized administration. But due to these two properties, MANET is highly prone to various security attacks. One of the most important categories of attack is the Denial of Service (DoS) and the most important attacks under this category are the Blackhole and Grayhole Attacks. Lot of research...
A Mobile ad hoc network is a collection of mobile nodes connected through wireless links forming an temporary network without fixed topology, centralized access point, infrastructure. In such a network, each node can act as a router and host simultaneously, it can move out or join in the network freely as required. Various routing protocols have been discussed so far in this paper a brief comparison...
The ad-hoc network is a collection of wireless mobile nodes without any support of a stationary infrastructure. Due to the node's mobility and the network topology changes to be kinetic, the network disconnection occur frequently. This paper proposes a variation of the AODV protocol, which selects CORE nodes using path's accumulation information, and then establishes multi paths based on CORE-node's...
This paper presents a comprehensive simulation study of well known On-demand routing protocols Ad hoc On demand Distance Vector (AODV), Table-driven routing protocol Destination Sequenced Distance Vector (DSDV) and Hybrid routing protocol Zone Routing Protocol (ZRP) in different mobility scenarios generated by Random Waypoint model. The performance of the three routing protocols is analyzed with respect...
Mobile ad hoc network is a collection of wireless mobile nodes that creates a dynamically wireless network among them without using any fixed infrastructure. Nodes are mobile and free to move, independent of each other which makes routing much difficult. The routing protocols in MANET should be more dynamic so that they quickly respond to topological changes. In this paper simulation based experiments...
The Mobile Ad Hoc Network (MANET) consists of a collection of wireless mobile nodes. These Mobile nodes are connected by wireless link. This network do not required any infrastructure or centralized access point such as base station. MANETS are highly venerable for Passive and Active Attacks because of their open medium, rapidly changing topology and lack of centralized monitoring. To protect the...
Wireless Mesh Networks (WMNs) consist of static router backbone which provide connectivity and coverage to mobile clients. They can also be viewed as a special case of wireless multi-hop Mobile Ad-hoc Networks (MANETs). The IETF group as well as the IEEE 802.11s working group have recommended applicability of several existing MANETs routing protocols for WMNs. However, in WMNs, client to client communications...
Topology change is the main factor that affects the network life time of Wireless Sensor Network (WSN) applications. In static WSN, the topology change is often caused by node failure which is due to energy depletion. However, in the Mobile WSN (MWSN), the main reason of the topology change is caused by the node movement. Since the mobile sensor nodes are limited in power supply and have a low radio...
An ad hoc network is a group of wireless mobile computers or nodes in which individual nodes cooperate by forwarding packets for each other to allow nodes to communicate beyond direct wireless transmission range. In this paper I presented the design and performance evaluation of a new on demand ad hoc routing protocol, called SWARM. SWARM used mechanisms of swarm intelligence to based select good...
Genetic Zone Routing Protocol (GZRP), a new multi path routing protocol for MANETs, is an extension of ZRP by using Genetic Algorithm (GA). GZRP uses GA on IERP and BRP parts of ZRP to provide a limited set of alternative routes to the destination in order to load-balance the network and robust when node/link failure occurs during the route discovery process. GZRP is studied for its performance and...
