Multi-Hop Network with Multiple Decision Centers under Expected-Rate Constraints

Reliability optimization problems with multiple constraints under fuzziness

In reliability optimization problems diverse situation occurs due to which it is not always possible to get relevant precision in system reliability. The imprecision in data can often be represented by triangular fuzzy numbers. In this manuscript, we have considered different fuzzy environment for reliability optimization problem of redundancy. We formulate a redundancy allocation problem for a...

Optimal Bit Allocation Under Multiple Rate Constraints

Outage Performance of Cognitive Multi-Hop Network under Interference Constraints over Nakagami-m Fading

The outage performance of multi-hop cooperative spectrum sharing systems with interference constraints over Nakagami-m fading is investigated. Employing a Decode-andForward (DF) relaying protocol, the closed-form analytic expression is derived for the Outage Probability (OP), which is validated through comparison with results from Monte-Carlo simulations. In addition, the corresponding asymptot...

Multi-hop Virtual Cellular Network

1. Introduction The 3rd generation mobile communication systems, known as IMT-2000 systems, have data transmission capability of up to 2 Mbps [1]. Recently, high-speed downlink packet access (HSDPA) aiming at a maximum peak throughput of around 10 Mbps is under development for the enhancement of the IMT-2000 systems [2]. However, since information transferred over the Internet is becoming incre...

Improving Steiner Trees of a Network under Multiple Constraints

We consider the problem of decreasing the edge weights of a given network so that the modiied network has a Steiner tree in which two performance measures are simultaneously optimized. We formulate these problems, referred to as bicriteria network improvement problems, by specifying a budget on the total modiication cost, a constraint on one of the performance measures and using the other perfo...
