Joint design of routing and Resource allocation algorithms in cognitive radio based wireless mesh networks. The mesh nodes utilize cognitive overlay mode to share the spectrum with primary users. Prior to each transmission, mesh nodes sense the wireless medium to identify available spectrum resources. Depending on the primary user activities and traffic characteristics, the available spectrum r...

in this paper, downlink resource allocation for a sparse code multiple access (scma) based heterogeneous  cellular networks (hcn) is investigated. the main aim of this paper is to obtain joint power allocation and codebook assignment to achieve the least total system transmit power. in this regard, the proposed objective function is formulated as total transmit power subject to users minimum ra...

Simultaneous routing and resource allocation has been considered in wireless networks for its performance improvement. In this paper we propose a cross-layer optimization framework for worst-case queue length minimization in some type of FDMA based wireless networks, in which the the data routing and the power allocation problem are jointly optimized with Fuzzy distributed H∞ control strategy ....

Resource management in clusters traditionally uses centralized approaches, which restricts the cluster scale. To expand this limit, we develop a multi-agent approach to sharing resources across clusters in a decentralized manner. We organize shared clustered into an overlay network and formulate resource sharing in such a network as a distributed sequential resource allocation problem (DSRAP). ...

This paper addresses the problem of interference aware resource allocation for OFDMA based hybrid hierarchical wireless networks. We develop two resource allocation algorithms considering the impact of wireless interference constraints using a weighted SINR conflict graph to quantify the interference among the various nodes: (1) interference aware routing using maximum concurrent flow optimizat...

The use of relay nodes to improve the performance of BWA networks has been the subject of intense research activities in recent years. Relay enhanced BWA networks are anticipated to support multimedia traffic (i.e., voice, video, and data traffic). In order to guarantee service to network users, efficient resource distribution is imperative. Wireless multihop networks are characterized by two i...

Liveness-enforcing supervisors (LESs) guarantee deadlock-free operations in resource allocation systems (RASs). Given the growing emphasis on higher resource utilization and operational flexibility, it is greatly desirable to obtain the optimal LES that can provide the maximum behavioral latitude. In general, however, computation of the maximally permissive LES is computationally intractable, a...

Three policies, namely Optimal Repacking, Least Load Routing, and Bernoulli Splitting, are considered for dynamic resource allocation in load sharing networks with standard Erlang type statistics. Large deviations principles are established for the three policies in a simple network of three consumer types and two resource locations, and are used to identify the network overrow exponents. The o...

The single vehicle routing problem with multiple routes is a variant of the vehicle routing problem where the vehicle can be dispatched to several routes during its workday to serve a number of customers. In this paper we propose a goal programming model for multi-objective single vehicle routing problem with time windows and multiple routes. To solve the model, we present a heuristic method wh...
