- Why DoS and DDoS attacks are the plague of the Internet
- Could DDoS be stopped?If ISPs simply denied "flooding" to go outside of their networks??ISPs now often have variable bandwidth allowances for users (DSL, cablemodem) based on the package they pay for to limit their bandwidth.Could an ISP not configure their network to allow only a limited amount of DDoS-style protocol...

- Efficient Localization in Mobile Wireless Sensor Networks
- The proposed Dynamic Reference Localization DRL is a distributed range-free localization approach. In order to save communication cost in localization, DRL reduces information flooding among nodes by dynamically changing each seed's flooding-hop to limit seed flooding in a local area; however, it still maintains the whole coverage. In addition, DRL...

- MISTRAL: Efficient Flooding in Mobile Ad-Hoc Networks
- Flooding is an important communication primitive in mobile ad-hoc networks and also serves as a building block for more complex protocols such as routing protocols. This paper proposes a novel approach to flooding, which relies on proactive compensation packets periodically broadcast by every node. The compensation packets are constructed from...

- Modeling the Performance of Flooding in Wireless Multi-Hop Ad Hoc Networks
- One feature common to most existing routing protocols for wireless mobile ad hoc networks, or MANETs, is the need to flood control messages network-wide during the route acquisition and maintenance process. Flooding of control messages may result in redundant broadcasts and cause serious contention and collision problems in MANETs. This...

- Partial Topology in an MPR-Based Solution for Wireless OSPF on Mobile Ad Hoc Networks
- Using reduced topology within link state routing has proven to be an efficient way to decrease routing overhead while still providing sufficient route quality. There are various ways to achieve topology reduction, based on different ways to form a backbone in the network - this backbone usually originates from the...

- Limited Flooding Protocol for Mobile Ad Hoc Networks
- Mobile ad hoc networks are collections of mobile nodes without any fixed infrastructure or central co-ordinating mechanism for packet routing. Consequently, routing is a challenge. This paper proposes a multipath routing protocol called Limited Flooding. The protocol is fully reactive and does not entail the computation of routing tables. It...

- ARP Broadcast Storm
- Hi All,I'm having a bit of an issue at the moment with arp requests flooding the network from multiple devices, servers, switches etc. Normally you might expect to see aprox 10% arp traffic on the network but I have periods where it is around 85% which tends to bog...

- Mitigating the Flooding Waves Problem in Energy-Efficient Routing for MANETs
- In wireless Mobile Adhoc NETworks MANETs channel and energy capacities are scarce resources, a lot of energy-efficient routing protocols for MANETs have been previously proposed to take into consideration the nodes' residual energies when establishing routes between source-destination pairs. This paper is not trying to introduce a new routing algorithm...

- Defending Against TCP SYN Flooding Attacks Under Different Types of IP Spoofing
- TCP-based flooding attacks are a common form of Distributed Denial-of-Service DDoS attacks which abuse network resources and can bring about serious threats to the Internet. Incorporating IP spoofing makes it even more decoct to defend against such attacks. Among different IP spoofing techniques, which include random spoofing, subnet spoofing and...

- Multiple-Copy Routing in Intermittently Connected Mobile Networks
- Intermittently connected mobile networks are wireless networks where most of the time there does not exist a complete path from the source to the destination. There are many real networks that fall into this paradigm, for example, wildlife tracking sensor networks, military networks, inter-planetary networks, etc. In this context, conventional...

- Search-Quality Tradeoffs for Routing in Non-Ideal Wireless Networks
- Typical wireless routing protocols like AODV/DSR are not scalable to very large networks because they employ flooding for route discovery. Geographic routing protocols like GPSR are highly scalable because they require minimum control overhead, but depend on idealized link quality models such as the unit disk model which are not...

- Location-Based Flooding Techniques for Vehicular Emergency Messaging
- This paper analyzes the scalability of message flooding protocols in networks with various node densities, which can be expected in vehicular scenarios. Vehicle safety applications require reliable delivery of warning messages to nearby and approaching vehicles. Due to potentially large distances and shadowing the delivery protocol must forward messages over...
