Wireless sensor network are usually deployed, possibly in extreme conditions such as mountainous region, and left unattended to function for long time. In order to prolong the network lifetime, it is necessary to minimize the consumption of energy by individual nodes. In addition, it is also necessary to ensure that the average rate of consumption of energy by each node is also the same. The ex...

This paper presents the implementation of a wireless scheduling algorithm that provides backbone Quality of Service (QoS) support to mobile stations. The algorithm described in this paper maps all existing ATM traac types into priorities and weights for a Multiclass Priority Fair Queue (MPFQ) scheduler. The MPFQ scheduler is designed to operate in a wireless base station. A prototype driver has...

Consider the following random process: we are given n queues, into which elements of increasing labels are inserted uniformly at random. To remove an element, we pick two queues at random, and remove the element of lower label (higher priority) among the two. The cost of a removal is the rank of the label removed, among labels still present in any of the queues, that is, the distance from the o...

An Oblivious Priority Queue (OPQ) is a cryptographic primitive that enables client to outsource its data dishonest server, and also securely manage the according priority queue algorithm. Though first OPQ achieves perfect security, it supports only two operations; Inserting an element extracting top-priority element, which are minimal requirement for queue. In addition, this allows adversary ob...

The shift from single-core to multi-core processors in real-time embedded systems leads to communication based effects on timing such as inter-core communication delays and blocking times. Moreover, the complexity of the scheduling problem increases when multi-core processors are used. In priority-based-scheduling, a fixed priority assignment is used in order to enable predictable behavior of t...

IEEE 802.16 standard provides resources to both service classes Constant Bit Rate (CBR) and Variable Bit Rate (VBR). These services require enough resources to transmit data efficiently. In this paper, a Service Based Fair Resource Allocation (SBFRA) Mechanism is proposed, for assessing the required service from Subscriber (SS) along with the channel condition. The proposed model evaluates the ...

Two broader categories of the services are introduced in the paradigm of WiMAX. In IEEE 802.16 standard has added these services and called them as Constant Bit Rate (CBR) and Variable Bit Rate (VBR). Both of these services designed for real time and non real time traffic. As per literature available there is a gap to provide additional resources to fulfill the required service class from the u...

A minimal model based on individual interactions is proposed to study the non-Poisson statistical properties of human behavior: individuals in the system interact with their neighbors, the probability of an individual acting correlates to its activity, and all individuals involved in action will change their activities randomly. The model creates rich non-Poisson spatial-temporal properties in ...

This paper analyzes court priority queuing behavior by examining the time lapse between when a case enters a court’s docket and when it is ultimately disposed of. Using data from the Supreme courts of the United States, Massachusetts, and Canada we show that each court’s docket features a slow decay with a decreasing tail. This demonstrates that, in each of the courts examined, the vast majorit...
