Abstract

In this paper, we propose an Identity (ID)-based Secure Routing Scheme for secure routing in wireless ad-hoc networks. It make use of Identity based Signature scheme and hash chains to secure the AODV (Ad-hoc on demand distance vector routing) messages. We have used ID based Signature scheme for the immutable fields, that is the fields that remain same throughout the journey of the routing packet and Hash Chains for the mutable fields (fields which changes from node to node) e.g. Hop Count. This system has the following adva ....etc

ABSTRACT
The vision of nomadic computing with its ubiquitous access hasstimulated much interest in the Mobile Ad Hoc Networking(MANET) technology. However, its proliferation strongly dependson the availability of security provisions, among other factors. In theopen, collaborative MANET environment practically any node canmaliciously or selfishly disrupt and deny communication of othernodes. In this paper, we present and evaluate the Secure MessageTransmission (SMT) protocol, which safeguards the datatransmission against arbitrary malic ....etc

Abstract
In mobile ad hoc networks, due to unreliable wireless
media, host mobility and lack of infrastructure, providing secure
communications is a big challenge in this unique network environment.
Usually cryptography techniques are used for secure
communications in wired and wireless networks. The asymmetric
cryptography is widely used because of its versatileness (authentication,
integrity, and confidentiality) and simplicity for key distribution.
However, this approach relies on a centralized framework
of public key infras ....etc

Multipath Distance Vector Zone Routing Protocol for Asymmetric Mobile Ad-Hoc Networks
Abstract—
Most of the ad hoc routing protocols assume that all wireless networks aresymmetric (bidirectional links). In reality any practical network has some links may beunidirectional and hence the network is asymmetrical rather than symmetrical. The presenceof such links can reduce the performance of the existing protocol and could lead to networkclogging. In this paper we introduce a Multipath Distance Vector Zone R ....etc

Abstract:
Secure distance-based localization in the presence of cheating beacon (or anchor) nodes is an important problem in mobile wireless ad hoc and sensor networks. Despite significant research efforts in this direction, some fundamental questions still remain unaddressed: In the presence of cheating beacon nodes, what are the necessary and sufficient conditions to guarantee a bounded error during a two-dimensional distance-based location estimation? Under these necessary and sufficient co ....etc

Abstract
Localization is an essential and important research issue in wireless sensor networks (WSNs). Most localization schemes
focus on static sensor networks. However, mobile sensors are required in some applications such that the sensed area can be
enlarged. As such, a localization scheme designed for mobile sensor networks is necessary. In this paper, we propose a localization
scheme to improve the localization accuracy of previous work. In this proposed scheme, the normal nodes without location information
can estimate their ....etc

A Novel Secure Communication Protocol for Ad Hoc networks
Abstract: An ad hoc network is a self organized entity with a number of mobile nodes without any centralized access point and also there is a topology control problem which leads to high power consumption and no security, while routing the packets between mobile hosts. Authentication is one of the important security requirements of a communication network. The common authentication schemes are not applicable in Ad hoc networks. In this paper, we propose a secure communication prot ....etc

This paper introduces a message forwarding algorithm for search applications within mobile ad hoc networks that is based on the concept of selecting the nearest node from a set of designated nodes. The algorithm, which is called Minimum Distance Packet Forwarding (MDPF), uses routing information to select the node with the minimum distance. The goal of the proposed algorithm is to minimize the average number of hops taken to reach the node that holds the desired data. Numerical analysis and experimental evaluations using the network simulation ....etc

SECURE WIRELESS SENSOR NETWORKS - ROBUST OF WSN ATTACKS AND SECURE LOCALIZATION SCHEME
ABSTRACT
The application of wireless sensor networks (WSN), sensors are deployed un-tethered in hostile environments. For location aware WSN applications, it is essential to ensure that sensors can determine their location, even in the presence of malicious adversaries. Our paper mainly projects the problem of enabling sensors of WSN to determine their location in an un-trusted environment. The localization schemes based ....etc
