Enhancement of Split Multipath Routing Protocol in MANET
Dhirendra Kumar Sharma,Sanjay Kumar Biswash,Chiranjeev Kumar
International Journal on Computer Science and Engineering , 2010,
Abstract: In the MANET, routing protocols are used to provide the specific path for sending the data packets. Multipath routing provides the multiple paths in the MANET. So, in this paper we enhance the performance of Split Multipath Routing protocols by using route update mechanism. This proposal is useful in route recovery process. In MANET for sending the data packets through alternate path takes more time incomparison with stale route that was broken. So, here we repair the broken route through route update mechanism process and reduce the delay through new updated path. In our proposal we are considering the high gain antenna terminal that adjust transmission range of each node and follow a new technique for route update mechanism. So, herewe provide a heuristic approach to reduce the delay metric and increase the performance of MANET.

Abstract: Mobile Ad Hoc Networks (MANETs) also called meshnetworks are self-configuring networks of mobile devicesconnected by wireless links. MANETs are deployed insituations where there is no existing infrastructure, such asemergency search and rescue, military, etc. Each applicationhas a different set of requirements. This paper considersenergy routing protocols and workload balancing techniquesfor improving MANET routing protocols and energyefficiency. We give routing protocol that employs loadbalancing technique to the MANET routing protocols withnode caching enhancement. For energy efficiency evaluationof the protocols with limited power supply, the primaryobjectives of MANET routing protocols are to maximizenetwork throughput, to maximize energy efficiency, maximizenetwork lifetime, and to minimize delay. The networkthroughput is usually measured by packet delivery ratio whilethe most significant contribution to energy consumption ismeasured by routing overhead which is the number or size ofrouting control packets. The simulation will be done usingNS2 network simulator.
The Efficient Ant Routing Protocol for MANET
Srinivas Sethi,Siba K.Udgata
International Journal on Computer Science and Engineering , 2010,
Abstract: In recent years, mobile computing and wireless networks have witnessed a tremendous rise in popularity and technological advancement. The basic routing problem in MANET deals with methods to transport a packet across a network from source node to destination node. Due to the dynamic nature of MANET, it is difficult to design effective routing algorithms. In this paper, we introduce a novel metaheuristic on-demand routing protocol Ant-E, using the Blocking Expanding Ring Search (Blocking-ERS) to control the overhead and local retransmission to improve the reliability in term of packet delivery ratio (PDR). This method enhances the efficiency of MANET routing protocol. Ant-E is inspired by the ant-colony optimization (ACO) used to solve complex optimization problems and utilizes acollection of mobile agents as “ants” to perform optimal routing activities. Exhaustive simulations are carried out and it is observed that, Ant-E performs better than other two on demand routing protocols like AODV and DSR.

Abstract: The mobile ad-hoc network (MANET) is a wireless unstructured network and this has mostly suggested for multimedia streaming efficiency. The hackers attacks are reduce the capacity and efficiency of network in MANET. There are various types of protocol are used for the communication in MANET, but security is lacking in those techniques and some insoluble problems present in MANET. In this paper exhibits, a layered protocol network for secured data transmission called Analyzed Virtual Routing Protocol (AVRP). This protocol used to provide more secured data transmission and this not disturbing data streaming in the network.

International Journal on Computer Science and Engineering , 2011,
Abstract: A MANET (Mobile Adhoc Network) consists of a collection of mobile nodes communicating with each other without any fixed infrastructure such as access points or base stations. MANETS are self organizing or self restoring. Network topology in MANETS is subject to continuous and precipitous (unpredictable) change. The limited bandwidth availability, energy constraints and highly dynamic topology make the routing process as exigent. The routing process in MANET relies (based) on the cooperation of individual nodes which constitute the network. In this paper, we have tried to remove the existence of misbehaving nodes that may paralyze or slows down the routing operation in MANET. This increases the efficiency of a network. Efficiency can be calculated by the parameters or factors such astransmission capacity, battery power and scalability. Here we are considering the most crucial factor named as transmission capacity of a node. In MANET, as the network size increases complexity of anetwork also increases. To overcome this we make network as modular. So the network becomes task specific which refer to a particular work only. This is the reason of infusing the concept of agents in anefficient network. This proposed protocol provides the most efficient and reliable route which may or may not be minimum hop count.

International Journal on Computer Science and Engineering , 2012,
Abstract: A Mobile Ad-Hoc Network (MANET) is a decentralized network of autonomous mobile nodes, able to communicate with each other over wireless links. Due to the mobility of the nodes, the topology ofthe network changes spontaneously, therefore use of conventional routing tables maintained at fixed points (routers) is not suggested. Such a network may operate in a standalone fashion. There are variousrouting protocols available for MANETs. The most popular ones are DSR, DSDV and ZRP .The zone routing protocol (ZRP) is a hybrid routing protocol that proactively maintains routes within a localregion of the network. ZRP can be configured for a particular network through adjustment of a single parameter, the routing zone radius. In this paper, we address the issue of configuring the ZRP to providethe best performance for a particular network at any time with the concept of eccentricity. The results illustrate the important characteristics of different protocols based on their performance and thus suggest some improvements in the respective protocol. The tools used for the simulation are NS2 which is the main simulator, NAM (Network Animator) and Tracegraph which is used for preparing the graphs from the trace files.
Energy Efficient Routing Protocol for MANET
International Journal of Computer Science Issues , 2012,
Abstract: In recent years, many energy-efficient routing protocols have been proposed. However, very little efforts have been taken in studying the energy consumption of individual node, overhead and route maintaining issues. While not considering the design of energy efficient routing protocol, it may perform very worst than the normal routing protocol. Here, we have proposed On Demand Based Energy Efficient Routing Protocol (ODBEERP). The main aim of proposed protocol is to discover the minimum power-limitation route. The power limitation of a route is decided by the node which has the minimum energy in that route. So compared with the minimum node energy in any other route, the minimum node energy in the minimum power-limitation route has more energy. We have also proposed a more accurate analysis to track the energy consumptions due to various factors, and improve the performance during path discovery and in mobility scenarios. The proposed protocol is evaluated with object oriented discrete event simulator environment. Simulation results shows that the ODBEERP achieves good throughput, less delay, high packet delivery ratio and good energy efficiency than the existing protocol PEER.

Abstract: Clustering in Mobile Ad Hoc Networks (MANETs)has much better utilization compared to theconventional system. Other than the highly activeand unbalanced nature of MANETs makes it hardfor the cluster based routing protocols to split amobile network into clusters and determination ofcluster heads for each cluster. In this paper, weanalyze and compare some of existing works oncluster based routing in MANETs. This paper alsocategorizes the clustering techniques and routingprotocols for ad hoc network. This paper givesadvantages and disadvantages of these on theobservation.

International Journal of Computer Science and Management Studies , 2012,
Abstract: Mobile ad hoc networks (MANET) can be defined as a collection of large number of mobile nodes that form temporary network without aid of any existing network infrastructure or central access point. Each node participating in the network, acts both as host and a router and must therefore is willing to forward packets for other nodes. The characteristics of MANET provides large amount of degree of freedom and self-organizing capability that make it completely different from other network. Due to this nature of MANET, design and development of secure routing is challenging task for researcher in an open and distributed communication environments. The main work of this paper is to address the security issue, because MANET is generally more vulnerable to various attacks, so we proposed a secure routing protocol for MANET, named ASRP (Authenticate Secure Routing Protocol) based on DSDV (Destination- sequence distance vector). This protocol is designed to protect the network from malicious and selfish nodes. We are implementing Extended Public key Cryptography mechanism in ASRP in order to achieve security goals.
