Real-time data transmission is one of the objectives MANET (mobile ad-hoc network) to handle emergencies like a forest fire, flood, and earthquake. In this scenario, quick delivery itself challenging task for there possibility load imbalance due packet in between source-destination pairs via shortest path congestion or control overhead. paper, novel routing protocol, called ACOLBR (ACO based ba...

In the previous lectures we talked about the inefficiency of equilibrium states. We defined the concepts of the Price of Anarchy (PoA) and the Price of Stability (PoS). We mentioned two problems: 1. Infinitesimal Flows-For which we showed that an equilibrium state can be suboptimal. We talked of Brass Paradox, as a situation where adding another channel or route actually decreases the performan...

The selection of an appropriate and stable route that enables suitable load balancing of Internet gateways is an important issue in hybrid mobile ad hoc networks. The variables employed to perform routing must ensure that no harm is caused that might degrade other network performance metrics such as delay and packet loss. Moreover, the effect of such routing must remain affordable, such as low ...

A Wireless Sensor Network (WSN) is a network comprising of wirelessly linked sensor nodes. These low computational, tiny devices can communicate in short distances. Each sensor node consists of sensing, data processing, and communication components. To ensure scalability and to increase the efficiency of the network operation, sensor nodes are often grouped into clusters. A lot of work is being...

Spatial and temporal information about traÆc dynamics is central to the design of e ective traÆc engineering practices for IP backbones. In this paper we study backbone traÆc dynamics using data collected at a major POP on a tier-1 IP backbone. We develop a methodology that combines packet-level traces from access links in the POP and BGP routing information to build components of POP-to-POP tr...

The deployment of such networks has allowed clients to gain access to publicly available broadband networks....

In this paper, we consider the statistical decision processes behind a linear and a differential cryptanalysis. By applying techniques and concepts of statistical hypothesis testing, we describe precisely the shape of optimal linear and differential distinguishers and we improve known results of Vaudenay concerning their asymptotic behaviour. Furthermore, we formalize the concept of “sequential...

number tags, discriminative responding would be maintained in shift. After the initial shift, Group BA was shifted to the series RRN and NRRN, in which pellets were used as the reinforcer. Finally, confinement time on R trials was decreased from 15 s to 7 s.
