In mobile multimedia communication systems, the limited bandwidth is an issue of serious concern. However for the better utilization of available resources in a network, channel allocation scheme plays a very important role to manage the available resources in each cell, hence this issue should be managed to reduce the call blocking or dropping probabilities. In this paper we have proposed the new...
Mobility management and resource utilization are the two most important research issues in wireless mobile multimedia networks. In order to provide the guarantee of handoff probability; we propose a mobility based call admission control using artificial neural network to predict the accurate future position of mobile user based on the mobility history of the user. For mobility prediction we have used...
Power control and soft handoff are the two essential techniques for effectively increasing the spectrum efficiency in a CDMA based system. Soft handoff (SHO) handles the mobility of mobile terminals while power control aims at minimizing the total interference in a CDMA system. During SHO power control procedure is more complicated since at least two base stations are involved. Soft handoff and power...
Both Microsoft's Windows 7 and Apple's Snow Leopard operating systems claim to provide users with a safer and more reliable environment, but no work has evaluated and compared their resilience against common DDoS attack traffic. The authors compare the effect of this type of attack traffic on both systems installed on the same iMac hardware platform under the same network attack conditions. In particular,...
Apple's iMac computers are promoted by the Apple Inc. to be secure, safe, virus free and fast computers. In this experimental paper, we evaluate the security offered by the iMac computers with its usual Leopard Operating System, against ARP-based flooding attacks in a Gigabit LAN environment. We compared the effect of ARP attacks on Leopard OS against those on the Windows XP-SP2 when installed on...
