Method of reliability and availability analysis from the dynamic properties of routing and forwarding paths

  • Careglio D.
  • Demeester P.
  • Papadimitriou D.
  • Tarissan F.

Confronted to the increasing dynamic of Internet routing system and its underlying topology, we propose a reliability and availability analysis method based on the characterization of the dynamic properties (in particular, the stability properties) of routing paths and their corresponding forwarding paths. The key driver underlying this method is that ...

Layer Transmission for Cooperative Communication with Asymmetric Relay Channels

  • Han F.
  • Jiang Q.
  • Meng Y.
  • Shen G.

In downlink relay system, the conventional straightforward relaying scheme named decode-and-forward (DF) protocol is used at relay station (RS) to decode the data received from the base station (BS) and forward the decoded data to the mobile station (MS) to improve the spatial diversity gain. It is not spectrum efficient ...

An Evolution of Load Balancing Strategies in Co-Channel HetNets: Dynamic eICIC to Multi-Streaming

  • Pupala R.
  • Vasudevan S.
  • Venkatesan S.

Range extension of pico cells facilitated by muting of macro cells has been the main load balancing strategy for LTE co-channel HetNets and standardized under the moniker of enhanced Inter-cell Interference Co-ordination (eICIC) in 3GPP. In order to adapt to varying load due to user mobility or traffic activity, both ...

Witnessing Program Transformations

  • Namjoshi K.
  • Zuck L.

We study two closely related problems: (a) showing that a program transformation is correct and (b) propagating a program invariant through a sequence of transformations. The second problem is motivated by an application where invariants on a program are used to enhance both the scope and the quality of the ...

SDN programmability theoretical and standardization aspects

  • Papadimitriou D.
  • Sales B.

SDN research directions as outlined in IRTF RG [1] outlines i) The need for more flexibility and programmability at the data plane level and ii) The need for higher-level languages for programming together with testing and debugging. There are three fundamental challenges behind these directions (assuming that local function or ...

Enabling Data Offload and Proximity Services Using Device to Device Communication over Licensed Cellular Spectrum with Infrastructure Contol

  • K S.
  • Sivanesan K.
  • Vasudevan S.
  • Zou J.

The viability of device to device(D2D) communication on uplink resources as also the benefits accruing from network control over such communication, on licensed spectrum, are quite well understood today. We investigate the merits of a particular system instantiation based on these two tenets. The challenge of scheduling communication between two ...

Performance analysis for device-to-device communications with optimal power control

  • Cai L.
  • Liu Y.
  • Yang K.

Power control is an effective method to guarantee the resource sharing between cellular and D2D links for D2D (device-to-device) communications. In this work, we study the power optimization to maximize the sum rate of all coexistent links. We explicitly put priority for cellular link to guarantee QoS (quality of service) ...
