Route discovery and maintenance in Mobile Ad-hoc Network (MANET) is a problem of long standing interest. In ad-hoc networks the Ad-hoc on demand Distance Vector (AODV) protocol assumes that discovered route is optimal and transmits data on it for the entire data session, whereas due to dynamic topology nodes change position dynamically, the optimum route may change. Thus, node mobility may give rise...
Mobile Ad hoc network is consists of mobile nodes and can organize them self without requiring any infrastructure. Due to wireless communication any node can join or leave network which causes lot of security constraint and due to limited battery many researchers are doing researches on energy saving routing in MANET. In OLSR there is need of selecting MPR set, which minimize unnecessary broadcast...
The mobile ad hoc network(MANET) brings great challenges in security due to its high dynamics, link vulnerability, and complete decentralization. As an important routing protocol used in ad-hoc network, Multicast Ad-hoc On Demand Distance Vector (MAODV) protocol is not sufficient for security requirements and vulnerable to attacks induced by the hostile environment. In this paper we discuss the impact...
Mobile Ad Hoc networks (MANETs) is composed of mobile wireless nodes that are self-organized. The infrastructureless and dynamic nature of these networks demand very efficient routing strategies to be implemented in order to provide reliable end-to-end communication. Different routing protocols have been proposed in literature, but all of them are restricted to certain topology and scale assumptions...
In MANET, the severe instability feature produced by mobility and wireless nature leads to the frequent change of network topology and influences network performance. In this paper, we propose an improved routing protocol - N3S-OLSR, which calculates MPR sets with combination of self-sensing information and hop count. Through self-sensing module, nodes obtain the network status information, and map...
With the ongoing progress of telecommunication has increased the want of mobility, wireless or mobile networks and this desire has already swapped the wired networks. The upcoming networks has totally different infrastructure and has different protocols and devices. These networks are infrastructure less and no dedicated protocols or devices are required to deploy such networks. The theme of this...
Routing in mobile ad hoc networks (MANETs) is central to their proper functioning. Network dynamics make the routing a real challenging task. Although a host of studies has been reported in the literature evaluating the performance of proposed routing algorithms, a deeper insight reveals some residual malfunctioning: wall effects, looping and inconsistency. In this paper, we first unleash the cover...
Proactive routing in MANETs induces high signaling overhead. Increasing the routing period size, while it reduces such an overhead, prevents to correctly track frequent changes in the topology and impacts the validity of routing as time goes farther from the start of the routing period. Routes' validity plays a central leveraging mission to enhance network performances as forwarding through incorrect...
Impact of nodes dynamically, randomly, frequently entering and leaving network on unreliable routing connection has been clearly described by a generalized routing reliability model according to measuring parameters of relative performance by studying on two-hop unit model presented in this paper. A new rate expression of node entering/leaving spindle region beta has been established by analyzing...
Routing in mobile ad hoc networks (MANETs) is central to their proper functioning. Mobility in such networks makes the routing a real challenging task. Routes validity plays a central leveraging mission to enhance network performances. Forwarding through incorrect routes not only results in traffic wandering inside the network without ever being able to be delivered to their ultimate destinations...

A new rate expression of node entering and leaving spindle region has been established by...
Based on the simulation paradigm, Acs et al proposed a formal model tailored to the security analysis of on-demand distance vector routing protocols in MANET, and a routing protocol, called ARAN, was proven secure in the model. We indicate the improper manipulations such as mergence of the adjacent adversarial nodes, the improper definition of correct system state in the model, and the flaw in the...
Mobile ad hoc networks (MANETs) generally adopt a peer-to-peer architecture in which the nodes themselves provide routing and services to the network. Disconnectivity with peer nodes, induced by mobility, power drains and damage makes route maintenance difficult and degrade the network's ability to offer services reliably to its peer nodes. In this paper, we present a routing scheme for proactive...
In the autonomous environment of mobile ad hoc network (MANET) where nodes are free to move around and depend on each other to initiate communication, cooperation among nodes is an essential component of a successful data transmission process. Since there is no central controller such as router to determine the communication paths in MANET, each node in the ad hoc network has to rely on each other...
