We extend the previously well-known results on the capacity of wireless networks and present the implications of our results on network scalability. In particular, we find bounds on the maximum achievable per-node end-to-end throughput, e, and the maximum number of simultaneously successful wireless transmissions, N max t , under a more general network scenario than previously considered. Furth...

We give numerically tractable, explicit integral expressions for the distribution of the signal-to-interference-andnoise-ratio (SINR) experienced by a typical user in the downlink channel from the k-th strongest bases stations of a cellular network modelled by Poisson point process on the plane. Our model comprises power-low path-loss model with arbitrarily distributed shadowing, with and witho...

We examine the outage probability of a multi-code DSCDMA system with Minimum Mean Squared Error (MMSE) linear interfenxce suppression. Multi-code DS-CDMA allows different information mtes by varying the number of spreading codes assigned to each user. Power control is used to achieve a set of taryet Signal-to-Inter ference-plus-Noise Ratios (SINRS), and an outage occurs if a user must incnmse t...

This paper describes two novel methods for active detection and prevention of ARP-poisoning-based Man-inthe-Middle (MitM) attacks on switched Ethernet LANs. As a stateless and inherently insecure protocol, ARP has been used as a relatively simple means to launch Denial-of-Service (DoS) and MitM attacks on local networks and multiple solutions have been proposed to detect and prevent these types...

We investigate Arp 295, a pair of interacting spirals at z = 0.023, using optical spectroscopy, Hα imaging, and high-resolution Hα spectroscopy with the Manchester Echelle Spectrograph. We measure scalelengths rexp = 5.24 for Arp 295a and 2.52 kpc for 295b. There is a much smaller Im galaxy, Arp 295c, associated with the larger spiral. Arp 295b is asymmetric with the disk more extended eastward...

In wireless channel the noise has a zero mean. This channel property can be used in the enhancement of the noise performance in the digital receivers by oversampling the received signal and calculating the decision variable based on the time average of more than one sample of the received signal. The averaging process will reduce the effect of the noise in the decision variable that will approa...

A small population of neurons in the hypothalamus is known to promote food intake by releasing inhibitory agouti‑related peptide (ARP) and neuropeptide Y to broad postsynaptic areas. Acute ablation of ARP neurons in adult mice leads to rapid loss of appetite and the development of an anorexic phenotype. Recent studies have suggested that ablation of ARP neurons removes critical inhibition of po...
