At present, the security issues on MANET have become one of the primary concerns. The MANET is more vulnerable to attacks as compared to wired networks due to distributed nature and lacks of infrastructure. Those vulnerabilities are nature of the MANET structure that cannot be removed easily. As a result, attacks with malicious intent have been and will be devised to exploit those vulnerabiliti...

Bandwidth-delay product (BDP) and its upper bound (BDP-UB) have been well-understood in wireline networks such as the Internet. However, they have not been carefully studied in the multi-hop wireless ad hoc network (MANET) domain. In this paper, we show that the most significant difference of computing BDP and BDP-UB in MANET is the coupling of bandwidth and delay over a wireless link, where on...

The Open Shortest Path First (OSPF) routingprotocol for IP networks performs inefficiently when operatedover multihop, broadcast-based radio channels such as IEEE802.11 in IBSS mode. These types of networks are known moregenerally as mobile ad-hoc networks (MANET). The InternetEngineering Task Force (IETF) OSPF working group has beenconsidering extensions to OSPF to enha...

Security is actually an essential issue for the secured conversation in between mobile nodes in a dangerous ecosystem. In dangerous situations adversaries can easily group active and inactive assaults opposing intercept able routing in implant inside routing information as well as data packets. In this specific document, we have pay attention to essential security symptoms within Mobile adhoc n...

Mobile ad-hoc network is a collection of mobile nodes that organize themselves into a network without any predefined infrastructure. The characteristics of MANET are dynamic topology; bandwidth and energy constrained and limited physical security. Due to the dynamic nature of the network, these networks can be easily vulnerable to attacks. Many type of attacks can threat the MANET and the class...

In this chapter, we introduce the mobile ad-hoc network (MANET) database by discussing its definition, historical background and scientific fundamentals. Existing related projects are presented and classified into two main categories, pedestrian and vehicular projects based on their target users. Two main paradigms (i.e., report pulling and report pushing) for answering queries in MANET databas...

Mobile Ad-hoc NETworks (MANETs) connect mobile wireless devices without an underlying communication infrastructure. Communications occur in a multi-hop fashion, using mobile devices as routers. Several MANET distributed applications require to exchange data (GPS position, messages, pictures, etc.) by using a topic-based publish-subscribe interaction. Participants of these applications can publi...

MANET stands for Mobile Ad hoc Network. It is a robust infrastructure less wireless network. It can be composed either by mobile nodes or by both fine-tuned and mobile nodes. In MANET routing protocols for both static and dynamic topology are utilized. There are several security issues in MANET. Due to this various types of attack can be triggered easily in MANET. Selective packet drop attack i...

Mobile Ad hoc Networks (MANET) due to its unpredictable topology and bandwidth limitations are Vulnerable to attacks. Establishing security measures and finding secure routes are the major challenges Faced by MANET. Security issues faced by ad hoc networks are node authentication, insider attack and Intrusion detection. Implementing security measures is challenging due to the presence of limite...

Ad-hoc networking is a concept in computer communications, which means that users wanting to communicate with each other form a temporary network, without any form of centralized administration. Each node participating in the network acts both as a host and as a router. The study of distributed network and mobile ad hoc network (MANET) are currently two hotspots in distributed computing and mob...
