AbstractNowadays, most recommender systems are based on a centralized architecture, which can cause crucial issues in terms of trust, privacy, dependability, and costs. In this paper, we propose a decentralized and distributed MANET-based (Mobile Ad-hoc NETwork) recommender system for open facilities. The system is based on mobile devices that collect sensor data about users locations to derive implicit ratings that are used for collaborative filtering recommendations. The mechanisms of deriving ratings and propagating them in a MANET network are discussed in detail. Finally, extensive experiments demonstrate the suitability of the approach in terms of different performance metrics.

Mobile adhoc networks (MANETs) have drawn attention to multitudinous consideration because of the univerality of mobile devices as well as the developments in wireless era. MANET is a peer-to-peer multi hop cellular wireless era community which does not have both difficult and speedy infrastructure and a relevant server. Every vertex of a MANET performs like a router and communicates with every unique. There exist numerous information duplication strategies which were presented to reduce the execution squalor. All are concluded that everyone cell vertices cooperate completely from the perspective of sharing their memory vicinity. But, via a few methods few vertices might additionally behave selfishly and determine simplest to cooperate in part or never with different vertices. The selfish vertices ought to then lessen the overall information approachability within the network. From this work, we try to take a look at the influence of selfish vertices in a mobile ad hoc community in terms of reproduction issuance i.e Selfish nodes are dealt with in replica allocation.

The Impact

Routing protocols can be tested in realistic conditions of Mobile Ad-hoc network (MANET)). The performance of MANET depends on different parameters such as used number of nodes, mobility speed, routing protocols, mobility model and energy models etc. In this paper, researchers made an effort to analyze the impact of energy and mobility on the performance of AODV and DSR routing protocols with varying mobility speed under random waypoint mobility model and radio energy models in the MANET. Detailed simulations have been carried out using QualNet simulator for 50 nodes. Performance of AODV and DSR routing protocols has been analyzed under the premise of performance metrics namely average throughput, average end to end delay and average jitter using CBR traffic patterns.

Mobility models are used to evaluated the network protocols of the ad hoc network using the simulation. The random waypoint model is a model for mobility which is usually used for performance evaluation of ad-hoc mobile network. Mobile nodes have the dynamic mobility in the ad hoc network so the mobility model plays an important role to evaluate the protocol performance.In this article, we developed modify random waypoint mobility (MRWM) model based on random waypoint for the mobile ad hoc network. In this article, the comparative analysis of modifying random waypoint mobility and random waypoint model on the ad hoc On-Demand Distance Vector (AODV) routing protocol has been done for large wireless ad hoc network (100 nodes) with the random mobile environment for the 1800s simulation time. To enhance the confidence on the protocol widespread simulations were accomplished under heavy traffic (i.e. 80 nodes) condition. The proposed model protocol has been investigated with the performance metrics: throughput; packet delivery ratio; packet dropping ratio; the end to end delay and normalized routing overhead. The obtained results revealed that proposed modify random waypoint mobility model reduces the mobility as compared to the random waypoint mobility model and it is trace is more realist.

The security in a mobile ad hoc networks is more vulnerable and susceptible to the environment, because in this network no centralized environment for monitoring individual nodes activity during communication. The intruders are hacked the networks either locally and globally. Now a day’s mobile ad hoc network is an emerging area of research due to its unique characteristics. It’s more vulnerable to detect malicious activities, and error prone in nature due to their dynamic topology configuration. Based on their difficulties of intrusion detection system, in this paper proposed a novel approach for mobile ad hoc network is Fuzzy Based Intrusion Detection (FBID) protocol, to identify, analyze and detect a malicious node in different circumstances. This protocol it improves the efficiency of the system and does not degrade the system performance in real time.This FBID system is more efficient and the performance is compared with AODV, Fuzzy Cognitive Mapping with the following performance metrics: Throughput, Packet Delivery Ratio, Packets Dropped, Routing overhead, Propagation delay and shortest path for delivering packets from one node to another node. The System is robust. It produces the crisp output to the benefit of end users. It provides an integrated solution capable of detecting the majority of security attacks occurring in MANETs.

MANET (Mobile Ad-Hoc Network) is a network consisting of several mobile devices that communicates through wireless network without router. Mobile devices are not only used for voice and data transfer, but also as a router. This research develops a mobile application based on MANET that can communicate without network infrastructure. It can be used when the natural disaster damages the network infrastructure.

Abstract Mobile Ad-hoc NETwork (MANET) is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers in wired networks or access points in managed wireless networks. One of the major issue and challenging area in MANET is the process of routing due to dynamic topologies and high mobility of mobile nodes. The efficiency and accuracy of a protocol depend on many parameters in these networks. In addition to other parameters node velocity and propagation models are among them. Calculating signal strength at the receiver is the responsibility of a propagation model while the mobility of nodes is responsible for the topology of the network. A huge amount of loss in performance is occurred due to the variation of signal strength at the receiver while increasing and decreasing the distance of nodes. In this paper, a novel approach is identified and portrayed of the said propagation models based on distance from each other. It has been analyzed to check distance based performance evaluation of Two Ray Ground and Free Space Radio Wave Propagation Models on the performance of Ad-hoc On-demand Distance Vector (AODV) Routing Protocol in MANET. The simulation has been carried out in (Network Simulator-2) NS-2 by using performance metrics that are Average Throughput (kpbs), Average Latency (milliseconds) and Average Packet Drop (packets). The results predicted that propagation models and mobility have a strong influence on the performance of AODV in considered distance based scenario.

Mobile Ad hoc Network (MANET) is an infrastructure fewer networks built on a multihop conveying idea. It transmits data from base node to end node. Because MANETS don’t have any fixed infrastructure and it works in a distributed manner. For efficient communication, many routing protocols are used in MANET. Routing protocols are to find a new route to transmit data from base to accurate end through the midway nodes. Every in-between node is act as a router. So, this paper is covers the routing protocols AODV, DSR, DSDV and OLSR to keep current routing information from every node to each other nodes. The purpose of this paper to offers a relative study of routing protocols in MANET and energy aware performance metrics are analyzed on two routing protocols of AODV and DSDV.
