Nowadays, multimedia services over wireless networks are increasingly popular. With multicast, many mobile stations can join the same video group and share the same radio resource to efficiently increase frequency utilization. However, users may be located at different positions, and so suffer different degrees of path loss and interference, and receive a different signal-to-interference and no...

Volume I first provides a compact survey on classical stochastic geometry models, with a main focus on spatial shot-noise processes, coverage processes and random tessellations. It then focuses on signal to interference noise ratio (SINR) stochastic geometry, which is the basis for the modeling of wireless network protocols and architectures considered in Volume II. It also contains an appendix...

-Multimedia applications are increasingly seen in wireless service networks. The higher channel rate requirements of certain multimedia services, such as video, places constraints on wireless resources, which must provide high channel rates in the presence of high interference and noise. We propose to increase the channel rate of high rate multimedia users by controlling the effective signal to...

The basis for all network communication is the Address Resolution Protocol, which maps IP addresses to a device’s MAC identifier. ARP resolution has long been vulnerable to spoofing and other attacks, and past proposals to secure the protocol have focused on key ownership rather than the identity of the machine itself. This paper introduces arpsec, a secure ARP protocol that is based on host at...

Previous studies have shown significant differences in the enhancement of star-formation rate (SFR) and efficiency (SFE=SFR/M_mol) between spiral-spiral spiral-elliptical mergers. In order to shed light on physical mechanism these differences, we present NOEMA observations molecular gas distribution kinematics (linear resolutions ~ 2kpc) two representative close major-merger star-forming pairs:...

In this paper, we study slotted Spread Spectrum Aloha with Successive Interference Cancelation at the receiver over a Gaussian channel. We consider a decentralized power control setting in which each user chooses its transmit power independently at random according to a power distribution with continuous support. In this setting, we derive an analytical expression for the expected interference ...

In this article, we study the Leader Election Problem in the Signal-to-Interference-plus-Noise-Ratio (SINR) model where nodes can adjust their transmission power. We show that in this setting it is possible to solve the leader election problem in two communication rounds, with high probability. Previously, it was known that Ω(logn) rounds were sufficient and necessary when using uniform power, ...

and γ = [ IN + ρH H ]−1 11 , where H is a M × N complex Gaussian matrix with independent entries and M ≥ N . These diagonal entries are related to the “signal to interference and noise ratio” (SINR) in multi-antenna communications. They depend not only on the eigenvalues but also on the corresponding eigenfunction weights, which we are able to evaluate on average constrained on the value of the...

In this paper, we study the Minimum Latency Collection Scheduling (MLCS) problem in Wireless Sensor Networks (WSNs) adopting the two interference models: the graph model and the more realistic physical interference model known as Signal-to-Interference-Noise-Ratio (SINR). The main issue of the MLCS problem is to compute the minimum latency schedule, that is, to compute a schedule with the minim...

Abstract—We derive upper bounds on the capacity of an additive Gaussian noise channel with continuous phase modulation (CPM). We propose an MMSE approximation to Laurent’s linear decomposition using an arbitrary number of filtered, linearly modulated pulses. Using this linear modulation structure, we derive capacity bounds for both white and colored noise channels with CPM modulation by showing...
