An Acknowledgment-Based Approach For The Detection Of Routing Misbehavior In MANETs
Abstract: We study routing misbehavior in MANETs (Mobile Ad Hoc Networks) in this paper. In general, routing protocols for MANETs are designed based on the assumption that all participating nodes are fully cooperative. However, due to the open structure and scarcely available battery-based energy, node misbehaviors may exist. One such routing misbehavior is that some selsh nodes will participate in the route discovery and maintenance processes but refuse to for ....etc

Adhoc networks are a new wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected. The military tactical and other security-sensitive operations are still the main applications of ad hoc networks, although there is a trend to adopt ad hoc networks for commercial uses due to their unique properties. One main challenge in design of these networks is their vulnerability to security attacks. In ....etc

Reliable Multicasting in MANETs

Abstract
Multicasting is the transmission of datagramâ„¢s (packets) to a group of zero or more hosts identified by a single destination address. Maintaining group membership information and building an optimal multicast distribution structure (typically in the form of a routing tree) is challenging even in wired networks. However, nodes are increasingly mobile. One particularly challenging environment for multicast is a mobile ad-hoc network (MANET). This report provides an in-dept ....etc

Mobile ad-hoc networks (MANETs) are becoming more popular due to their ability to model interesting aspects of real wireless networks. It is easy and cheap to build such networks because no other equipment or infrastructure are required besides the mobile devices. An MANET is composed of a set of nodes distributed in the plane. A signal sent by any node can be received by all the nodes within its transmission range, which is usually taken as one unit distance. One of the primary issues related to MANETs is the development of efficient routing a ....etc

Route Stability in MANETs under the Random Direction Mobility Model

Abstract:


A fundamental issue arising in mobile ad hoc networks (MANETs) is the selection of the optimal path between any two nodes. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce the latency and the overhead due to route reconstruction. In this work, we study both the availability and the duration probability of a routing path that is subject to page link failures caused by node mobility. In particular, ....etc

The paper focuses on a cooperative environment in wireless ad hoc networks, where mobile nodes share information in a peer-to-peer fashion. Nodes follow a pure peer-to-peer approach (i.e., without the intervention of servers), thus requiring an efficient query/response propagation algorithm to prevent network congestion. The main contribution of the paper is the proposal of a novel solution, called Eureka, that identifies the regions of the network where the required information is more likely to be stored and steers the queries toward those re ....etc

Aim:

Due toopen structure and scarcely available battery-based energy,node misbehaviors may exist.One such routing misbehavior is that some selfish nodes will participate in the route discovery and maintenance processes but refuse to forward data packets.Here,we propose the 2ACK scheme that serves as an add-on technique for routing schemes to detect routing misbehavior and to mitigate their adverse effects.
