Abstract
A wireless ad hoc sensor network consists of a collection of wireless sensor nodes which dynamically exchange data among themselves without the reliance on a fixed base station or a wired backbone network. Sensor nodes are typically distinguished by their limited power, processing and memory resources. However, routing in these networks faces a number of security threats. One such threat is the wormhole attack. In this attack, a malicious node captures packets from one l ....etc

Lazy Flooding: A New Technique for Information
Dissemination in Distributed Network Systems - IEEE/ACM TRANSACTIONS ON NETWORKING, VOL. 15, NO. 1, -java


Abstract—
Flooding is a commonly used technique for network
resource and topology information dissemination in the data communication
networks. However, due to the well-known –squared problem it causes network delay in response or even congestion. We propose a new flooding technique, called Lazy Flooding; it floods only when links reach a certain status. It significantly cuts down ....etc

Abstract:
To secure a mobile ad hoc network (MANET) inadversarial environments, a particularly challenging problem is how to feasibly detect and defend possible attacks on routing protocols, particularly internal attacks, such as a Byzantine attack. In this paper, we propose a novel algorithm that detects internal attacks by using both message and route r ....etc

Preface
A large class of routing protocols for MANETs, namely, reactive protocols, employs some form of caching to reduce the no. of route discoveries .the simplest form of caching is based on associating a timeout with each cache entry.
Such timer based cache scheme can increase the protocol efficiency. However the timeout is not well tuned, a sever performance degradation arises as entries are removed either too early or too late from the cache .
In this paper, we address the problem designing a proactive protoc ....etc

Abstract
In a bandwidth-flooding attack, compromised sourcessend high-volume traffic to the target with the purpose of causingcongestion in its tail circuit and disrupting its legitimate communications.In this paper, we present Active Internet Traffic Filtering(AITF), a network-layer defense mechanism against such attacks.AITF enables a receiver to contact misbehaving sources and askthem to stop sending it traffic; each source that has been asked tostop is policed by its own Internet service provider (ISP), which ensuresits compliance. ....etc

Novel Defense Mechanism Against Data Flooding Attacks In Wireless Ad Hoc Networks

– Consumer Electronics – Java

Mobile users like to use their own consumer electronic devices anywhere and at anytime to access multimedia data. Hence, we expect that wireless ad hoc networks will be widely used in the near future since these networks form the topology with low cost on the fly. However, consumer electronic devices generally operate on limited battery power and therefore are vulnerable to security threats like data flooding attacks. ....etc

BANDWIDTH ESTIMATION FOR IEEE 802.11 BASED ADHOC NETWORK-MOBILE COMPUTING

Abstract: Since 2005, IEEE 802.11-based networks have been able to provide a certain level of quality of service (QoS) by the means of service differentiation, due to the IEEE 802.11e amendment. However, no mechanism or method has been standardized to accurately evaluate the amount of resources remaining on a given channel. Such an evaluation would, however, be a good asset for bandwidth-constrained applications. In multihop ad hoc networks, such evaluation becomes ev ....etc
