Wireless networks nowadays play an important role in day today’s life. Every person wants to use the wireless networks for their daily routine work. The number of attacks seems to be increasing in nature day by day in Mobile Adhoc Networks (MANETs). In this paper we are going to design a three stage hybrid framework for IDS/IPS for MANETs. A new hybrid IDS/IPS is designed using evolutionary bas...

Mobile Ad hoc Networks (MANETs) play an important role in the pervasive computing to support a wide range of applications. MANETs are self-organizing networks formed spontaneously from a set of mobile devices without any pre-existing fixed infrastructure or administrative support. Network management plays a vital role in the well-being of any communications network. It becomes extremely importa...

Traditional infrastructure-based networks are formed around an infrastructure of static, dedicated components that connect the individual end points such as desktop computers and servers. The exponential rise in the number of wireless communication devices will render the provision of infrastructure-based solutions infeasible and researchers have been investigating the provision of alternative ...

In mobile ad hoc networks, the absence ofinfrastructure and the consequent absence of authorizationfacilities impede the usual practice of establishing a practicalcriterion to distinguishing nodes as trusted and distrusted.Since all nodes in the MANETs would be used as router inmulti-hop applications, secure routing protocols have vital rulein the security of the network. So evaluating the perf...

Cognitive radio (CR) technology will have significant impacts on upper layer performance in mobile ad hoc networks (MANETs). In this paper, we study topology control and routing in CR-MANETs. We propose a distributed Prediction-based Cognitive Topology Control (PCTC) scheme to provision cognition capability to routing in CR-MANETs. PCTC is a midware-like cross-layer module residing between CR m...

Research on mobile ad hoc networks (MANETs) has become a hot research topic since the middle 1990's. Over the first decade, most research focused on networking techniques, ignoring data management issues. We, however, realized early the importance of data management in MANETs, and have been conducting studies in this area for 15 years. In this review, we summarize some key technical issues rela...

Mobile ad-hoc networks (MANETs) are the wireless ad-hoc networks which enclose sovereign group of wireless mobile nodes. The communication is relayed via routes which are discovered using various routing protocols. Diverse routing protocols have been proposed so far in MANETs. Likewise, swarm intelligence (SI) based ant colony optimization (ACO) technique have various routing protocols which ca...

Quality of service (QoS) support in Mobile Ad-hoc NETworks (MANETs) is a challenging task. Most of the proposals in the literature only address certain aspects of the QoS support, e.g., QoS routing, QoS medium access control (MAC) and resource reservation. However, none of them proposes a QoS model for MANETs. Meanwhile, two QoS models have been proposed for the Internet, viz., the Integrated S...

A Mobile Ad hoc Network (MANET) is a system of wireless mobile nodes that dynamically self-organize in arbitrary and temporary network topologies. Both selfish and privacy issues have been identified as two crucial human factors for the wide acceptance of MANETs. Security has become a primary concern in order to provide protected communication between mobile nodes. In this work we present a rev...

TCP optimization in mobile ad hoc networks MANETs is a challenging issue because of some unique characteristics of MANETs. Packet losses in MANETs are mainly due to congestion and frequent link failures but in case of wired networks packet losses are mainly due to congestion. To optimize TCP in MANETs we use congestion control and avoidance algorithms. In this paper, we describe an NS2based sim...
