This paper proposes and analyzes bandwidth reclaim scheme for IEEE 802.11 WLAN, which may suffer from severe bandwidth waste resulting from not only the variation of transmission rate and message length but also the overallocation to the real-time traffic in compensating for the delay due to the intervention of non-real-time messages. Built on top of the weighted round robin scheduling policy, ...

intra-abdominal desmoplastic small round cell tumor is a rare entity with a few reports worldwide. this tumor commonly occurs in children and adolescent and occurrence in adult age group is very rare. here, we describe an adult male with symptoms of intestinal obstruction due to abdominal mass, located in splenic flexure. after resection, the diagnosis of intra-abdominal desmoplastic small roun...

We consider differentiated bandwidth allocation for short-range wireless personal communication systems: Bluetooth. Since bandwidth requirements may vary among applications/services, and/or it may change over time, it is important to decide how to allocate limited resources to various service classes to meet their service requirements. We propose a simple and eff icient bandwidth allocation mec...

We introduce two new classes of graphs which we call convex-round, respectively concave-round graphs. Convex-round (concave-round) graphs are those graphs whose vertices can be circularly enumerated so that the (closed) neighborhood of each vertex forms an interval in the enumeration. Hence the two classes transform into each other by taking complements. We show that both classes of graphs have...

The performance of different ATM switch buffer queuing schemes for round-robin and weighted round-robin didn‘t have too much difference. This paper presents the discrete-event simulation provides detailed, accurate network simulation results and it observed a wide variety of network statistics. The software simulation package, OPNET, which specializes in discrete-event simulation of communicati...
