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

Abstract
Two of the existing reliable transport layer protocols for wireless sensor networks- Distributed TCP Caching and Event To Sink Reliable Transport protocol, does not score well in terms of efficiency. Considering the total number of retransmissions as a QoS parameter for efficiency, our protocol k-RTP ( k Hop Reliable Transport Protocol ) is promising. In our protocol only the nodes do cache the packets and retransmit them in case of packet loss. The value of k is varied dynamically depending on the rate of packet loss in the network. ....etc

As sensor networks edge closer towards wide-spread deployment, security issues become a central concern. Sensor networks have been identified as being useful in a variety of domains to include the battlefield and perimeter defense. So far, much research has focused on making sensor networks feasible and useful, and has not concentrated on security.

We present a suite of security building blocks optimized for resource constrained environments and wireless communication. SPINS has two secure building blocks: SNEP and ?TESLA SNEP provides the ....etc

Communication protocols belong to the broad class of d lscrete-event
systems. Other examples of these systems are flexible manufacturing systems,
process control systems, office information systems and VLSI circuits. The
behaviour of all of these systems can be characterized by starting and
ending times,these systems inherently involve the
consideration of the notions of concurrency, nondeterminism, time and
Therefore the formal description technique (FDT) used to the
description of a discrete-event system should be able to express these ....etc

SNMP

Introduction:

Simple Network Management Protocol (SNMP) is a UDP-based network protocol. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. SNMP is a component of the Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF). It consists of a set of standards for network management, including an application layer protocol, a database schema, and a set of data objects.

SNMP is part of the Internet network management arch ....etc

Protocol Scrubbing: Network Security Through Transparent Flow Modification
Abstract: This paper describes the design and implementation of protocol scrubbers. Protocol scrubbers are transparent, interposed mechanisms for explicitly removing network scans and attacks at various protocol layers. The transport scrubber supports downstream passive network-based intrusion detection systems by converting ambiguous network flows into well-behaved flows that are unequivocally interpreted by all downstream endpoints. The fingerprint scrubber restricts ....etc
