With the increasing demand of wireless body area network (WBAN) for patient monitoring systems, it is necessary to develop efficient energy management systems to either prolong node battery replacement time or to develop batteryless WBAN nodes. In this paper, we introduce an energy harvesting WBAN architecture that combines the energy harvesting system and an adaptable duty cycle adjustment alg...

T paper is the experimental follow-up to Langville and Stewart (2002), where the theoretical background for the nearest Kronecker product (NKP) preconditioner was developed. Here we test the NKP preconditioner on both Markov chains (MCs) and stochastic automata networks (SANs). We conclude that the NKP preconditioner is not appropriate for general MCs, but is very effective for a MC stored as a...

This paper proposes a microstrip patch antenna for 2.45 GHz Industrial Scientific Medical (ISM) band Wireless Body Area Network (WBAN) applications. To enhance the front-to-back ratio (F/B) and specific absorption rate (SAR), an electrically coupled LC resonator is introduced. The overall dimensions of the proposed antenna are 54 mm × 45 mm × 2.4 mm and it has a gain of over 1 dBi for the entir...

A desirable location privacy protection scheme is important for securing node communication in a wireless local area network (WLAN). By pausing transmission or updating nodes independently, such a scheme can prevent nodes from being tracked or communication information from being snapped. This paper first introduces an ID Tracking Approach to show that nodes which swap IDs with other nodes in e...

In this paper, we discuss the details of a Code Division Multiple Access (CDMA)-based multiplecasting system in a wired Local Area Network (LAN). This technique enables multiple users to transmit and receive data simultaneously among themselves using a single serial wire link at any given time, hence, called multiplecasting. This is unlike the method followed with the Ethernet in a wired LAN. W...

This paper addresses the types of QoS dissatisfaction caused by imbalance of the initial I/O workload pattern and storage performance across multiple storage servers in a storage cluster. It next proposes a systematic scheme to resolve the QoS problem that periodically monitors the QoS satisfaction level, analyzes the causes of the QoS problem, and performs data migration based on the analysis ...

Paging activity can be a major factor in determining whether a software workload will run on a given computer system. A program’s paging behavior is difficult to predict because it depends not only on the workload processed by the program, but also on the level of storage contention of the processor. A program’s fault rate function relates storage allocation to the page fault rate experienced w...

Transit fare arbitrage is the scenario when two or more commuters agree to swap tickets during travel in such a way that total cost is lower than otherwise. Such arbitrage allows pricing inefficiencies to be explored and exploited, leading to improved pricing models. In this paper we discuss the basics of fare arbitrage through an intuitive pricing framework involving population density. We the...

Computational grids such as the Information Power Grid [1], Particle Physics Data Grid [2], and Earth System Grid [3] depend on TCP to provide reliable communication between nodes across a wide-area network (WAN). Of the available TCP implementations, TCP Reno and its variants are the most widely deployed; however, Reno’s performance in computational grids is mediocre at best. Due to conflictin...
