Device-to-Device (D2D) is considered as a promising technique to improve resource utilization and provide new application in future wireless networks. This paper addresses the problem of radio resource allocation for D2D communication. Basically, resource allocation can be carried out in centralized or distributed manner. In this paper we discuss the mechanisms of distributed resource allocation and...
In this paper, power allocation problem is presented for device-to-device (D2D) communications underlying cellular networks in multi-user scenario. In this scenario, multiple D2D pairs are allowed to share one cellular resource. As a preliminary study, we consider the scenario with only two D2D pairs and propose a power optimization scheme under this scenario. For cellular link and the D2D links sharing...
Device-to-Device (D2D) communication underlying cellular networks and reusing cellular resources enhances the network capacity and spectrum efficiency, but causes severe interference which can degrade the system performance. In this paper, we concentrate on managing the downlink interference from D2D communication to cellular networks when sharing channel resources. First of all, a strategy based...
There are many devices embedded in a smart home environment. It is a challenge to operate these devices due to the heterogeneity and the mobility of them. In this paper, we propose a context-aware resource management framework, which aims to (1) discover available resources and update the states of those devices according to the changes of contexts; (2) allocate suitable resources to meet the needs...
A new kind of multi-resources leveling model with changeable resource intensity is presented in this paper. Prolonging of activity duration is allowed in order to decrease resource intensity of activity in this model. A dimensionless variable named as duration prolonging rate is introduced to show the prolonged degree of activity duration. Time constraints among activities can be automatically satisfied...
