— Wireless user-mobility prediction has been investigated from various angles to improve network performance. Student populations in campuses, pedestrian and vehicular movement in urban areas, etc have been studied by cell phone and mobility management researchers to address issues in Quality of Service (QoS), seamless session handoffs, etc. Access to(More)
User mobility prediction has been studied for various applications under diverse scenarios to improve network performance. Examples include driving habits in cell stations, roaming habits of cell phone users, student movement in campuses, etc. Use of such information enables use to better manage and adapt resources to provide improved Quality of Service(More)
— In this paper, we study the effects of mobility on network parameters in hierarchical ad hoc networks. Several mobility models have been designed and studied to mimic the behavior of real world mobility in networks. They have been successful in modeling the movement of mobile nodes in simulations. However, in this work, we show that several mobility(More)
User mobility influences the performance seen by a mobile device in a wireless network. Knowledge of mobility patterns can be exploited to properly allocate network resources and enhance the performance and quality of service experienced by a mobile device for applications and services. Hence, mobility prediction plays an important role in the efficient(More)
As all can see that the demand of WLAN is increasing gradually, so here it is necessary to improve the performance of WLAN. There are many parameters which can directly affect the performance of WLAN like data rate, modulation scheme, buffer size, RTS threshold etc. One of them is fragmentation threshold. In this paper we are rising up the performance of(More)
Mobile wireless network performance, measured using throughput, call blocking and dropping probabilities and resource utilization, is related to the mobility behavior of users. Statistical information pertaining to user mobility can be exploited to design mobility aware networks. This paper proposes a mobile network design method using prior mobility data.(More)
Inspired by principles and advantages of the group technology (GT) philosophy, part family formation for a virtual Cellular Manufacturing System (VCMS) using Fuzzy logic is designed for dynamic and uncertain conditions. In real manufacturing systems, the input parameters such as part demand and the capacity are fuzzy in nature. In such cases, the(More)
In this paper, we study the effects of opportunistic relay placement on the performance of multihop ad hoc networks. It has been previously shown that multihop mesh networks can aid in enhanced network performance by optimally utilizing power and bandwidth resources. We propose a placement scheme to introduce relay nodes in the network at critical locations(More)
