In our day-to-day life, wireless technology plays a great role, because users move from place to place across the globe, it’s important to think about the type of network we can deploy quickly. Collection of two or more node forms A mobile ad-hoc network (MANET) without the aid of any centralized infrastructure. There are independent nodes that communicate without a wire in a mobile ad hoc network. Due to the behavior of nodes in MANET the time when node joining/leaving the network is unknown. This study focuses on improve performance of DSR protocol affected due to selfish nodes. So, identify path without any selfish node is the main issue for delivering a packet by selecting a reserved path. The algorithm counts the number of failed route request messages to aware the selfish node that causes failure on NS-2 simulator tools. The node is assigned to indicating the selfishness status of the node during route discovery. In this study the researcher conducts performance evaluation of existing DSR and modified one is assessed by using packet delivery ratio, and endto-end delay metrics and achieved very good result.

With the growth of multimedia business demand in commercial applications, providing QoS support in Ad Hoc network is more and more important. With the appearance of the business which has strict requirements on the QoS, to provide QoS guarantee in mobile Ad Hoc network will have more important significance. By researching the QoS guarantee mechanism research status of wireless Ad Hoc network, as well as the existing research results and the analysis of the problems remaining to be solved, this paper puts forward a new QoS routing protocol named ProDSR, which adds QoS guarantee mechanism extension to the dynamic source routing protocol (DSR). This protocol makes bandwidth, stability and hop count to be selection criteria for providing QoS guarantee, effectively improves the service quality of mobile Ad Hoc network.

Mobile Ad-hoc Network (MANET) is a dynamic wireless network without any infrastructures. The network is weak and vulnerable to many types of attacks. One of these attacks is BlackHole. In this attack, a malicious node advertises itself as having a high sequence number and a shortest path to a specific node to absorb packets. The effect of BlackHole attack on ad-hoc network using AODV as a routing protocol will be examined in this research. We also propose a new mechanism, called DPBA-AODV, to detect and prevent BlackHole attacks on AODV protocol. Simulation result, by using NS2, depicts the efficiency of our proposed mechanism in packet delivery ratio under the presence of BlackHole nodes.

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.

Routing protocol selection are the primary ways to design any wireless network. In Mobile Ad-hoc Network (MANET), the chosen protocol ought to be the best in terms information delivery and data integrity. Hence, the performance analysis of the protocol is the major step before choosing a specific protocol. In this paper, the performance analysis is applied to Ad-Hoc On-Demand Distance Vector protocol using Network Simulator2. Packet delivery ratio and energy are the two common measures used for the comparison of the performance of above protocol.

Now a day’s mobile ad-hoc network (MANET) is engaged by numerous scientists and endeavoring to be conveyed by and by. To accomplish this objective, these two components are a significant issue that we need to consider. The first is "overhead". As it were, messages that is not important to be sent when setting up a system association between versatile hubs. The following issue is the parcel sending rate from source to the goal hub that sufficiently high to ensure a successful system association. This paper is concentrating on improving the exhibition of the Location-Aided Routing Protocol (LAR) regarding overhead decrease by adjusting the calculation of the MANET course disclosure process. The consequence of the reproduction shows that the proposed convention can decrease overhead definitely, growing system lifetime and increment parcel sending rate while contrasting and other traditional conventions.

Introduction: The aim of the securing energy routing protocol, is to provide the countermeasures to the attacks par-ticularly to the black hole in mobile ad-hoc network, and enhancing the network performance metric throughput al-so reducing the end-to-end delay between the nodes in the network.To build the protocol that enhances the perfor-mance of the network by modifying the existing DSR protocol by introducing new route discovery mechanism in the proposed protocol. Method: The proposed protocol implementation has two phases, route request/reply phase and route confirm phas-es. During the route discovery process, the route discovery from the source to destination process are described by sending the RREQ packet from the source hub as shown in Fig. 1(a), when it does not have one accessible and crav-ings a route to a destination. The source node transmits the RREQ to its associate nodes and the destination node re-ply with RREP. When the source receives reply message, the source node respond with reverse path with a confirm RCON message and providing security to the nodes in the network. Results: To verify the performance of the proposed protocol against the existing DSR protocol are compared with respect to various network metrics like end-to-end delay and packet delivery ratio and validated the result by com-paring both routing algorithm using Network Simulator 2. Conclusion: The results of the proposed SERP strongly safeguard against the attacks in the network and the packet delivery ratio is increased compared with the DSR also the end-to-end delay is reduced in the proposed protocol. Discussion: Mobile ad-hoc networks are being dynamic in nature, it associates with issues relating to secure routing, energy and are generally vulnerable to several types of attacks. The DSR is one of the widely used reactive proto-cols available for the mobile ad-hoc network and the proposed work enhancing the security of the network in the existing pro
