The major attack on wireless sensor network is Denial–of-service (DoS). DoS attacks like packet dropping, collisions, interference, false route, flooding and buffer overload can destroy the network. One of the most important factors of DoS attacks is packet dropping. Packet dropping means drop packets to interrupt the packet transmission process which make the communication diminish. This paper...

Recent advances in generalized multiprotocol label switching (GMPLS) [1,12] and the extensive study and understanding of packet-over-optical network architecture, has made it possible for a single integrated control plane to manage the resources of the packet network and underlying optical transport network in an unified manner. This opens up the possibility for coordinated actions across the t...

When the data is transferred over the network, a reliable end packet delivery is one of basic requirement of both user and network but there are many major causes that can result packet loss, such as Congestion over the network. Because of this there is requirement of some methodology that can reduce the packet loss and return reliable data transmission over the network. In this paper, the prop...

Distributed denial-of-service (DDoS) attacks are network-wide attacks that cannot be detected or stopped easily. They affect “natural” spatiotemporal packet traffic patterns, i.e. “natural distributions” of packets passing through the routers. Thus, they affect “natural” information entropy profiles, a sort of “fingerprints”, of normal packet traffic. We study if by monitoring information entro...

Packet sniffers are designed to intercept network traffic in shared communication channels. This is accomplished by re-configuring network interface cards to permit device drivers to process all network traffic, including packets that are not addressed to the host computer. Packet sniffing is primarily used in intrusion detection, network management, wiretapping and hacking. This paper describe...

This paper proposes a novel traffic engineering method for improving the throughput characteristics of optical packet forwarding in an optical packet / path integrated network. This method is based on bypassing optical packets rejected from a highly-loaded optical packet switch onto one of the adjacent packet switches via an optical path to increase the network throughput. Since the formation o...
